After getting vaccinated, how quickly am I protected?

Immunity, or protection from COVID-19, doesn’t happen immediately. After both doses of the vaccine, it usually takes about two weeks for your body to develop full protection. However, you develop some immunity about two weeks after your first dose.

The Pfizer (Comirnaty) and Moderna (Spikevax) vaccines require two doses to be considered fully vaccinated, with booster shots recommended to maintain your protection over time.

Data also suggests that these vaccines are effective in the short term against the disease and the need for hospitalization starting one to two weeks after a person receives the first dose.
