Took me a minute to figure out you're talking about myocarditis. Yeah, that's a common one. In olden days, they'd pull a vax off the market after a hundred or so cases of adverse results.
This time, they just pushed the propaganda and ignored the side effects and bulldozed ahead with it. My conclusion is that they have been trying to kill people.
Now they're pushing a shot for RSV, which was always one of those things babies pass around in daycare, and then have natural immunity after. If you look at it in the electron microscope, RSV is a scary looking virus, but so far it hasn't created a race of lizard people..
