ABSTRACT

The development of international health from a historical point of view has undergone major advances in recent times and constitutes a substantial part of the current agenda for historians of medicine. Within this framework, and focussing on a specific case study (international responses to poliomyelitis outbreaks in the 20th century), we explore the main actions and achievements of agencies such as the WHO and other private and international scientific organizations. Furthermore, this paper seeks to identify the Spanish presence and absence in these activities, their causes and consequences.

1. Introduction

"For seventy years, polio traumatized the world" 1. Mark Shell begins his well-known monograph on the disease with these words, with which he sought to give an idea of the feelings of fear of its terrible consequences and the lack of effective remedies to hold it back in the first half of the 20th century and even later. If the problem of polio was a world-wide problem, especially concentrated in western countries, the hopes raised by the appearance of the first effective vaccines were also world-wide. The globalization of preventive activities, including the active immunization of populations against infectious diseases such as poliomyelitis, remains a challenge and an objective to be achieved. The inception of responses to this disease at the international level has yet to be studied in its entirety.

The emergence of poliomyelitis outbreaks in the middle of the twentieth century, with special intensity in developed Western countries, led to a series of scientific meetings of virologists, epidemiologists, paediatricians and public health workers. The most significant activities related to infantile paralysis were the following: a) the birth of the World Polio Congresses in 1948, b) the reports of experts promoted by the World Health Organization, c) the conferences promoted by the European Association against Poliomyelitis, and d) the systematic introduction of monographic sessions in national and international paediatric congresses. One of the main aims of all these activities was to seek international consensus on: technical procedures in laboratory settings for the preparation of poliovirus cultures, the use of different types of vaccines in public health programmes, the design of publicity campaigns, the organization of rehabilitation services for polio patients, and the use of natural physical agents as therapeutic measures, among other issues.

The first years of the 21st century have seen an increase in the historiography devoted to International Health 2, which includes an in-depth analysis of the birth of some of the main international agencies and the role they played in the transformation observed in the approach to International Health problems from the earliest International Health Conferences in the 19th century up to the creation of the WHO. It has been shown how the figure of the "expert" emerged and acquired importance in the field of International Health. There have also been studies on some of these international agencies in specific countries and their approach to certain health problems 3 and on their relationships with and influence on the countries' health authorities 4. However, no analysis has yet been made of the role that these international agencies may have played in the design and implementation of strategies against the epidemic presence of poliomyelitis in Europe after the Second World War. No studies have addressed the Spanish participation (if any) in this fight against the disease, and this is the aim of the present paper 5. Our initial approach here centres on two aspects. First, an analysis of the main contents of technical reports and international conferences on poliomyelitis between 1948 and 1960s and, in general terms, the most important strategies and policies in the international setting. Second, we attempt to determine the role played in these international events by researchers and other figures involved in Spanish health policies 6.

This paper is part of a wider study that aims to offer a historical model of how scientific international developments and public health advice -universal in design- were received and implemented (or not implemented) in local settings and how local traditions and circumstances influenced final outcomes 7. In fact, polio may be seen as an excellent field trial for the application of certain concepts from social sciences, including "policy transfer", a process by which knowledge about policies, administrative arrangements, institutions and ideas in one political setting is used in the development of policies, administrative arrangements, institutions and ideas in another field 8. The case study will focus on Spain during the period of Franco's dictatorship.

The main historical sources used are the following: 1) Four Technical Reports on Poliomyelitis (1954-1960) by the WHO Committee of Experts; 2) Proceedings of the European Symposia promoted by the European Association against Poliomyelitis (1948-1966); 3) Proceedings of the World Polio Congresses (1948-1960) and 4) Spanish sources: both official and professional documents.

First of all, we need to understand the foreign affairs situation and the global political issues within the international system involving Spain between 1940 and 1970 as well as the role played by polio in these questions. We then need to analyze the framework of health policies related to polio as carried out by international agencies (e.g., the WHO and European Association Against Polio) or by the institutions behind the organization of international congresses on polio.

 

2. The difficult international relations of Franco's regime and polio outbreaks

Apart from some isolated outbreaks before the Spanish Civil War, such as the Madrid epidemic in 1929, polio was contemporary with the Francoist regime. Regarding foreign policy, Spain moved from international isolation and exclusion from the UN and all its organizations, to gradual incorporation from 1950 onwards into agencies such as FAO, UNESCO, WHO, UNICEF and ILO and, finally, to permanent membership of the UN in 1955. However, this "rehabilitation" of the Francoist regime was limited and caused misgivings in Western countries as well as involving tremendous political and economic costs. The polio epidemics paradoxically represented a kind of legitimization of the regime, given its character as a "disease of civilization" 9, a disease of developed countries where sanitary measures avoided contact of the young with the virus and therefore prevented them from developing immunity. To emphasize the close relationship between development and poliomyelitis that we have just mentioned, Payne launched a new hypothesis that endowed epidemiological data and serological surveys with the value of indicators: as the rates of infant mortality in a given geographical area show a tendency to fall, the incidence and prevalence of polio will increase (the Payne effect). This idea was used as a political argument in some countries and also, particularly, in Spain. Numerous witnesses agreed -in the words of one of the authorities of the time: "as in almost all countries with a high standard of health, in Spain poliomyelitis tends to increase at the same time as infant mortality tends to fall" 10.

