Wife and I took the derna shot after watching a lot of our friends, family, and my customers die horrible deaths from covid. I have had joint pain ever since and I am convinced it was from that damn shot. Not 1 but 2 of my friends got the pfizer shots. Within a few weeks both had to have stents put in their hearts and had to take blood thinners. Another friend of mine got a booster, not sure how many, but knowing him he probably has taken every one available. A few months ago he has a stroke while he was working out. I say that schnit aint no good and nobody is going to change my mind about it.
