Important Facts About the COVID-19 Vaccine

There are three COVID-19 vaccines.

For the two-dose products, you need to get two doses of the vaccine 21 or 28 days apart (depending on which vaccine you get). Both the Pfizer and Moderna vaccines were designed to impart immunity with two doses. You must get two of the same vaccine. There is no clinical evidence as to whether you develop significant immunity after the first dose, so it is important to get the second dose on schedule.

It takes two weeks from your second dose for immunity to develop. Vaccinated persons may still be able to transmit the virus to others. Current vaccine studies were not designed to determine if or how well the vaccines would stop transmission of the virus to others. This is why it is important to continue wearing a mask and practicing social distancing even after you have been vaccinated.
