Investigadores de la Agencia Internacional para la Investigación del Cáncer, en Lyón (Francia), han analizado todos los tipos de VPH en un estudio internacional con más de 3.600 mujeres con cáncer de cérvix de 25 países. El 93% de estos casos tenían algún tipo de VPH, aunque el tipo concreto variaba según la localización geográfica.
En todo el mundo, los tipos de VPH ligados de forma más frecuente al cáncer son el 16 y el 18, mientras que siete tipos (16, 18, 31, 33, 45, 52 y 58) totalizan el 87% de los casos en todo el mundo, con pequeñas variaciones según países. Para los autores, crear una vacuna frente a estos siete tipos sería “factible”, aunque reconocen que su coste de producción sería muy elevado. Consideran que, sobre todo para los países en desarrollo, sería más realista y económica una vacuna que contuviera dos (VPH 16 y 18) o tres (VPH 16, 18 y 45).
