People already have immunity usually react to the first shot because your body can recognize the virus without any "training". For people who don't have any immunity, the first shot is the "training" which make your body remember this virus, then react to it when exposed to it again the second time/shot.
My daughter had the J&J vaccine today.....she is normally a big baby with these things and imagines all sorts of things lol however I kept her busy with a nice lunch and a look around the shops......it did the trick no after effects so far and no pain in her arm.....I had zero effects and no arm pain from Pfizer,I to kept busy that day and did not acknowledge my arm....for me I feel thoughts are powerful .....if she is ok tomorrow I will be convinced it's mind over matter ...fingers crossed 😂
I know what you are saying ....I dont trust the whole climate of things and certainly not Bill Gates...life has gone beyond wanting honesty and goodness for all...it's all greed and money,so nothing surprises me. However I am at the stage of having to ignore it all,I will worry myself to death,
