You have told us that re-infection with SARS-CoV-2 can cause a 10% incidence of cardiac problems, and things will worsen with each re-infection because of cumulative organ damage. Will the tissue injury be less during each bout of illness if people are vaccinated?

This is very much the case, that vaccination will reduce the severity for most individual recipients from any infection, the initial one or subsequent reinfection episodes. It is true that the vaccines themselves can cause tissue injury and this has been noted, especially for cardiac complications in young males, but that is a function of spike protein exposure. The illness itself causes much more intense exposure to spike protein than will be produced by the mRNA vaccine technology. Those who even react that noticeably with symptoms from vaccination would fare quite poorly with a frank bout of illness. So this is a trade-off that needs to be factored in, whether the incidence of illness and likelihood is so low in the young the risks of a vaccination outweigh potential benefits. But for those very susceptible to the illness, and particularly with recurring bouts of illness as a likelihood, given the transmissibility and perpetual circulation of such viruses once they get going in the population, providing a basic foundation of greater resistance to the injurious consequences through vaccination does make sense, all other things being equal. This can be quite serious. For some, it is a temporary problem, but for those less resilient there may be lasting damage and that can be an ongoing deficit into the future. The key is weighing the costs and benefits, as it will always be an individual decision. Granted, many times the potential vulnerability of the person affected will be a total unknown. So this is one of the unfortunate circumstances when society weighs in, wanting the greater good of the community, but it will be at the expense of subsets of individuals with differing benefit/risk ratios. That is the case here. The problem is lack of critical thinking by the medical community and absence of insight and wisdom on the part of the government officials setting the vaccine policy.
