There is no clinical data to suggest that vaccination of women during menstruation will affect the immune effect or induce serious abnormal reactions after vaccination, and there is no contraindication to the vaccination of women during menstruation, so vaccination of New Crown can generally be given during menstruation. Although vaccination is possible, since a woman’s physical condition may decline during menstruation, the incidence of adverse reactions may be increased by vaccination with the New Crown vaccine at this time, and if it is not particularly urgent, the menstrual period can be avoided. In addition, if menstruating women feel significant discomfort, it is recommended that the vaccination be postponed until the discomfort subsides or the menstrual period has passed. Because some people may experience local or general discomfort after vaccination, such as nausea, vomiting, dizziness, weakness, fever, etc., and some women are in poor overall condition during menstruation, often accompanied by dizziness, loss of appetite, abdominal pain, back pain, weakness, and even low-grade fever, which may aggravate or cover up the adverse reactions after vaccination with the new crown vaccine, which is not conducive to the judgment and treatment of this group of people. The vaccination can be suspended until the discomfort is relieved and then the new crown vaccination can be administered. As mentioned above, menstruation does not affect the vaccination of women, and the onset of menstruation does not affect the effect of the vaccination, nor does the vaccination affect the volume of menstruation and menstruation. If the vaccination is completed during menstruation and there are no uncomfortable symptoms, there is no need to worry about it, but if there are uncomfortable symptoms, you need to go to the hospital in time. After vaccination, ensure sufficient rest, avoid straining, keep the vaccination site clean and dry, and develop good hygiene habits.
