El número de vacunas disponibles para prevenir enfermedades, en la actualidad unas 20, se habrá duplicado en el plazo de una década, según estima la Organización Mundial de la Salud (OMS).
La organización señala que en estos momentos están en desarrollo un buen número de vacunas que protegen contra un amplio abanico de enfermedades infecciones a menudo mortales. Entre ellas cita vacunas contra la meningitis, la malaria y el cáncer de cuello uterino.
La OMS resalta la labor de varias compañías farmacéuticas –GlaxoSmithKline, Sanofia-Aventis o Merck & Co.- que están revitalizando el sector y cuentan con productos experimentales muy prometedores.
Para la Dra. Marie-Paule Kieny, responsable de investigación de vacunas de la OMS, se necesita hacer mucho más para asegurar que estos novedosos tratamientos preventivos sean accesibles a las personas que los necesitan en todo el mundo. Esta especialista añade que los tiempos actuales son muy prometedores en relación con el desarrollo de vacunas. "Varios productos nuevos estarán pronto disponibles y, en conjunto, podrán proteger millones de vidas", comentó en una conferencia celebrada en Brasil.
