Brazil’s Health Ministry has extended access to the HPV vaccine for young children who have experienced sexual violence, lowering the age from nine to two, as part of efforts to enhance protection and response to abuse cases.
Brazil’s Health Ministry has widened access to the HPV vaccine for children who have been victims of sexual violence, allowing boys and girls from the age of two to receive a dose after assessment by the reference service or the clinician in charge. The move extends the previous guidance, which began at nine years old, and officials say it is meant to add protection in cases where abuse has already taken place.
The quadrivalent HPV vaccine used in Brazil protects against four virus types: 6, 11, 16 and 18. The ministry says the first two are linked mainly to genital warts and recurrent respiratory papillomatosis, while types 16 and 18 are associated with cancers of the cervix, vagina, penis and oropharynx. Vaccination is still considered most effective before the start of sexual activity, with the routine public programme aimed at children aged nine to 14.
The lower age limit was set because the national immunisation programme already uses the HPV vaccine in children as young as two in another clinical context: recurrent respiratory papillomatosis, a condition that causes lesions in the airways. Health officials also pointed to evidence from a study in Colombia, Mexico and Panama involving 74 girls aged four to six, which found a strong immune response lasting 36 months and no serious vaccine-related adverse events.
Even so, the ministry stressed that an earlier dose does not replace the routine schedule. Children who receive the vaccine before nine will still need to be vaccinated again in the standard age group, where a single dose is recommended for the general population. For victims of sexual abuse, the ministry’s broader guidance also allows vaccination later in childhood and adulthood, depending on age and clinical assessment.
