Childhood vaccine
HPV Vaccine
The HPV vaccine protects against the human papillomavirus, which causes almost all cervical cancers and several other cancers. It is offered to young people and is highly effective.
What it protects against
It protects against the high-risk types of HPV responsible for nearly all cervical cancers, plus some other cancers (including anal, penile, and mouth and throat) and genital warts.
Who it's for
In the UK it is offered to boys and girls in their early teens, and to some other groups. It works best given before any exposure to the virus.
How it works
The vaccine prompts immunity to the main cancer-causing HPV types, so the body clears them before a persistent infection can develop. Combined with cervical screening, it is dramatically reducing cervical cancer.
Safety
Safety and side effects
The HPV vaccine has a strong safety record worldwide. Side effects are usually mild, such as a sore arm.

Answers
HPV Vaccine: frequently asked questions
Why is the HPV vaccine given to boys too?
HPV causes cancers and warts in all genders (including anal, penile and throat cancers), and vaccinating boys also reduces spread — so it is offered to both boys and girls.
Do I still need cervical screening if I had the HPV vaccine?
Yes. The vaccine prevents most, but not all, cervical cancers, so screening when invited remains important for full protection.
