The HPV vaccine is a vaccine designed to protect against the human papillomavirus, which can lead to certain types of cancer, including cervical cancer. It is recommended for preteens, but can be given to individuals up to age 26. The vaccine works by helping the body develop immunity to the virus. Receiving the HPV vaccine can significantly reduce the risk of developing HPV-related cancers and genital warts. It is typically administered in a series of two or three shots, depending on the age of the recipient. Health organizations encourage vaccination as a key preventive measure.
