Many Americans who have chosen not to get one of the experimental COVID-19 vaccines because of the risks have hoped that testing positive for antibodies could substitute for being vaccinated, providing a virtual “vaccine passport.”
But the Food and Drug Administration issued guidance this week stating a vaccine is still needed to confirm immunity from the COVID-19 virus.
The FDA acknowledged that antibody tests “can play an important role in identifying individuals who may have been exposed to the SARS-CoV-2 virus and may have developed an adaptive immune response.”
“However, antibody tests should not be used at this time to determine immunity or protection against COVID-19 at any time, and especially after a person has received a COVID-19 vaccination.”
The FDA said that antibodies provided by the vaccines are superior to the antibodies developed from being infected by the virus, providing needed protection that the regular antibodies do not.
But that’s contradicted by empirical study data, Yale University epidemiologist Dr. Harvey Risch told WND.
He pointed to a massive study in Israel finding that people who had tested positive for the novel coronavirus in the previous three or more months had at least as much protection against new infection, hospitalization and death as vaccinated people.
“People become immune by surviving infection,” argued Risch, professor of epidemiology in the Department of Epidemiology and Public Health at the Yale School of Public Health and Yale School of Medicine.
