I didn't see your videos. It was a terribly painful jab, either time, but they definitely stuck me and pump something in. I could not possibly count the number of times the government has stuck me in the arm or pressure injected into my skin. Vaccines are not something I have much reaction to, except maybe the black plague shot I had before an overseas assignment. It did not last more than a day. I do recommend you don't get the plague shot and then fly for 12 hours the same day.
No. I do not know what was in the shot, even though I can tell you the Moderna batch and lot numbers. My only reactions were being tired and running a 99.5 fever part of the next day, and then the reaction was over. I had it March 12 and April 10. I can tell you I haven't had Covid-19 since then. I would know it, as I had it last year, and it truly sucked.
