Although this vaccine is currently safe and most people do not experience any abnormalities, a very small number of people may experience allergies, fever, redness, swelling, pain, etc. Pregnancy after six months of HPV vaccination is not a good idea. There is a process of reaction in the body after vaccination, and premature pregnancy is not good for the growth and development of the fetus. Moreover, after pregnancy, the body’s resistance naturally decreases, which affects the effectiveness of vaccination and leads to vaccination failure. Three consecutive vaccinations are required, and the whole process lasts for six months. For the sake of the baby’s health, it is necessary to take good contraceptive measures, and it is recommended to count from the time of the last vaccination.
