July 2021: Shomron: COVID-19 antibodies from vaccination are much higher than from infection

 A new study, led by Guy Shapira, Edmond J. Safra PhD student fellow, and his advisor Prof. Noam Shomron, Edmond J. Safra member (Medicine) and colleagues from Shamir Medical Center (Asaf Harofe), found that the amount of antibodies in recovering COVID-19 patients change according to age groups, gender, symptoms and time elapsed since vaccination.

 

The team assessed COVID-19 antibody levels in more than 26,000 blood samples from vaccinated and unvaccinated people, along with people who had recovered from their COVID-19 infections.

 

Individuals who received two doses of the COVID-19 vaccine had four times the amount of antibodies of people who recovered from the virus, and a stronger immune response in general. The study also found that men and women had different antibody levels after either vaccination or infection. The researchers also found age-related differences between convalescent or vaccinated men and women.

 

The study was published on MedRxiv, a "pre-print" server for health research. It was broadly featured in media in Israel and abroad:

JPOST , TIMES OF ISRAEL , XINHUA , CHINA , ISRAEL3, and more.
