The quadrivalent HPV vaccine is a vaccine to prevent the occurrence of multiple HPV infections, including two high-risk HPV types, 16 and 18, and two low-risk HPV types, 6 and 11. High-risk virus infections can easily lead to cervical cancer, so the vaccination can effectively reduce the probability of developing cervical cancer. HPV is a relatively common reproductive system infection in women, which can lead to cervicitis and even tumors of the reproductive system, so vaccination can be given if available. The quadrivalent HPV vaccination covers a wide range of ages, and can be administered to women who are sexually active up to the age of 45. In addition to vaccination, it is important to pay attention to sexual hygiene and avoid multiple sexual partners to prevent the possibility of cross-infection. Regular gynecological examinations and, if necessary, cervical cytology are also required.
