We will find out many things, but we cannot be sure it has wiped out covid at all. We had very few new cases last summer without a vaccine and it came roaring back in the fall/winter. What we are seeing now may just be “seasonal” like last summer. Nobody knows how long these vaccines may be effective - I suspect all the talk about booster shots and the fact that they require 2-shots spaced 4 weeks apart suggest that they know that the efficacy, if any, is short lived. It does seem that they prevent, in most cases, serious illness resulting from infection and that is a good thing. If they don’t stop the spread of disease, helping people from serious illness is good and it will spread a natural immunity among those who do catch it. But I wonder if the vaccines aren’t just buying time on a hope and prayer that the virus won’t mutate further, or will actually encourage more dangerous strains to “escape”.
I’ve had hundreds of covid visits in hospital both on covid floor and covid icu. I recommend vaccination but wouldn’t require. Not a bit worried about the longterm risk of the shot.
I seriously doubt any of the theories but I guess we will see.