Therefore, in spite of the internal disputes within the different factions of the regime on how to cope with the epidemics and how to transmit health information to the population, efforts were made from the very beginning to attend international forums at which the issues surrounding polio were discussed. The participation of a country with an antidemocratic regime and low international standing in these scientific meetings meant a great deal to the political authorities.

 

3. The WHO poliomyelitis programme

Evidence of interest in poliomyelitis appears in the earliest documents of the international organization. At the First World Health Assembly of 24 July 1948, within the section on "Virus Diseases", a proposal was presented by the French Delegation on Acute Anterior Poliomyelitis, due to the increase in severe forms of polio in numerous countries that "had reached disquieting proportions" 11. One of the most important issues discussed was that polio should be studied on an international basis, in close collaboration between epidemiologists and laboratory and clinical experts: "The disease lent itself to study by visiting teams. The present approaches were highly expensive for small countries -in particular the use of monkeys for experimental purposes- and the problem could best be studied by international action".

The final resolution of the Health Assembly was the following:

"The appropriate division of the Secretariat shall be immediately instructed to conduct an investigation into poliomyelitis, and recommends:

(1) that such studies shall be based upon the first results achieved by the Brussels and New York Conferences and shall pave the way for the future work of similar conferences, which should receive the support and encouragement of the WHO.

(2) that a report, in the form of a restatement of this important question, shall be submitted to the second Health Assembly" 12.

The words quoted above clearly show the WHO's interest in poliomyelitis from the very start of its operations in 1948; but it also shows how the research into the disease by the WHO was closely linked to the activities undertaken that year against polio on a world-wide and Europe-wide basis. As we shall see later, the Brussels and New York Conferences respectively constituted the embryos of the future European Association against Poliomyelitis and the First International Poliomyelitis Conference. Both initiatives were set in motion with the intention of fighting against poliomyelitis, which emerged as an important public health issue in the Western world after the Second World War. The extent to which the WHO committed itself to cooperate with and support both initiatives in its First World Health Assembly is also clear.

From 1953 onwards, the WHO also included polio among its own priorities, probably because of the weight in the Organization of severely affected countries that were investing substantial human and economic resources in research, as was the case of the USA and some European countries. The Third World Health Assembly stressed the desirability of international guidance on measures to be taken to prevent the spread of poliomyelitis. It recommended the establishment of a committee of experts to co-ordinate research, with a view to obtaining the information necessary to specify effective preventive measures. The first session of the Committee was held in Rome from 14 to 19 September 1953, immediately after the Sixth International Congress of Microbiology.

The specific means by which the WHO became involved in the question of polio was thus the common way to deal with this type of problem. For advice on more technical questions, the Secretariat headquarters appointed a panel of experts, from which were selected Committees of Experts to recommend policies 13. Between 1953 and 1960 the executive board, whose functions included the setting up of these Committees of Experts 14, appointed several specific committees to deal with the subject of polio. The importance given to the question was further demonstrated when the meetings of the committees were published in the form of reports, sanctioned and approved by the General Assembly; this only happened in cases which were considered to be highly important and required international diffusion. These reports were published either partially or in their entirety. In the case of polio, all reports were published in their entirety.

The Committees of Experts were (and still are) the key to the workings of the Organization. Their purpose was to give technical advice on particular questions. The reports, of which four were published between 1953 and 1960, did not necessarily express the view of the Organization, but they were an essential tool in forming policies and preparing programmes.

Individual members were appointed on their own merit, not as representatives of governments, institutions or associations, although efforts were made to ensure some geographical spread. The criterion of competence rather than nationality led to a kind of trans-national community of experts 15 with roots in the international public health movements of organizations founded prior to the setting up of the WHO, such as the Office International d'Hygiéne Publique (OIHP).

Who were the members of the Expert Committee on Polio? Two members of the Secretariat were key figures in the early history of the WHO: W. Bonne, director of the Division of Communicable Diseases and A. Payne, professor and chairman of the Department of Epidemiology and Public Health, Yale University School of Medicine, formerly Chief Medical Officer for virus diseases. The other experts on the committees varied over time. The total number of committee members fluctuated between 10 and 15. Of the permanent members, four appeared in each and every one of the Reports. Three were from the field of experimental laboratory research: Sven Gard from Sweden, John Gear from South Africa, and the Head of the Virus Service of the Institut Pasteur, Pierre Lépine, probably the most important virologist of his time. The fourth, the professor of preventive medicine at the Yale University School of Medicine, John Paul, was a key figure in the history of polio and author of the first history of the disease 16; he acted as chairman. The remaining members depended on the content of each report and on the importance of a particular issue at any given time. For instance, the epidemiologist Thomas Francis 17 appeared in the First Report of 1954, at a time when preparations were in hand for the clinical trials of the Salk vaccine, carried out under his direction in April 1955. Likewise, Albert Sabin, professor of paediatric research at the University of Cincinnati and creator of the oral polio vaccine (OPV), was invited to take part in the Reports of 1956 and 1958 when the scientific forums were discussing anti-polio vaccines and research on inactivated vaccines and attenuated live virus vaccines.

