People who have had COVID-19 can still benefit from getting vaccinated due to the severe health risks associated with the virus and the fact that re-infection is possible. There is currently insufficient exact information available to say if or how long people are protected from getting COVID-19 after they have had it. Early evidence suggests natural immunity from COVID-19 lasts for a couple of months and that the vaccine offers better protection than natural immunity. If you are unsure whether or not you ever had COVID-19, the vaccine is still recommended.
