La vacuna contra el sida Aidsvax resulta ineficaz en la mayor parte de los casos, según los primeros estudios realizados a gran escala por la sociedad de biotecnología californiana VaxGen, cuyos resultados ya se han hecho públicos.
Los resultados "no demuestran una reducción estadísticamente significativa de la tasa de infección por el VIH en el conjunto de la población estudiada", explica la compañía. La vacuna se administró a 5.400 voluntarios, sobre todo varones homosexuales de Estados Unidos, Canadá y Europa.
A pesar de su ineficacia en la mayoría de los sujetos, la investigación demostró una reducción significativa estadísticamente de la infección por el VIH en algunas minorías étnicas, sobre todo en la comunidad negra, según informa VaxGen.
El creador de la vacuna, Phillip Berman, responsable de VaxGen, asegura no saber "por qué ciertos grupos de población tienen una respuesta inmunitaria mejor".
