How many shots do I have to get if I want to be protected against COVID-19?


Some of the vaccines that have been authorized by the FDA—including the Pfizer and Moderna vaccines—require two doses three to four weeks apart. It is very important that you get both doses at the recommended times. Others, including the Johnson & Johnson vaccine, require only one shot.

We do not yet know how long the protection from these vaccines will work. It is possible that you will need to get additional shots in the future.
