Dr Vinay Prasad, a professor from Stanford weighs in on this https://www.drvinayprasad.com/p/it-is-disappointing-that-the-cdchttps://www.drvinayprasad.com/p/it-is-disappointing-that-the-cdc
"It is disappointing that the CDC is dishonest
A new study exonerating mRNA vaccines in young men is inconclusive; the CDC is shredding its own credibility"
Here's a couple points he raises
"At one point in the paper, the authors actually admit the truth, the “small population size made it less likely that Oregon would see a rare event such as sudden cardiac death among adolescents and young adults.”
"With these facts, almost surely, the vaccine does increase death from cardiac reasons (as some people get myocarditis and some of these people will die), though this signal will be small, and too small to see in a single, low population state (Oregon)"
