I received my pfizer covid booster yesterday. immediately after the shot, i felt sleepy. today, over 24 hours later i developed a low grade fever. is that normal to develop a fever more than 24 hours afterwards? i took 2 tylenol for the fever?

That definitely can be a response to the booster as your antibodies react. Such reactions do occur within a week after vaccination. Taking Tylenol is a proper move.

Nothing unusual about your sequence, as almost certainly a mild reaction to your vaccination.
