I recently had my Pfizer booster and had a delayed reaction a week later of fatigue. Since I am recovering from adrenal fatigue it was hard for me to say it was from the booster but after thinking about it my adrenals have been doing much better so I think it is due to the booster.

And the itching you mentioned, I’ve been having that before my booster and was attributing it to drinking too much green tea as some people can be sensitive. Now you have me wondering.
