Why are the side effects of corona vaccines more severe in women?

Experts say estrogen triggers a stronger immune response in women than vaccination. “Women have more side effects than men with COVID-19 vaccines than men,” say CDC researchers.

Experts say this is not uncommon in vaccinations, as estrogen in women’s bodies is designed to trigger a stronger immune response. They add that women still receive the corona vaccine because the potential consequences of the disease are much worse than the side effects of the vaccine.

Shelley and Scott Bloomgren, members of the U.S. medical staff, were among the first to receive the Corona vaccine in the United States in January. After the second injection of the Morena vaccine, it was clear to Shelley that he and Scott had significantly different reactions to the vaccine. In fact, Scott was fine, but Shelley had body aches and problems such as fever and chills and extreme tiredness. After two days, the symptoms disappeared.

In many cases, this experience seems to have been repeated by a credible source published by the Centers for Disease Control and Prevention (CDC). . In fact, 79% of side effects have been reported by women, although only 61% of vaccines have been given to women.

This seems to be a common occurrence in the results of studies by infectious disease specialists. They point out that for years there has been a more severe reaction from women to other vaccines. the reason? Experts believe that in women, especially in postmenopausal women, estrogen levels help activate the immune response to the disease and therefore vaccines.

Men, on the other hand, have more testosterone, a hormone that can reduce or slow down the same response to some extent. Simply put, women generally react more strongly to vaccines because their bodies are faster and stronger when the vaccine is activated.

“The severity of infectious diseases is generally always related to the immune response, and in women, there is a stronger and more responsive response (to many vaccines) to fever vaccines,” said Larry Schlesinger, president and executive director of the Texas Institute for Medical Research in San Antonio. Jaundice, DPT, influenza and other diseases have also been seen and studied more severely in women. Estrogen encourages the body to produce more T cells (our protective reactor cells) when the vaccine is produced, so we see a rapid and strong response from many women. 》
