The mRNA in Moderna’s vaccine is three times heavier than the mRNA in Pfizer’s vaccine! Furthermore the mRNA sequence between the two is also different.
Either there’s a right amount or a wrong amount of mRNA and a right sequence or a wrong sequence of mRNA.
The fact that Moderna and Pfizer are using different vaccines but claim to make the same spike protein tells you one, if not both, are playing with your health.
Furthermore, there is nothing speculative about asking why the vaccine causes myocarditis.
It’s called “Do no harm.”
Genuine medical professionals would never speculate as to the side effect of a medical treatment.
