HPV vaccine injection during menstruation may cause harm, mainly women during menstruation body resistance is relatively low, injection of HPV vaccine will show a greater chance of allergic reaction. Because people's resistance is different, showing the probability of allergic reaction is different, patients in the body resistance is low easy to show allergic reaction. For example, in clinical practice, some patients are not allergic to cephalosporins for many times, and occasionally they will show allergic reactions once, which may be related to the batch of drugs, and most importantly, to the body's resistance. If the patient has been vaccinated during menstruation and does not show obvious allergic reactions, this situation is not any problem.
