HPV vaccine cannot be given during menstruation. HPV vaccine is an inactivated viral strain vaccine, which, like other flu vaccines and B-brain vaccines, needs to be avoided during menstruation, avoiding the fever and cold phase, and only when the body’s immunity is relatively strong. Because the body’s resistance and immunity are at their lowest during menstruation, it is easy to have adverse reactions to the vaccine, such as low fever and local redness, infection, and pus flow at the injection site. Therefore, no matter which type of vaccine is given, it is not recommended to give the vaccine when you have your period. It is recommended to give the vaccine only 2-3 days after your period is clean, when your body temperature is normal, and when there are no symptoms such as fever, headache, cold or cough.
