La investigación, que se publica en "The New England Journal of Medicine" presenta los resultados tras haber vacunado a 40.000 niños de Soweto. Los autores añaden que la vacuna protegió frente al neumococo incluso en niños infectados por el VIH.
La vacuna experimental redujo la tasa de infección en un 83% en el global de niños, y en un 63% entre los infectados por el virus del sida. Se administró a las 6, 10 y 14 semanas de edad, y también disminuyó el número de infecciones resistentes a los antibióticos.
La compañía Wyeth Pharmaceuticales, que fabrica una vacuna contra siete cepas de neumococo, recomendada en Estados Unidos desde el año 2000, es también la que ha desarrollado el nuevo producto contra nueve cepas.
