According to Dr. Meryl Nass, there are several flaws to ACIP’s presentation. She says, “As of now, two major ways the rate of myocarditis were minimized [during the presentation] was to lump people from age 39 and down — even though the highest rates [of myocarditis] are in the youngest kids. This waters down the rate. The other method was to only include a very narrow window of time after vaccinations started in the 12-15 age group, thus omitting the vast majority of second doses, which is when about 75% or more of the myocarditis cases occur.
