Coronavirus: Until when are antibodies produced?

Coronavirus: Until when are antibodies produced?

What the findings of a Greek researcher say about the production of antibodies after the initial coronavirus infection.

Patients with Covid-19 develop high-quality antibodies to the SARS-CoV-2 coronavirus as long as five to seven months after the initial infection, according to a new US study. The study shows that those who become infected with the new virus may – although not necessarily – develop long-term immunity.

Researchers at the University of Arizona School of Medicine, led by Associate Professor of Immunology Dipta Batatsaria, who published the study in the journal Immunity performed antibody tests on 5,882 people and found that antibodies were present in their blood at adequate levels for at least five to seven months.

The Research from the University of Arizona

“Many concerns have been expressed about the duration of immunity to Covid-19. “We have clearly found that high-quality antibodies continue to be produced five to seven months after infection,” Batatsaria said, which is very encouraging for future vaccines. He also said that pessimistic estimates that antibody levels in the body are declining rapidly and that coronavirus immunity does not last long are wrong.

 

The findings of a Greek researcher

Two similar studies, one from Harvard University School of Medicine and another from the University of Toronto, in a total of nearly 750 people infected with the coronavirus, published in another journal of Immunology, Science Immunology, found that patients continued to have sufficient antibodies to provide them with immunity after three months. In particular, IgC antibodies against the coronavirus spike protein were found to last more than 100 days.

Finally, another study, led by a Greek researcher, Dr. Theodora Chatziioannou of Rockefeller University in New York, who analyzed 37 blood samples, concluded that antibodies to seasonal coronaviruses (which cause the common cold) do not provide protection against severe Covid-19 infection.
