Cervical cancer vaccine quadrivalent is given to women between the ages of 20 and 45 years old and requires three doses, one in the zero month, one in the second month and one in the sixth month. The HPV vaccine is not a substitute for routine cervical cancer screening, and regular TCT and HPV checkups are required. No adverse effects of HPV vaccine on the fetus have been found, therefore, after vaccination, pregnancy is found to continue as long as re-vaccination is stopped and pregnancy can be considered.
