You Make Me Itch

OK, so Rogers is claiming he's 'allergic' to something in the mRNA vaccines. What might that be? Turns out, the only known allergen is polyethylene glycol, aka PEG. Turns out the frequency of reactions is smaller than an RCH.

There have been approximately 5 cases of a severe allergic reaction to these vaccines per 1 million doses administered.
...
A review of the scientific literature reported 37 cases of an allergic reaction to PEG from 1977 to 2016. However, only 28 of these cases actually met the criteria for a severe allergic reaction (i.e. anaphylaxis).

And, no, there is no test for PEG allergy. In other words, Rogers is full of shit.

There is no commercially available blood test for PEG allergy at this time.
