Vaccination is generally allowed during menstruation, but it is recommended to postpone vaccination for those who are obviously weak or have severe menstrual cramps and other related discomforts. According to the vaccination guideline, menstruation is not a contraindication to vaccination, so if there are no other signs of discomfort or acute infections that contraindicate vaccination, vaccination can be given during menstruation. However, in some cases, menstruation may lead to physical weakness. If there is obvious physical discomfort or severe menstrual cramps and other related symptoms, the symptoms may be more prominent in the event of an adverse reaction after vaccination with the vaccine. Therefore, for safety reasons, it may be appropriate to postpone vaccination. Therefore, you should assess your health condition when you have menstruation and consult the vaccination center to make a final decision on whether or not to receive the New Crown vaccine.
