Could jab reaction be mind over matter?

I AM in my mid-80s, and – touch wood – am not on any medications. I couldn’t wait to get my first Covid jab, and then my second one. I never gave a thought that maybe I would get a reaction.... and never did...!!!

Nothing at all... But the next morning after each jab, I did wake up full of energy..! Could it be mind over matter?
