Do I need the vaccine if I have already had COVID-19?

Yes. Having had COVID-19 does not mean you cannot get it again. There is no evidence of any safety concerns from vaccinating individuals with a past history of COVID-19 infection, or with detectable COVID-19 antibody, so people who have had COVID-19 disease (whether confirmed or suspected) can still receive the COVID-19 vaccine when it is their time to do so.
