After I’ve gotten vaccinated, how long will it take to get immunity?

If it has been less than two weeks since your final dose of COVID-19 vaccine, regardless of your age, you are NOT considered fully vaccinated. Keep taking all precautions until you are fully vaccinated.

The Pfizer and Moderna vaccines both require two doses of the vaccine to reach maximum effectiveness. Even after receiving your second dose, you will not be immediately protected from COVID-19. Studies show that it takes about one to two weeks after your last dose for your body to be able to protect itself against illness.

The Johnson & Johnson vaccine takes about two weeks after your first and only dose.
