I can't find any data where the above is true (& why use quotation marks for "vaccinated" unless you believe they were dosed with a fake vaccine?).

According to the NY Times, the CDC acknowledges that in some areas, as the percentage of vaccinated people increases, breakthrough infections among them might also increase. But severe morbidity & mortality among Covid patients appear to confined to the unvaccinated in any area I can find.

Futher down you imply that myocarditis is synonymous with "enlarged heart" (i.e. cardiomegaly). Not true. Cardiomegaly is a symptom associated mainly with pericardial effusion, pulmonary hypertension, CHF & several other conditions. Not myocarditis (infammation of the heart's lining) as far as I can tell.

There are risks, of course, with Covid vaccines. I think the CDC has been fairly upfront about them. The J&J vaccine, for example, was put on hold briefly after reports of blood-clotting emerged among some recipients. And, of course, people should be informed of both short & long-term risk-benefits.

But, like many vaccine-skeptics, you appear not to take into account some of the long-term effects of severe Covid infection, including congestive heart failure, Guillian-Barre, chronic fatigue, chronic dyspnea, loss of taste, cognitive disabilities, etc.

mRNA vaccine technology isn't new. It's been around for decades now.

Your article makes several fair points, but one cannot intelligently make a benefit/risk analysis of being vaccinated without weighing it against the risks of contracting the disease itself.
