COVID-19 Vaccine Frequently Asked Questions
Once a person has been immunized (both shots) and completed self-quarantine following both immunizations, that person is assumed to be successfully immunized. However, while that person may be immune, could that person still be a “carrier” who could infect others?
The phase 3 clinical trials of the vaccine only have looked at the benefit of the vaccine in preventing illness (mild, moderate and severe). They were not designed to provide information on transmission of SARS-CoV-2. Therefore, we do not know whether a vaccinated individual may still have the ability to transmit this virus.

After I get the vaccine, do I still need to wear a mask and social distance?
The vaccine is extra protection, like a super mask, but it is not perfect. Even in very controlled trials, 90-95% of people getting the vaccine were protected from developing COVID-19, so 5-10% still got sick. And out in the world under less perfect conditions, the number of people still getting sick with COVID-19 even with a vaccine could be higher. So yes, after you get vaccinated, you still need to wear a mask, socially distance, and get tested if you think you have symptoms.
This is especially true if you have only gotten one dose of the 2-dose series. At the current moment, there is not enough data to say that one dose will protect you as effectively as 2 doses. You must get the second dose to complete the series for maximum protection.
