Abstract (English): Objective. In Latin America and the Caribbean, routine vaccination of infants against Streptococcus pneumoniae would need substantial investment by governments and donor organizations. Policymakers need information about the projected health benefits, costs, and cost-effectiveness of vaccination when considering these investments. Our aim was to incorporate vaccine, demographic, epidemiologic, and cost data into an economic analysis of pneumococcal vaccination of infants in Latin America and the Caribbean. Methods. We previously used a structured literature review to develop regional estimates of the incidence of disease. Cost data were collected from physician interviews and public fee schedules. We then constructed a decision analytic model to compare pneumococcal conjugate vaccination of infants with no vaccination across this region, examining only vaccine's direct effects on children. Results. Pneumococcal vaccination at the rate of diphtheria-tetanus-pertussis vaccine coverage was projected to prevent 9 500 deaths per year in children aged 0 to 5 years in the region, or approximately one life saved per 1 100 infants vaccinated. These saved lives as well as averted cases of deafness, motor deficit, and seizure result in 321 000 disability-adjusted life years (DALYs) being averted annually. At vaccine prices between US$5 and US$53 per dose, the cost per DALY averted from a societal perspective would range from US$154 to US$5 252. Conclusion. Pneumococcal conjugate vaccine was highly cost-effective up to $40 per dose. Introduction of pneumococcal vaccine in the Latin American and Caribbean region is projected to reduce childhood mortality and to be highly cost-effective across a range of possible costs.

Abstract (Spanish): Objetivo. En América Latina y el Caribe, la vacunación sistemática de niños contra Streptococcus pneumoniae podría requerir inversiones considerables de los gobiernos y organizaciones donantes. Al evaluar estas inversiones se requiere información sobre los posibles beneficios sanitarios, costos y rentabilidad (relación costo-efectividad) de la vacunación. Se presenta un análisis económico de la vacunación infantil antineumocócica en América Latina y el Caribe a partir de la información de la vacuna y de datos demográficos, epidemiológicos y de costos. Métodos. Se realizó una revisión bibliográfica estructurada previa para llegar a estimados regionales de la incidencia de la enfermedad. Los costos se tomaron de entrevistas a médicos y tarifas públicas. Se construyó un modelo analítico de decisión para comparar la vacunación de los niños de esta región con la vacuna antineumocócica conjugada y la no vacunación, tomando en cuenta solamente el efecto directo de la vacuna en los niños. Resultados. Se proyectó la vacunación antineumocócica con las tasas de cobertura de la vacuna contra la difteria, el tétanos y la tosferina para prevenir 9 500 muertes anuales en menores de 5 años en esta región, o aproximadamente 1 vida salvada por cada 1 100 niños vacunados. Las vidas salvadas y los casos prevenidos de sordera, trastornos psicomotores y convulsiones equivalen a evitar anualmente 321 000 años de vida ajustados por incapacidad (AVAD). A un precio de la vacuna de US$ 5,00 a US$ 53,00 por dosis, el costo por AVAD evitado desde el punto de vista de la sociedad sería de US$ 154,00 a US$ 5 252,00. Conclusiones. La vacuna antineumocócica conjugada fue altamente rentable hasta un precio de US$ 40,00 por dosis. La introducción de esta vacuna en América Latina y el Caribe puede reducir la mortalidad infantil con una alta rentabilidad en un amplio espectro de posibles costos. [ABSTRACT FROM AUTHOR]
