The U.S. Food and Drug Administration (FDA) has granted emergency use for two new coronavirus vaccines, one developed by the drug company Pfizer and the biotech company BioNTech and the other by the biotech company ModernaTX. Both are mRNA vaccines and have similar structure.

Can I stop wearing a mask after getting a COVID-19 vaccine?

No. For a couple reasons, masks and social distancing will still be recommended for some time after people are vaccinated.

To start, the first coronavirus vaccines require two shots; Pfizer’s second dose comes three weeks after the first and Moderna’s comes after four weeks. And the effect of vaccinations generally aren’t immediate.
