There are three main types of HPV vaccines that are currently available: bivalent vaccine, quadrivalent vaccine and nine-valent vaccine, and they have different age ranges. The bivalent vaccine is suitable for women aged 9 to 45 years old; the quadrivalent vaccine is suitable for ages 20 to 45 years old; and the nine-valent vaccine, the age of vaccination is suitable for ages 16 to 26 years old. Patients can choose the appropriate vaccine to be injected according to their age range, and women who do not have a sexual life will have the best results with the injection. Women who have sex need to pay attention to two aspects before the injection: 1. Patients need to be checked regularly for HPV virus before and after the injection to observe whether there is infection. 2. Women who cannot exclude pregnancy must undergo pregnancy-related screening, because patients cannot inject the vaccine after finding pregnancy, or in the process of injection, without good contraception, have found pregnancy If the patient is pregnant, the injection should be stopped immediately and the remaining injections should be completed after the birth.
