Anvisa indica vacina contra o HPV para prevenir mais tipos de câncer

Por Paula Laboissière - A Agência Nacional de Vigilância Sanitária (Anvisa) aprovou nova indicação terapêutica para a vacinaGardasil9, que passa a valer também para a prevenção de cânceres de orofaringe, cabeça e pescoço associados ao HPV.

Até então, o imunizante era indicado para a prevenção de cânceres do colo do útero, da vulva, da vagina, do ânus; de lesões pré-cancerosas ou displásicas; de verrugas genitais e infecções persistentes causadas pelo vírus.

A nova indicação foi aprovada paracrianças,homens e mulheres de 9 a 45 anos. A orientação da Anvisa é que a imunização seja feita antes do início da vida sexual, já que o HPV é transmitido por meio de relações sexuais.

A nova indicação é fundamentada na prevenção da infecção persistente pelos tipos de HPV oncogênicos, reconhecidos como principais causadores desses cânceres, bem como na demonstração de resposta imunológica robusta contra esses tipos virais, destacou a agência. (com Agência Brasil)
