What Is a Human Papillomavirus Infection?
10. How Does the HPV Vaccine Work?
The HPV vaccine protects against the most dangerous forms of HPV that lead to cancer. It is recommended for children ages 11-12, although it can be given earlier. It consists of two separate injections, administered six months apart. When people in the 15-26 age range are vaccinated, three shots are typically administered with six months between each injection.
Most people over the age of 26 have already been exposed to HPV, so the vaccine is not necessarily as effective. There are some exceptions, however, so talk to your doctor if you believe that you are at heightened risk and want to see if the vaccine could be helpful to you.
