The first dose of the cervical cancer quadrivalent vaccine should be given at whatever time is convenient for you, but it is best to avoid your menstrual period. The second vaccination should be given within 3 months after the first vaccination. The third vaccination should be given within 8 months after the second vaccination, and the three vaccinations should be completed within one year. In addition, patients who are allergic to protein or yeast are not allowed to receive the cervical cancer vaccine, and the cervical cancer vaccine can prevent HPV type 6, HPV type 11, HPV type 18, and HPV type 16 infections, so it is recommended to receive all cervical cancer vaccines if age appropriate.
