Let me stop you're right there. This isn't true. The rest of your argument follows from this faulty premise.
> There were 1,626 cases of myocarditis among more than 354 million primary doses given between December 2020 and August 2021. This research was published in the journal JAMA on January 25, 2022. [1]
That is objectively and subjectively not "a lot." That's 1626 out of 354,000,000. 0.00045%. 0.45/100,000.
> There were 37 cases of myocarditis among more than 81 million booster doses given between September 22, 2021, and February 6, 2022. This research was published by the CDC on February 11, 2022. [2]
That is objectively and subjectively not "a lot." That's 37 out of 81,000,000. 0.000045%. 0.045/100,000.
The reality is with 5.56B people vaccinated, if it had any effects, it would be clearly and plainly visible in population-level data.
You are wrong, the monitoring is extensive, the vaccine is safe, and this is settled science.
ergo, MSG.
