Why is HPV vaccine recommended for girls 11 to 12 years of age?
It is important for girls to get HPV vaccine before they become sexually active. The vaccine is most effective for girls/women who get vaccinated before their first sexual contact. It does not work as well for those who were exposed to the virus before getting the vaccine. However, most women will still benefit from getting the vaccine because they will be protected against other virus types contained in the vaccine.
