The HPV vaccine is designed to provide protection against a prevalent virus known as the human papillomavirus (HPV). HPV exists in over 100 different types, and while most of them cause no noticeable symptoms and clear up on their own, certain strains can lead to significant health problems such as cancer and genital warts. The primary function of the HPV vaccine is to safeguard against the specific types of HPV that are responsible for the majority of these health issues.   Many strains of HPV are transmitted through sexual contact and are strongly linked to most cases of cervical cancer. Additionally, the vaccine is also effective in preventing vaginal and vulvar cancer in women. Furthermore, the HPV vaccine offers protection against other types of cancers, such as anal cancers, as well as mouth, throat, head, and neck cancers, in both women and men.
