Pregnancy is not recommended during HPV vaccination, but only after 6 months of having received all three doses of the vaccine. HPV infection is necessary for the development of cervical cancer, and 99% of cervical cancer patients have HPV infection, so preventing HPV infection can prevent cervical cancer to some extent, and HPV vaccine is the means to prevent HPV infection. There are three types of HPV vaccines that have been marketed, namely bivalent, quadrivalent and nine-valent. The HPV vaccine is a vaccine made of inactivated virus that stimulates the body to produce antibodies against HPV virus to prevent HPV infection. Theoretically, pregnant women can receive the HPV vaccine during pregnancy, but there is no experimental data or scientific research to prove that there are no side effects of HPV vaccination during pregnancy, so for insurance reasons it is not recommended that pregnant women receive the HPV vaccine during pregnancy. Therefore, if you become pregnant during HPV vaccination, you need to suspend HPV vaccination and wait until you have given birth. In general, pregnancy is not recommended within 6 months after the full HPV vaccination, and pregnancy during HPV vaccination needs to be suspended.
