Una empresa farmacéutica de origen británico, GlaxoSmithKline (GSK), anunció la elaboración de una vacuna para combatir la cepa H5N1 de gripe aviar. Estaría disponible en el mercado en 2007.
Esa vacuna tendría una respuesta más elevada de inmunización con una dosis baja, debido a un ingrediente "auxiliar", que estimularía el sistema inmunológico.
Para su desarrollo se basaron en unas pruebas clínicas llevadas a cabo en Bélgica, en las que tomaron parte 400 adultos de entre 18 y 60 años, indicó la farmacéutica.
La vacuna todavía no tiene la aprobación de la Administración de Alimentos y Fármacos (FDA), ni de la Agencia Europea de Evaluación de Medicinas (EMEA). La empresa farmacológica estima que costaría 5,8 euros la dosis.
