Once I am fully vaccinated, will I be able to pass on the virus to others?
This is still being studied, but preliminary data from the Pfizer, Moderna and Oxford-AstraZeneca vaccines looking at asymptomatic transmission of the virus (meaning have active virus that could be spread by having no symptoms) found that it was significant decreased in those who were vaccinated.
However, we do know that not everyone responds to these vaccines; and some vaccinated people still could get infected and not have symptoms. Those people can still spread the disease to others.
Bottom line: until we reach a point of “herd immunity” or get more data on this, you still need to wear a mask, social distance and wash your hands frequently to protect yourself and others.
