Newly Released Study Finds Nearly Everyone Who Recovers From COVID-19 Makes Coronavirus Antibodies

A recent study published in Nature Medicine offers new hope regarding the benefits of antibody testing for SARS-CoV-2. Researchers in China drew blood from 285 people hospitalized with severe COVID-19. After analyzing those samples, scientists found all had developed SARS-CoV-2 specific antibodies within two to three weeks of their first symptoms. The findings suggest the immune systems of people who survive COVID-19 have been primed to recognize SARS-CoV-2 and possibly thwart a second infection.

To confirm their results, the researchers focused on 69 additional people diagnosed with COVID-19. With this group, they collected blood samples from each person upon admission to the hospital and every three days until discharge. The research team found that, with the exception of one woman and her daughter, the patients produced specific antibodies against SARS-CoV-2 within 20 days of their first symptoms of COVID-19.

NIH Director Dr. Francis Colins covered the study in his blog which can be found here.
