A member asked:
At what point do you have good protection from a pfizer booster? ive seen both one week and two weeks. what does the data say?
A doctor has provided 1 answer
"One to two weeks" is exactly right. There probably is partial protection beginning around 7-10 days with maximum protection being achieved at around 2 weeks. Probably faster after the second or third than the first dose.
