I just read something which was genuinely news to me

I did not know at all the difference between boosters (given routinely 6 months after 2nd dose) and 3rd doses given to immune compromised people which is given much sooner, and that many immune compromised people should be onto their 4th dose by now.

I’m shocked that many professionals delivering the vaccines didn’t know this either.
