How many doses of HPV vaccine are recommended for individuals under 15 years old?

The correct answer is that individuals under 15 years old are recommended to receive two doses of the HPV vaccine. This recommendation is based on evidence that this age group mounts a strong immune response after receiving just two doses of the vaccine, which are administered six to twelve months apart.

The two-dose schedule is effective in providing long-lasting immunity against the types of human papillomavirus (HPV) that can cause cervical cancer and other HPV-related diseases. For individuals who start the vaccination series at 15 years or older, a three-dose schedule is recommended due to their potentially weaker immune response.

This approach helps to ensure that preteens and younger adolescents can complete the vaccination in a timely manner, enhancing the overall impact of HPV vaccination programs aimed at reducing the incidence of cervical cancer and other HPV-related conditions.
