Cleveland Clinic study finds no vaccine needed for those previously infected with COVID-19

Editor's Note

This study by researchers at the Cleveland Clinic finds that those who have been infected with COVID-19 do not get additional benefits from the vaccine, suggesting that vaccines should be prioritized to individuals who have not gotten the infection.

During this analysis of 52,238 Cleveland Clinic employees over a 5-month period, no COVID-19 infections were found in previously infected individuals, with or without vaccination.

A Cox proportional hazards regression model found that vaccination was associated with a significantly lower risk of COVID-19 infection among those not previously infected, but not among those who had been previously infected with COVID-19.

The study shows that individuals previously infected with COVID-19 are unlikely to get COVID-19 re-infection whether they receive the vaccine or not, the researchers say.