3.1. The contents of the Reports

Between the first report of the Expert Committee (1954), which dealt with the general aspects of the disease (causal agents, acute clinical symptoms, laboratory methods and general and non-specific preventive measures) 18 and the second report in 1958 19, a series of important advances in research made it necessary to publish a monograph on the new vaccination procedures. Above all, there was exceptional interest in the mass media about the widespread clinical trials carried out by the epidemiologist Thomas Francis with Jonas Salk's injected polio vaccine (IPV) 20. Its success in the USA encouraged other research teams from different countries to prepare vaccines with inactivated viruses.

However, the committee believed that the general prophylactic measures (except active immunization with convalescents' serum) listed in the first report retained all their value. These measures included the following: notification of polio cases, isolation and care of the patients, protection of families and collectives exposed to the infection, and appraisal of the risk of paralysis as a consequence of both vaccinations and surgical procedures. The production of vaccines continued to pose problems and difficulties that required rigorous and constant surveillance of the preparation procedures.

The decision to undertake or intensify a vaccination campaign was the competence of the national authorities, who best understood the importance of poliomyelitis in comparison with other urgent public health problems in each country. Polio vaccination might be more suitable in some countries than in others. It was necessary to carry out, in each country, an in-depth study of the background of the problem and to attempt to foresee its evolution over the next ten years. The first signs of the imminence of an outbreak were as follows: a) decrease in infant mortality to below 75 deaths per 1,000 children and 2) the appearance of polio cases not only among breast-fed babies but also in older children. When at least 20% of victims were over ten years of age, an intensification of the disease could be expected.

On the other hand, it was considered of great importance to keep full records that provided information on doses and dates of inoculation plus a statement on possible adverse reactions.

The fourth and final meeting of the Expert Committee during this period took place in Washington in June 1960 21. It was held in a mood of optimism as a result of the potential of oral polio vaccine (OPV) for the mass immunization of the population and the effectiveness of the vaccine, which caused a sharp fall in morbidity rates in countries in which it was used. In the majority of countries, it was decided to immunize with the oral vaccine, since it was cheaper, easier to administer and allowed collective immunity to be given to the population.

Spain played no part at all in any of the four reports. There was not a single Spanish representative on the committees and subcommittees, not even as "temporary adviser", and there is no information on epidemiological data or any activities being carried out. This information was available for a large number of countries, some geographically smaller and with smaller populations than Spain. However, this is consistent with the Franco regime's reluctance to admit the presence of disease and the circumstances of isolation during the early years of the dictatorship. It should be borne in mind that Spain was excluded from the WHO until 1951. Although this exclusion may be explained by the regime's political ideology, we agree with Barona and Bernabeu in also relating it to the setbacks suffered by Spanish public health after the Civil War, due to the exile and repression of health professionals 22. In fact, two of the exiled republicans -Marcelino Pascua (1897-1977) and Santiago Ruesta Marco (1899-1960)- formed part of the WHO as experts and played a significant role in the organization. Marcelino Pascua arrived in the organisation in 1948 as a health statistician and retired in 1966 after almost ten years as consultant to the Director General of WHO 23. Nevertheless, as we shall show, it would not be until 1958 that Florencio Pérez Gallardo (1917-2006), director of the Laboratory of Virology, National Health School (Madrid), represented the WHO as delegate of the European Regional Office in the V Symposium of the European Association against Poliomyelitis.

What repercussions did the warnings and recommendations of the WHO have in Spain? We are probably still not in a position to make a detailed report, but we see a health administration with significant internal disputes that undoubtedly delayed, for instance, the implementation of vaccination campaigns and did not help basic research 24. The economic hardship of the early years of the Franco regime also contributed to this situation and to the delayed implementation of specialized care for poliomyelitis patients 25. However, eminent figures and groups were active in the country, and Spain did take part in another type of event, as we shall discuss below.

 

4. International Poliomyelitis Conferences

4.1. From epidemiology to vaccination against poliomyelitis

The National Foundation for Infantile Paralysis celebrated its tenth anniversary by funding the First International Poliomyelitis Conference in New York in 1948. The objective was to coordinate and assess the progress made by medicine in the study of infantile paralysis during the previous decade. The other four conferences took place in Copenhagen (1951), Rome (1954), Geneva (1957) and again in Copenhagen (1960). They were all funded by the above-mentioned North American organization, under whose auspices the International Poliomyelitis Congress was set up. It was entrusted with the practical arrangements of the Conferences and was headed by Basil O'Connor, president of the National Foundation. The minutes were published by J.B. Lippincott 26. The work carried out by the North American organization -the National Foundation for Infantile Paralysis- may be considered partly comparable to that done by the Rockefeller Foundation (RF), but solely in reference to poliomyelitis and rather more limited in time. We could therefore say, as some authors have done in interpreting the role of the major international agencies -notably the RF and the League of Nations Health Organization (LNHO)-, that this organization carried out a simple colonial strategy linked to the interest of American industry 27. However, as in the case of the RF and the LNHO, we can add another interpretation which also includes the significant benefits 28 brought by the experience of polio that this organisation acquired and the resources that it could bring for a more effective fight against the epidemics of poliomyelitis and their after-effects in Europe. Indeed, apart from the first conference, all of the rest were held in European cities that were important both as victims of epidemic polio outbreaks and for their traditional position in the field of International Health.

