It's far too early to be sure though.
Its not some different product, its the same vaccine.
For young males, the risk of myocarditis from the vaccine may be comparable to that from the disease according to a UK study - until that’s clarified, booster mandates have no place in colleges.
Sudden cardiac arrest incidents increased in 2020 (vaccine was not officially realeased until Dec. 2020).[2]
I added the second link to show there may be a rise of cardiovascular disease not due to the vaccine. I'm interested in seeing data for 2021.

monetary costs are not the only costs you pay
Why would I sicken myself for a few days with the next vaccine shot to marginally decrease the odds I will be sick for a few days from covid?
