Throughout the last centuries, the first signs of vaccination were linked to variolation procedures. In 1796, Edward Jenner developed the first vaccine for smallpox: the world eradication of this mortal disease was achieved due to the vaccination. In other diseases, such as neonatal tetanus, poliomyelitis or measles, immunization programmes have drastically decreased morbidity and mortality. Nowadays, these achievements of vaccination have caused a false perception of lack of risk, causing a decrease in immunization coverage in some cases. There has been a considerable increase on reported cases and outbreaks of some diseases such as measles. The messages of anti-vaccination movements have contributed to generate this situation by associating some adverse effects with vaccines, but there is no scientific evidence to support it.