There was a gradual change in the subjects covered in the different conferences. The first (1948) began its sessions with a talk by Albert Sabin 29 underlining the importance of polio as a world-wide problem. He described the epidemiological patterns of the disease in different parts of the world, and provided data on the outbreaks in both rural and urban communities in the United States, Sweden and Denmark as well as in different racial groups. He emphasized the increase in age of polio victims as one of the main results of his research. The pathogenesis, treatment of polio and rehabilitation issues were also addressed. In a session on immunology and chemotherapy, J. Paul presented the results of his research on the different strains of the polio virus, which proved to be fundamental in the subsequent development of an anti-polio vaccination 30. In the final session, delegates from twenty-eight countries (which did not include Spain 31) gave reports on the epidemiological characteristics of polio and the treatments applied in their setting 32.

In the second Conference (1951), the session that aroused the liveliest debate with the greatest number of contributors was devoted to the differential diagnosis of acute poliomyelitis 33. In this session, Robert Debré (1882-1978), one of the founders of modern paediatrics and President of the French Institut National d'Hygiêne, and Stéphane Thieffry concentrated on paralytic polio, while Jordi Casals presented a specific complement fixation test for the disease, and Jonas Salk gave an immunological classification of the polio virus. There were numerous sessions on the treatment and ecology of the disease, as well as on virology, with contributions on the interactions of the virus with host cells, immunity in polio, the viruses of the Coxsackie group and an interesting intervention by J. Enders on the growth of the polio virus in human embryo tissue 34.

At the third Conference (1954), studies on physical medicine, rehabilitation, orthopaedic treatment and the acute phase of polio shared the floor with those focused on the social aspects of the disease 35. The latter, centred on Italy, the Scandinavian countries and the United States, presented the need for the work rehabilitation of polio victims suffering from the after-effects of the disease. However, the greatest expectation was aroused by the report of J. Salk on the results of his vaccine and A. Sabin's contribution on new inactivated strains of the virus for immunization in a session opened by Pierre Lépine, head of the Virus Service of the Institut Pasteur, who presented the current epidemiological situation of polio 36. J. Enders also attended this congress with his latest work on the development of the poliovirus in tissue cultures 37, presented in closed session with the projection of a film on the production of the polio virus 38.

At the fourth Conference (1957), there were numerous papers on the study of the polio virus and on the different vaccines available, both those prepared from deactivated virus (such as those of J. Salk and D. Bodian), and those using attenuated virus, most notably those of A. Sabin, H. Koprowski and A. Payne. Extensive time was also devoted to the respiratory problems of polio sufferers and their care in special centres or at home, as well as the treatment of severe forms of polio. These interventions made clear a new challenge, stated by James Wilson in the introduction to this session: it was not enough to save the patient's life; the life saved must be as useful as possible 39.

The fifth Conference (1960) did not include any reports from the official delegates on the polio situation of their respective countries and was given over entirely to the study of the polio virus and the vaccines manufactured as a result. Papers on the former dealt with its morphology, chemical structure and mutations and with the immunological reactions it causes. Results were reported on the application of vaccines with deactivated viruses created in the United States, Canada, Denmark and Norway; the highlight was Salk's speech on the duration of the immunity provided by his vaccine 40. The results achieved with vaccines produced from attenuated virus were also presented, including those of Sabin in Colombia, Costa Rica, Nicaragua and the Soviet Union 41. The production of antibodies with this type of vaccine led to the participation, among others, of H. Koprowski, H. Cox and Sabin himself 42, while the effect of attenuated virus vaccines on the population received the attention, among others, of J. Paul 43, whose participation was very active throughout these congresses.

4.2. The Spanish presence and its repercussions in the daily and specialized press

There was Spanish representation in all but the first Conference (1948). This Spanish absence went unremarked in the daily press and in the medical journals we have consulted. There was an official delegation at the second Conference (1951), comprising Florencio Pérez Gallardo (1917-2006), director of the Virology Laboratory of the National School of Health and Darío Fernández Iruegas, professor of paediatrics in the Faculty of Medicine of Madrid and director of the Hospital-Asylum of San Rafael (Madrid). Dario Fernández presented a report on the situation of polio in Spain 44. He reported on the 1929 epidemic in Madrid, from where the epidemic extended throughout the country. The number of cases did not exceed six per 100,000 inhabitants in any province, and its geographical distribution remained practically identical every year from 1930 to 1950. The behaviour of the disease in Spain contrasted with that observed in the rest of Europe. The Spanish epidemic outbreak in 1929 had no equivalent in other countries of the continent, where the disease increased between 1935 and 1940 while it became less frequent in Spain. In 1942, the decrease in the United States and Europe coincided with a rise and subsequent fall in Spain, where epidemic outbreaks were detected eight years later in Madrid, Valencia, Santander and Pontevedra. The main conclusion of the report was that in Spain, as in the rest of the world, polio was tending to increase. On this occasion, the daily press did cover the attendance of the Spanish delegates at the Copenhagen conference and emphasized the announcement there of the possible imminent discovery of effective remedies to combat the disease 45.

