This study could have been done two years ago…

Most of the victims had no idea they were affected and wouldn’t have gone to a doctor to get a blood test.

The new study shows the power of active surveillance for vaccine related injuries. The incidence of vaccine-induced myocardial injury (or heart damage) was estimated from hospitalization data to be 0.0035%. But a new trial which tested everyone who got an mRNA vaccine estimates it’s a thousand times higher or nearly 3%, and possibly much more common in young women than we thought.
In another surprise, most of the victims were women — fully 20 out of 22.
Up til now, we thought myocarditis was more common in young men, but perhaps that’s not the case? Women made up 70% of the healthcare workers in the trial but 90% of the victims.
