General, the research found a more powerful association concerning the Moderna vaccine and myocarditis or myopericarditis, although the Pfizer vaccine was linked only to an greater price of the two circumstances amid ladies.

Though the price of myocarditis or myopericarditis was greater just after Moderna vaccination than just after Pfizer vaccination, the absolute amount of heart activities just after both vaccine was low, and most circumstances ended up mild, in accordance to the report posted Dec. 16 in the BMJ.