The third Conference (1954) was attended by several Spanish physicians. Apparently there was no official delegation, although Juan Bosch Marín, head of the Child Health Service of the Dirección General de Sanidad (General Health Department), was present. Francisco Barnosell Nicolau, orthopaedic surgeon, director of the Institute of Corrective Medicine of Barcelona and head of the Central Rehabilitation Service of the Hospital Clínico (Barcelona), gave a showing of the film "Physiotherapy and re-education in polio sequela" Bosch Marín intervened in the discussion on respiratory disorders in polio due to bulbar involvement in polio and outlined his favourable experience with the use of respiratory tanks, the only devices available in Spain, as he stressed, for the treatment of respiratory complications 46.

In the discussion following the section on physical medicine and rehabilitation in polio, mention was made of "A critical examination of the Kenny method in the treatment of polio" by Vicente Sanchis Olmos (1911-1963), Head of the Orthopaedic and Traumatology Service of the Hospital de la Cruz Roja (Madrid) and member of the National Institute of Re-education of Invalids in Madrid. His paper studied two of the factors that might aggravate the acute phase of polio and were under debate: irradiation of the medulla with short-wave and with X-rays 47.

The congress was also attended by: the neurologist Ramón Sales Vázquez (1971), Chief of the polio service of the Clinical Hospital of Barcelona; Francisco Barberá Carré, specialist in functional re-education; the paediatrician Darío Fernández Iruegas; and Víctor Meana Negrete, director of the National Maritime Sanatorium of Pedrosa (Santander) and director of the Hospital-Asylum of San Rafael (Madrid) on the death of Fernández Iruegas 48.

The daily press reflected the results of the first vaccinations against polio carried out in the United States and announced at this third conference 49. La Vanguardia gave it full coverage from its inauguration and, considering the different contributions, concluded that there were grounds for cautious optimism in the battle against polio, identified as "the disease of civilization" 50, because "it increased at the same time as living standards" 51. It highlighted the Spanish participation and stressed the importance of the success obtained with the vaccine developed by Salk.

There was an official Spanish delegation at the fourth Conference (1957), led by Bosch Marín, vice-president of the European Association against Poliomyelitis. The scientific delegation was made up of various paediatricians: Ciriaco Laguna Serrano (1905-1990), professor of paediatrics from Madrid; Antonio Galdó Villegas, professor of paediatrics from Granada; Manuel Cruz Hernández, professor of paediatrics from Cádiz; Manuel de la Iglesia and Espadaler from the department of paediatrics in Barcelona; and Darío Fernández Iruegas, as well as orthopaedic surgeons Francisco Barnosell and Esteve de Miguel, functional re-education specialist Francisco Barberá Carré; neurologist Ramón Sales Vázquez, Director of the Department of Infantile Paralysis of the Hospital Clínico of Barcelona, who also represented the Medical Faculty of Barcelona; and José María Sala Ginabreda, from the Municipal Hospital of Infectious Diseases in Barcelona 52.

Bosch Marín, in his report on the situation in Spain, emphasized that the Payne phenomenon was taking place, with an increased incidence of polio in parallel with the improved state of health. There had been more than1500 cases annually since 1950, and 91% of cases were in children under five years old; the morbidity was virtually identical between small towns and cities. He also mentioned the existence of 150 artificial respirators, stressed the growing interest in disability as an after-effect of the disease, and reported the recent creation of the National Rehabilitation Board 53. For his part, the orthopaedic surgeon Esteve de Miguel took part in the scientific exhibition of the Conference with a study on precautions against the shortening of the lower limbs in paralysed patients 54.

This conference in Geneva received the greatest coverage in the Spanish press yet. It was particularly important because of the reports on the fifty million vaccinations in the United States and on the immunization campaigns conducted in Scandinavian countries 55. Bosch Marín attracted the attention of the press by announcing that the next assembly of the European Association was to be held in Madrid in 1958 56, and they reported his statements on his return from the congress to the effect that "Polio has never been a health problem in Spain", although at the time there was a noted tendency for it to increase, as it had in the first three decades of the century in all developed countries; he therefore recommended vaccination in the future, in line with the other participants in the conference 57.

The fifth Conference (1960) was attended by doctors from the National Hospital for Infectious Diseases (Madrid): Juan Figueroa Egea, clinical head, and Juan Torres Gost, director of the hospital; specialists in re-education and rehabilitation, Arguelles from Madrid, F. Barberá Carré and Luis Portal Llamedo from Barcelona; the neurologist Sales Vázquez, and Vicente Sanchis-Bayarri, assistant professor of Public Hygiene and Microbiology from Valencia 58. The latter, in his account of the conference, indicated that all of the participants had been invited to take part by the Organizing Committee 59. The publication reporting the minutes of the congress included no contribution from the Spanish participants 60.

