To me SEVERE means DEADLY. ANAPHYLAXIS maybe which can be deadly.
I know. My son suffers from ANAPHYLAXIS and ALWAYS carries an Epi pen with him wherever he goes.
I don't know if the SEVERE reactions were due to anaphylaxis. I do know that SEVERE is not good in even 1.
100 mild reactions is ok. Mild doesn't do permanent harm. 25 Medium reactions? I dunno. Marginally iffy.
BUT EVEN ONE SEVERE REACTION is terrible and there were SIX! I wouldn't want to get the Moderna vaccine. Would you?
