Nothing in your link supports the claim "we know the vaccine improves survival regardless of previous infections."
> It doesn't matter in countries like the US where the vaccine is free to anyone who wants it
How about the medical bills for a life-altering adverse event? Are those free for anyone who has to pay them? These considerations matter when we're talking about administering a vaccine which may provide very slim or no additional protection over natural immunity. There has already been one study suggesting the second dose of Pfizer even reduces cellular and humoral immune response.
What that study shows is that unvaccinated people in the study cohort were twice as likely to experience a reinfection. A lot of things could explain that and it's a far cry from establishing that it boosts immunity. The study period was also during the point when effectiveness of the initial mRNA vaccine doses was probably peaking.

Like when you get seriously ill with Covid and have to be hospitalized in the ICU? That's more likely than an adverse reaction to a vaccine, if we're assuming that everyone will get Covid at some point.
We're specifically discussing people with immunity from having recovered from a prior Covid infection, in whom serious life-altering illness from a reinfection is also extraordinarily rare.

Only as far as we're talking about reinfections from currently known variants. We've seen that current vaccines are still pretty good against Delta despite not being tailored to it. Is it not possible for vaccines to provide immunity against a future variant that's much deadlier upon reinfection?