Among those attending the conferences, the evidence shows that among the Spanish representatives there was a majority of paediatricians, orthopaedic surgeons, rehabilitation experts and neurologists. Francisco Pérez Gallardo, director of the Virology Laboratory of the National School of Health (Madrid) and Sanchis-Bayarri, author of pioneering studies in Spain on the polio virus were only present at the second and fifth Conferences, respectively 61. The presence of Sanchis-Bayarri indicated a change in the trend of the subjects covered at the conferences: studies on clinical practice, diagnosis and surgical and orthopaedic treatment lost ground to contributions on the virus and on the different vaccines available to prevent the disease. For his part, the presence of Pérez Gallardo in 1951, just when Spain was admitted to the WHO, could be interpreted as a clear manoeuvre to give political validity to Franco's regime, represented by a competent professional linked to lines of international epidemiological research in this field.

 

5. Symposia of the European Association against Poliomyelitis

Following an initiative of the Belgian Professor L. Laruelle, an assembly of epidemiologists, clinicians and researchers was brought together in Brussels in 1948, constituting the core of a new group that became the European Association against Poliomyelitis, set up in 1951 in Brussels. Its first Symposium was held in April 1953 in the Serum Institute of Copenhagen 62 and was dedicated to the epidemic in this city from July to December of the previous year. This epidemic was the worst that Denmark had had ever suffered; its importance was due not only to the number of people affected (including paralytic forms) but also to the severity of the respiratory problems. These required the generalized use of tracheotomy, combined with some methods of controlled respiration derived from anaesthesia 63. Between 1953 and 1966, eleven Symposia were held in different European cities, every one or two years. The first and second Symposium reports were published with the support of the Archives belges de médecine sociale, hygiéne, médecine du travail et médecine légale 64. The first President was P. Lépine (Paris), head of the Virus Service of the Institut Pasteur. The other members of the permanent committee of the European Association against Poliomyelitis were professors and doctors from Copenhagen (Prof. Lassen), Berne (Dr. Vollenweider), London (Dr. Bradley, Ministry of Health), Utrecht (Dr. Hemmes), and Brussels (Dr. P. Recht). Presidents of Honour were Professor Kling (Sweden) and Dr. L. Laruelle (Belgium). According to Lépine, the studies and theories of Kling played an important role at the beginning of the renewal of concepts of epidemiological and experimental data on polio, and Dr. Laruelle's audacious initiatives were the key to finally achieving the creation of the European Association against Poliomyelitis 65.

We can observe a trend in the selection of the topics covered at the different Symposia. The first (1953), devoted to the severe Copenhagen polio epidemic and active and passive methods of immunization, also provided a bibliography published in English, French and German. The number of participants in the first and second Symposia was very limited in comparison to the attendance at the following Symposia. The importance and severity of this epidemic meant that the main topics were the description of the epidemic and its different epidemiological, clinical and therapeutic aspects, with special mention of the above-mentioned approaches to solving the severe respiratory difficulties. A lack of knowledge on some key features of polio and the ways to combating it became clear during the discussions on the Copenhagen epidemic; the need was also revealed for a closer study of the problem in an organised, scientific and standardised manner to permit comparisons of date from different countries. The examination of active and passive immunization methods made by professor P. Lépine of the Institut Pasteur of Paris demonstrated the development of passive prophylactic measures from 1910 onwards and the importance of the introduction of gamma-globulin in 1950 by the American, William Hammon. As Lépine explained, he and his collaborators had used it extensively under the auspices of the National Foundation for Infantile Paralysis, and had noted the success of this method 66. He reviewed the history of the active prevention of polio, mentioning the three possible methods for obtaining the vaccine; he acknowledged that some technical problems remained, but he was confident that a vaccine could be available in the near future 67. However, after the interesting debate that followed Lépine's presentation, the European Association concluded that "it would be premature to formulate any opinion regarding the value and practicability of vaccination against poliomyelitis in the present state of knowledge", and it recommended "that member countries should carry out, within the limits of their means, scientific and well controlled trials of these methods" 68.

The topic of the second Symposium (1954) was hospitalization from all points of view and perspectives, with special attention to treatment in the acute stage. For the first time, there was a WHO delegate, Dr. A. Payne, from the Division of Communicable Disease Services 69. There were four sessions dedicated to examining the different problems related to the hospitalization of polio patients in the acute stage. A total of eight points were discussed: the characteristics of the poliomyelitis hospital centre and its place in the general hospital organization of each country; technical and material equipment; medical staff, nurses and auxiliaries; the functioning of the service; hospital epidemiology; precautions in the case of an epidemic or exceptional circumstances; social services for polio patients, and medical and social links; and the role of the hospital as a centre for scientific research and specialized training 70. One of the key points was whether polio patients in the acute stage should be hospitalized in a special hospital for polio victims or in a specialized department of a general hospital. The latter course was supported by Robert Debré, president of the French Institut National d'Hygiène, creator of the University hospitals and responsible for French hospital reform, X. Leclanche and S. Thierry 71.

