The natural immunity provided by COVID-19 infection in unvaccinated adults is on par with protection conferred from vaccines against reinfection with or hospitalization from the virus, a new study reveals. Immunity from COVID-19 was also shown to persist longer than vaccine-induced immunity.

“We found that, before the emergence of the Omicron variant, natural immunity provided a similar degree of protection against COVID-19 infection as mRNA vaccination,” summarized study author Dr. Ari Robicsek.

Dr. Robicsek is the chief medical analytics officer for the Providence health system, one of the largest health systems in the United States, which published the study in collaboration with researchers from the University of Chicago.
