It is possible to receive the third booster shot during the physiological period. The main purpose of the third “booster” dose of the vaccine is to reduce the likelihood of viral infection by rapidly increasing the body’s dwindling neutralizing antibodies, which in turn provide better protection. As the vaccine consists of inactivated, adenovirus-vectored and recombinant protein vaccines, there are no components in these vaccines that may affect the menstrual cycle. For the time being, it is possible to receive the third “booster” dose of the vaccine during the menstrual period. Contraindications to the New Crown vaccine include 1. Hypersensitivity to the active ingredients of the vaccine, to any of the inactive ingredients, to substances used in the production process, or to previous allergies to the same type of vaccine; or previous severe allergic reactions to the vaccine (e.g., acute anaphylactic reactions, angioneurotic edema, respiratory distress, etc.). 2. Those with uncontrolled epilepsy and other serious neurological diseases (e.g. transverse myelitis, Guillain-Barre syndrome, demyelinating diseases, etc.). 3. Those who are experiencing fever, or suffering from acute illness, or acute exacerbation of chronic diseases, or uncontrolled severe chronic diseases. 4. Women during pregnancy.