At the third Symposium (September of 1955), which was once again attended by Dr. Payne, the WHO delegate 72, the question of anti-poliomyelitis vaccinations was raised for the first time. The early vaccination experiences of some European countries (Sweden, Denmark, Germany... ) were presented, as well as the results of the first studies on the degree of anti-poliomyelitis immunity of Italian and Belgian populations 73. The brilliant and fascinating speech by Lépine (Le problème des vaccinations antipoliomyélitiques et l'appréciation du niveau d'immunité des populations) provided the general framework for the presentation of particular European cases 74. The great importance acquired by vaccination and the subsequent debate led to the constitution of a limited commission to set down conclusions derived from the different opinions 75. This symposium was also devoted to the analysis of the different treatments of poliomyelitis in the acute stage, which were studied in all their complexity (the prevention of deformities 76, role of aggravating factors, weaning from the iron lung and mechanical breathing apparatus).

At the fourth Congress (1956), the main topics were: anti-polio vaccination, outbreaks resembling polio, re-education in walking and the organisation of a re-education centre, which for the first time played a central role. The great majority of the sessions were devoted to this subject, and the results of the Symposium, which now had some 200 delegates from 22 different countries. were compiled in a book entitled "Re-education in walking after poliomyelitis", 77. These same topics were the key points of the fifth Symposium (1958), although polio vaccination regained its prominence 78, and retained it until the eleventh Symposium (1966), although it was becoming progressively more complex. In the fifth Symposium (Madrid, 1958), the WHO was represented not only by Dr. Payne but also by the Spaniard Dr. F. Pérez Gallardo, as delegate of the Europe Regional Office 79.

For the first time, vaccination by attenuated living viruses was one of the key points of the sixth Symposium (1959), in which Albert Sabin spoke on the "Present status of field trials with an oral, live, attenuated poliovirus vaccine" 80, which was a summary of the article he had published in the JAMA in June of the same year. From the sixth Symposium onwards, we can see the presence of a "Virological Group" as well as an "Orthopaedic Group", together with a more important role for respiratory disorders. These tendencies continued in the seventh (1961) 81 and eighth (1962) 82 Symposia, when the different aspects of vaccination and virological problems became the key points, relegating physiological and clinical problems to a secondary role. As we shall see, the importance acquired by virology was also evidenced by the incorporation of Spanish groups from the National Virus Centre, who made some excellent contributions in the eleventh Symposium 83.

5.1 Spanish participation

There was an official Spanish delegation (including Bosch Marín) from the second Symposium onwards. Bosch Marín was elected as one of the Vice-Presidents of the Association at the General Assembly of 1 October 1955. He was chosen as delegate due to his position as Director of Central Services of Infant Hygiene of the General Board of Health of the Interior Ministry. From the fifth until the ninth Symposia, Bosch Marín reported data on poliomyelitis morbidity and mortality in Spain and on the different measures adopted (or rather planned to adopt) in our country against the disease and its after-effects. In the eleventh Symposium (1964), the official Spanish delegation was chosen from among polio experts of the National Virus Centre (Centro Nacional de Virus de Majadahonda) of the General Board of Health. This change showed the importance acquired by experts and virology in the fight against poliomyelitis.

Spanish scientific participation started at the third Symposium (1955) with the neurologist Sales Vázquez and the paediatrician M. de la Iglesia from the Paediatric Clinic of the University of Barcelona, who recounted their experience with the treatment of poliomyelitis in the acute phase and with hibernation and neuroplegic drugs during the 1954 epidemic in Catalonia 84. No paper was presented by a Spaniard at the fourth Symposium. Spanish scientific participation took on greater importance at the fifth Symposium in Madrid in 1958. Indeed, as might be expected, this was the Symposium with the greatest Spanish participation, and it was extensively covered by the press, especially the Madrid press 85. Their contributions centred on the prevention of deformities and different aspects of the rehabilitation of polio victims and were reported with all of the other contributions but in a separate volume 86. This Symposium was attended by: physicians from the National Hospital for Infectious Diseases, J. Torres Gost, Director, J. Figueroa Egea, Clinical Head and J. Salvia Torres, Intern; traumatologists Bernardo E. Múgica from the Hospital de la Paz (Madrid), Álvaro López Fernández and José E. Ba-taller Sallée from the National Maritime Sanatorium "La Malvarrosa" ( Valencia) and Vicente Sanchis Olmos; surgeons Francisco Martín Lagos, Professor of the Medical Faculty of Madrid and J. Trochuelo Negrete from the Hospital-Asylum of San Rafael; rehabilitation specialists R. Sales Vázquez and C. Ballús Pascual, from the Department of Poliomyelitis Rehabilitation of the Provincial Office of Health, Provincial Clinical Hospital of Barcelona; Heliodoro Ruiz García, Director of the Cabinet of Physical Medicine and Re-education of Madrid; the Paediatric Professor C. Laguna, Member of the Foundation for the Fight against Poliomyelitis and Director of the National School of Puericulture (Madrid); and Dr. Martín Ongil González, Service of General Medicine of the Compulsory Health Insurance of Madrid 87.

The Sixth Symposium was attended only by the neurologist R. Sales Vázquez and by L. Portal from the Centre for Poliomyelitis Rehabilitation of the Provincial Office of Health, Faculty of Medicine and Clinical Hospital of Barcelona. The former also took part in the seventh Symposium. There was no Spanish presence in the scientific sessions at either the eighth or ninth Symposia. At the tenth Symposium (1964), Drs. F. Pérez Gallardo, L. Valenciano and J. Gabriel y Galán from the National Virus Centre of Madrid presented the results of the first mass vacination campaign against poliomyelitis with Sabin's oral vaccine, which had taken place between the end of 1963 and the spring of 1964 88. Drs. L. Valenciano, J. Gabriel y Galán and F. Pérez Gallardo from the National Virus Centre of Madrid presented an interesting new study on the epidemiology of poliomyelitis in Spain during 1965 and the first six months of 1966 at the eleventh Symposium (1966) 89.

