PHILADELPHIA (KYW Newsradio) — Why is testing for COVID-19 necessary after a person has been immunized against the virus?
The key point is that vaccines do not make you immune to the virus. Certainly, vaccines dramatically reduce symptoms as well as the amount of time you are infectious.
However, testing is very important if you feel you have symptoms. One reason is if you need treatment, it can be initiated earlier.
Another key reason is to make certain that you reduce the chances of spreading the virus to someone else — you can begin to isolate to protect others.
This knowledge also helps researchers gain a better understanding of viral spread in the community.
