A generationOn the Internet, you can read information about menstrual disorders over and over again Corona vaccination It should have happened. Kate Clancy, an anthropologist at the University of Illinois, was one of the first to say on Twitter that she came earlier and was heavier than usual. Do others feel the same way? The response was huge. Hundreds of women responded on Twitter that they also had menstrual problems.
The health authorities are also interested in this topic now. In Germany, so far, more than 54 million people have received at least one vaccine. It is not clear how many of them are women. By the end of July, the Paul Ehrlich Institute reported about 310 women with menstrual disorders due to vaccination. 368 symptoms are described. Women most frequently mentioned increased menstrual bleeding and inter-menstrual bleeding, as well as irregular, too long, too short, too late or no menstruation, too long or too short periods, or postmenopausal bleeding. As of the fourth week of August, the British Medicines Agency MHRA has received 33,221 reports of various menstrual disorders. So far, the country has vaccinated 47 million women.Safety committee European Medicines Agency EMA discussed this issue at the last meeting in early August. Conclusion: There is currently no evidence of causality. However, EMA has requested further data from vaccine manufacturers. These will be continuously screened and the matter will be further monitored. Kristin Thiele, spokesperson for the Reproductive Immunology Working Group of the German Society of Immunology, said: “I can understand when women have different menstrual periods after vaccination. She is worried.” “But so far, whether The existence of a causal relationship has always been pure speculation.”
Will the vaccine disrupt the hormonal balance?
This is theoretically possible. As early as 1898, an Italian researcher hypothesized that there was a connection between sex hormones and the immune system. He observed changes in the size of the thymus after the rabbit was sterilized. The specific defense of T lymphocytes is formed in the thymus. But it wasn’t until the second half of the 20th century that researchers began to pay more attention to the problem that women are more likely to develop autoimmune diseases.Today, it is well known that estrogen changes the concentration of pro-inflammatory messenger substances. The ratio of lymphocyte types and the ratio of immunoglobulin in the blood of women is different from that of men, and in some cases it is also different. Vaccination reaction. For example, they will produce more neutralizing antibodies after the flu vaccine. Vaccination against hepatitis A and B also seems to be more effective for women, and possibly Covid-19 vaccination. In a study of 3,318 hospital employees, researchers at San Rafael University Hospital in Milan showed that after being vaccinated with the Biontech/Pfizer vaccine, women of all ages produced more antibodies than men.
