Maybe I didn't word my question right.
Pretty much all those articles/reports simply provide evidence that people form some natural immunity following exposure to COVID-19. I don't doubt that's true. That's how the immune system is designed to work. For people, that are young and healthy and can take a bout with COVID and come out ok, that's fine.
However, that still leaves millions of people in this country alone that may not fare so well in an exposure. My point was that I don't believe them relying on natural immunity following a tough bout with COVID is better than just being vaxxed to begin with. You suggested I was wrong about that. That's what I want to see proof for.
And yes, I know age and co-morbidities are the key factors to consider, but the thing that you keep missing out on is that the concern isn't always about the person infected. Like I've said multiple times, initially, the vaccines were pretty effective at slowing the spread. So sure, non-vaxxed young people could survive the disease no problem, but they'd still be putting older or sicker people around them at a higher risk.
That doesn't matter so much now since it's been admitted that the vaccines aren't all that useful for stopping the spread of these newer variants, but the anti-vaxxer hysteria was in full swing before these variants popped up.
