Israeli research finds COVID-19 antibody levels differ between men and women

A new study conducted in Israel finds that antibody levels change according to age and biological sex, with men and women developing more or less of the virus-busting proteins at different stages of their lives, Tel Aviv University says in a statement.

The joint TAU and Shamir Medical Center (Asaf Harofe) research was published last week in the online journal Medrxiv and has not yet been peer-reviewed.

Between November 8, 2020, and March 5, 2021, researchers analyzed 26,170 blood samples collected from those infected with COVID-19, those who were vaccinated against the coronavirus, and unvaccinated people suspected of having contracted COVID-19 but who were asymptomatic.
