Andrew Badley, M.D., COVID-19 Research Task Force Chair, Mayo Clinic: If you've already had COVID-19, should you still get vaccinated? The answer is yes. Several reasons for that. One is that the duration of immunity that you receive after having COVID-19 disease is variable. Our current estimates are that that goes away over about three months. The vaccine protection can augment that. So our current recommendations are, if you've had COVID-19, wait until you're better and up to about 90 days or three months and then receive the vaccine when you're able to.
