This is a 2 years old belief that's convenient to politicians but has been utterly, comprehensively destroyed by science by now. It needs to die, yesterday.
For one thing, Covid-caused myocarditis is an order of magnitude or two more frequent than vaccine-caused myocarditis, at all ages. The latter also overwhelmingly resolves in a few days without treatment.
For another, there appears to be no such thing as durable "natural immunity" with Omicron. Reinfections are now documented to have happened as closely as 20 days apart !
Finally, not a single week goes by these days without a new study being released that describes "yet another creative way SARS-CoV-2 f*cks up the human body, yay!".
This week I suppose the most interesting development is a new meta-analysis reporting that HALF of people infected with Covid still have symptoms at least four months later (aka Long Covid) https://academic.oup.com/jid/advance-article/doi/10.1093/inf...
In the UK, an estimated 1.3 million people had long Covid as of early 2022, growing by 200K each month.
It was estimated that nearly a quarter million people had dropped out of the job market completely as a result :

Covid isn't going to immediately kill us all, but it's pretty obvious by now that it's already a mass disabling event, the main unknown being how reversible the neurological + cardio vascular damage is going to be in the long term.
