All girls aged 12 to 13 are offered HPV (human papilloma virus) vaccination as part of the NHS childhood vaccination programme. The vaccine protects against cervical cancer. It's usually given to girls in year eight at schools in England.
The HPV vaccine is delivered largely through secondary schools, and consists of three injections over a period of 12 months.
Research has shown that the HPV vaccine provides effective protection for at least eight years after completion of the three-dose course. It is not known yet how long protection will last beyond this time.
