Vaccine benefits may be diminished in people who have had COVID-19: Study

Research conducted by the Cleveland Clinic found the benefits of vaccinating those who have previously been infected with COVID-19 may be diminished.

A study conducted on over 52,000 Cleveland Clinic employees found little difference in COVID-19 infections between previously infected and currently unvaccinated participants; previously infected and currently vaccinated participants; and previously uninfected and currently vaccinated participants. Researchers also found that 99.3% of all COVID-19 infections occurred in unvaccinated participants who had not been previously infected. The remaining 0.7% of infections were in vaccinated participants who were not previously infected.
