A member asked:
After fully vaccinated for covid, how long do body need to fight infection after an exposure to virus or after it enters your body ? what do we know from other vaccines as well?
A doctor has provided 1 answer
Immediately after the covid 19 vaccination, a healthy person's body begins to recognize and produce antibodies and specialized cells that are specific to the protein found coded for in the vaccine. They continue to be made in increasing numbers over the 21-28 days until the second vaccine is given. At that time, the body more readily recognizes the protein and mounts a more vigorous response.
