For a long time, scientists drew attention to the fact that the reaction to vaccination in women is many times stronger than in men. This applies to many vaccines, such as measles and polio, influenza and mumps. Real vaccinations against Covid-19 were no exception, but they showed even bigger problems.
Medical experts explained that this is due to the level of estrogen in the woman’s body. Dr. Cherian says on this point:
Testosterone is generally an immunosuppressive hormone and estrogen is an immunostimulant. Thus, the side effects of the vaccine are most pronounced in women during the premenopausal period.
Interestingly, by the way, it has been known for decades that the number of vaccination side effects in women depends on the phase of the menstrual cycle.
In the age of “personalized medicine,” in the light of this kind of research, one would expect doctors to recommend that women vaccinate at this or that phase of the cycle. But for some reason this does not happen. And such studies were completed very quickly.
Apparently, considering that “personalized medicine” should not extend to vaccinations. After all, they are “extremely safe” and “should not have gender differences among the population.”
No less striking were the messages that flooded the worldwide Internet. Unvaccinated women report bleeding and irregular menstrual periods after contact with recently vaccinated men.
So far, scientists are studying how widespread this effect is, and what types of vaccines can cause it. Perhaps this is the real reason for the practical recall of AstraZeneca and Johnson & Johnson. These vaccines are live, and while the people vaccinated with them should not shed the vector virus, in fact, they may still shed it.
It is also worth noting that scientists from the University of Miami have begun to conduct research on the possible effect of the Covid-19 vaccine on male fertility. To maintain fertility, men are advised to freeze their material before vaccination.
