Menstruation is also known as menstruation, and women who do not have a clean period can also receive the vaccine. There are no contraindications for the vaccine, and menstruation basically does not have a significant impact on the effectiveness of the vaccine or on the body of the vaccinated person. The vaccine mainly works on the immune system of the human body, and produces immune resistance to the virus through constant stimulation of the immune system. Menstruation, on the other hand, is the body’s endocrine system, which is regulated by the stimulation of estrogen. The two systems basically function separately and rarely affect each other under normal circumstances. However, women who are vaccinated when their menstrual period is not completely over may experience some nausea, abdominal pain and other uncomfortable symptoms because their bodies are in a special period. Some adverse reactions, such as redness and swelling at the vaccination site, dizziness, etc., may also occur during vaccination with the New Crown Vaccine. Therefore, in order to minimize the discomfort, it is recommended to wait until the menstrual period is completely over before receiving the vaccine if there are no special circumstances. There are some contraindications to vaccination, for example, it is not recommended to vaccinate women who have not had their menstrual period and are in a period of fever, or during an acute attack of an acute or chronic disease. If there is a history of allergy to the vaccine, the vaccine should be checked to determine whether it can be administered.
