Because it is possible to be reinfected with COVID-19, it is important that people who have already had COVID-19 be vaccinated. You may get vaccinated as soon as your isolation period is over, and your symptoms are gone. You should not get vaccinated while sick or during your isolation period to avoid spreading the infection to other people. Because you have natural immunity for 90 days after you test positive, you can wait until those 90 days are over to get the vaccine so the appointment is open for others.
