Before my first Pfizer shot my platelets were 147. A week after the first shot they were 110, then another week later they were 112.
Had my platelets tested yesterday (1 week after the 2nd Pfizer) and they were 129. So I am pretty happy it is over with. I have reactions to 'normal' vaccines and I have to say I had a lot LESS reactions to the mRNA vaccine. I did have mouth bleeding on the 3rd day after the 2nd shot, but it is gone now and my platelet count 7 days after the 2nd shot was 129 as I said, so I don't know if that was possibly a transitory crash.
