Hospital Staff With Coronavirus Developed Protective Antibodies, Study Reveals

A new study reveals that the majority of nurses and doctors who worked with COVID-19 patients and gotten themselves infected were shown to produce antibodies that possibly protected them from getting reinfection, creating some sort of herd immunity for healthcare workers.

Study Reveals Hospital Staff Developed Antibodies To Stop COVID-19 Reinfection

As per a new study conducted by the Institut Pasteur and university hospitals in Strasbourg, nearly all of the doctors and nurses who got infected with the coronavirus at a hospital in northeastern France were shown to develop antibodies against it, which possibly served as a sort of shield that stopped them from getting reinfected. The participants, all of which recovered from mild forms of PCR-confirmed SARS-CoV-2 infection, were then tested for anti-SARS-CoV-2 antibodies via two ways: the S-Flow assay and a rapid test.

However, the study, which evaluated some 160 doctors and nurses, hasn’t undergone any peer review as of now.

Per Bloomberg (which first reported the study), only one person out of the 160 participants did not develop antibodies within 15 days after the infection started. Overall, however, 98 percent of the health workers managed to develop antibodies that can help them neutralize the virus after just 41 days of observations.

“This finding supports the use of serologic testing for the diagnosis of individuals who have recovered from SARS-CoV-2 infection,” the researchers wrote in their study.

Per the team behind the research, this new study addresses one crucial question when it comes to the new virus, which is whether people who got infected with COVID-19 (especially those who managed to recover after avoiding becoming severely ill) can develop the necessary antibodies that are strong enough to protect them from getting reinfected with the virus.

“We further report that the neutralization activity of the serum increases with time, reaching 97 percent four weeks after the onset of symptoms. Therefore, it is a fair assumption that the majority of individuals with mild COVID-19 generate neutralizing antibodies within a month after onset of symptoms,” the researchers wrote.

The study came after a WHO update that stated there is still no evidence that people who recovered from COVID-19 have antibodies that stopped any reinfection.
