In general, the third shot of the NeoCrown vaccine does not affect menstruation.
The third dose of the vaccine works by activating the body’s immune system, thereby increasing the body’s resistance to the New Crown Virus and reducing the virus’ pathogenicity through active immune cells when exposed to the New Crown Virus.
Menstruation is caused by the shedding of the uterine lining due to the action of estrogen and progesterone. Irregular menstruation is a reflection of the endocrine system and the reproductive system, and has little to do with the immune system. Therefore, the third vaccination will not affect menstruation.
If a woman experiences abnormal menstruation after the third vaccination, it may be due to stress or a combination of endocrine and reproductive diseases, and she needs to go to the hospital in time for a complete examination to clarify the cause of the disease, and if there is any abnormality, it should be treated actively.
