Objective: To perform a cost-effectiveness analysis of pediatric pneumococcal vaccination in Spain. Methods: A deterministic population-based model in the form of a decision-tree with a 1-year time horizon was used to estimate the impact of vaccination with Synflorix^® or Prevenar13^® in children aged less than 2 years in Spain from the perspective of the National Health System. Epidemiological data were obtained from the hospital discharge minimum data set (MDS) and the literature. Data on costs were obtained from national health costs databases. The main outcomes measured were the number of cases avoided of invasive pneumococcal disease, acute otitis media (AOM) and myringotomies, and hospital admissions for pneumonia. All costs were expressed in 2010 euros. Effectiveness was measured as the number of quality-adjusted life years (QALYs) gained. Results: The efficacy of Synflorix^® in preventing episodes of AOM caused by non-typeable Haemophilus influenzae could lead to additional prevention of 41,513 episodes of AOM, 36,324 antibiotic prescriptions and 382 myringotomy procedures and 143 QALYs gained compared with Prevenar13^®. The total vaccination cost with Synflorix^® would result in savings of 22 million euros. Conclusions: Pneumococcal vaccination with Synflorix^® in comparison with Prevenar13^® in children aged less than 2 years old in Spain could achieve a higher number of QALYs and a substantial cost offset. Vaccination with Synflorix^® would be a dominant strategy in terms of cost-effectiveness.