Apart from the special case of the fifth Symposium, when there were more Spanish participants from different specialities such as Paediatrics, Rehabilitation, Surgery, and General Practice, the Spanish presence in European Symposia was consistently provided by representatives from Surgery and Rehabilitation and, until the tenth Symposium, from Paediatrics. At that point, the presence of researchers from the National Virus Centre (Majadahonda) led to some extremely modern and professional papers, which were very different from the contributions made by Bosch Marín from the middle of the 1950s until 1963.

 

6. Concluding remarks

Polio, as an important and worrying worldwide problem, was included in the international public health agenda from the 1940s onwards. The main sources for the study of the contents of polio-related international health policies are the World Polio Congresses, the Reports of the Expert Committee on Poliomyelitis of the World Health Organization and the Symposia promoted by the European Association against Poliomyelitis. The International Polio Conferences were funded by the National Foundation of Infantile Paralysis, a very important private organization promoted by President Roosevelt of the USA. In the case of European conferences, they retained the prototype profile of an association of scientists interested in sharing their experiences and research.

The connection of the WHO with European and worldwide initiatives was evident from the very beginning of their operations, which had the support of the WHO. This explains why, despite the diverse origins and aims of the organisations (although they shared the common goal of the highest possible level of international coordination in the struggle against polio), the degree of synergy among them was considerable. Several leading experts were present in the activities of all three, including the virologist Lépine, the epidemiologists Payne and Albert Sabin, and the Spanish epidemiologist and virologist Pérez Gallardo.

Parallel trends can be observed over this period in the topics considered by the three organizations: from general epidemiological aspects at the first meetings, which sought to establish the dimensions of the polio problem worldwide, to updating delegates on virological and immunity research. The number one subject from the mid-1950s was undoubtedly the two aspects of vaccination: 1) the debate on the advantages and drawbacks of the two main types: Salk's inactivated polio vaccine (IPV) and Sabin's live attenuated vaccine (OPV), and 2) the experiences of mass immunization with either vaccine in different countries. Other questions, such as treatment in the acute phase, physical therapy, orthopaedic apparatus and rehabilitation from sequelae, also found their place on the agenda of international organisations and meetings.

In terms of Spanish participation in the international arena, Spain was completely absent from the WHO until 1958, although the recommendations of the experts were widely quoted by health authorities and professionals and researchers. Moreover, the organisation did on occasions have delegates acting as advisers in Spain.

In the case of the International and European congresses, there were three types of participation. The first was more political: the primary aim was to win points for an unpopular totalitarian regime in the international community by reporting activities and results that often existed only on paper and did not reflect reality, e.g., on the number of iron lungs in Spain or the number of children vaccinated, very difficult to verify, and on the types of campaign. The second involved paediatricians, orthopaedic experts, and rehabilitation professionals who described their experience in the treatment of polio and its sequelae. Most of these professionals were involved in the implementation of the different services created by the Dirección General de Sanidad (General Health Department), the Compulsory Health Insurance Scheme or the hospitals run by religious orders to deal with the problem of polio in Spain. Finally, there was the high-level scientific participation of researchers connected to leading groups in the international arena in the fields of virology and epidemiology, such as the National Virus Centre group or the Sanchis-Bayarri team in Valencia.

The more political profile of the 1940s and 1950s changed from the 1960s onwards, coinciding with the political and social transformations and economic improvements in Spain 90. It reflected the standards of professional scientists with a prestigious technical profile who announced their results in international forums as experts, ignoring all national political connotations. Without the information which may be provided by ongoing research, we may state that the participation of experts in the international forums studied here may be considered to have a double purpose: support and legitimization of the dictatorial political regime, but also an opportunity for these experts to obtain international backing and recognition, paving the way for them to achieve improvements in their own country. A clear example of this double role was that of Florencio Pérez Gallardo: he served the regime as a member of the official delegation to the Second International Conference (1951) but he also received international recognition, as WHO delegate at the V Symposium (1958) and later as Spanish representative to the European Association against Poliomyelitis, which led to improvements in his Virology Laboratory in the National Health School 91.

9. As has recently been pointed out by Axelsson, the prevailing current explanation for the transformation of polio from an uncommon disease to a feared epidemic emphasizes the importance of improvements in hygiene and sanitation. Before the late 19th century, all infants were exposed to the common virus but maternal antibodies that led to lifelong immunity against polio protected them. However, sanitation improvements in some western countries provided a healthier environment and made the virus less common. Consequently fewer infants were exposed to the virus. This increased the proportion of unexposed individuals susceptible to polio later in life. Moreover, improvements in hygiene were most often initiated in areas of relatively high living standards. This made the higher social classes those most susceptible to the virus. For this reason, polio was considered a disease caused by civilization. Axelsson, Per. Hóstens spóke.
