Israeli study finds effects of COVID-19 vary between men and women

The study, published in Medrxiv, used more than 26,000 blood samples from recovered, vaccinated and unvaccinated coronavirus patients.

In the study, a difference in the concentration of antibodies in the blood was found between the vaccinated men and women.

In women aged 51 and over, the level of antibodies found was higher than in men of the same age. The study explained this by stating that it could be linked to the level of estrogen hormone in women of these ages.

Additionally, a higher concentration of antibodies has been found in women as they get older from the age of 51, although an increase in antibodies in men can be seen from an earlier age. ‘about 35 years old.

More notable trends found in the study include that people who received two doses of the COVID-19 vaccine have four times the amount of antibodies of people who have recovered from the virus, and a stronger immune response in general.

A high concentration of antibodies in young adults is most often the result of a strong immune response, which contrasts with the same phenomenon seen in the elderly, which indicates an overreaction of the immune system, associated with serious diseases.

The study, led by Professor Noam Shomron of TAU’s Computational Genomics Lab and Dr Adina Bar Chaim of Shamir Medical Center, concluded that while more research is needed, they hope the correlation of vaccine effectiveness with age and gender can be proven using reliable measurement in the future.
