Periods of menstruation, generally referred to as a woman’s menstrual period, can usually be vaccinated with the New Crown vaccine. Menstruation is not a contraindication to vaccination with the new crown vaccine, and patients are usually able to receive the new crown vaccine if they are not experiencing menstrual discomfort. If the patient has obvious menstrual discomfort, it is recommended that the vaccine be withheld to avoid confusion between menstrual discomfort and adverse reactions to the vaccine. 1. Able to receive the new crown vaccine: During the physiological period of women, some foods or drugs may affect menstruation to a certain extent, but the side effects of the new crown vaccine are not significant. If there is no menstrual discomfort, the patient is usually able to receive the vaccine. 2. Withhold the vaccination: If the patient has severe discomfort such as menstrual cramps, nausea and fatigue during the physiological period that requires vaccination, it is recommended that the vaccination be withheld. Because after vaccination, some adverse reactions may occur, aggravating the discomfort, and it is not possible to determine whether it is the discomfort of menstruation or the adverse reactions caused by vaccination with the New Crown Vaccine.
