If it did leak from a Wuhan lab, which still seems like the Occam's Razor answer, where they were manipulating harmless bat viruses to make them super contagious - then do i want a lab manipulated vaccine (containing elements of the disease) to counter that lab engineered virus?

This is the $10,000 question.

The next point is: Old people have degraded immune systems.

And I would rate this as the $8,000 question, still very respectable.

I think a good vaccine is a godsend, but I don't think we should trust them blindly, like we do, say, postage stamps.

Before coming to Taiwan in late 1989 I started getting the first of three vaccine shots for hepatitis, what was it, B? It was the one that was endemic in Taiwan at the time. In fact, Taiwan had the highest rates of Hep B (?) in the world at the time, and it was basically fatal, usually leading to liver cancer. So, yeah, I got the vaccine, or at least the first shot, before leaving the US.

I went to a clinic in Kaohsiung after arriving to get the follow-ups, and the doctor confirmed that it was indeed endemic. What's more, she had herself tested before getting the vaccine, and found that she had acquired a natural immunity. So, due, apparently, to low dose exposure, she had acquired natural immunity to this deadly virus that was a top killer at the time, via liver cancer, in Taiwan.

So it is a very complex issue. Can taking a vaccine actually mess with an immune system that would otherwise fend off the disease? To what extent do we overgeneralize on the need for vaccination? When does it do more harm than good, and visa versa?
