You should still get vaccinated to be fully protected against getting COVID-19 again. You can get the vaccination as soon as your isolation is over and your symptoms are gone. You should not get a vaccination while sick or during your isolation period to avoid spreading the virus to others. You can delay vaccination until 90 days after you were diagnosed because you have natural immunity.
