I'm summarizing him and everyone else with attitudes like his: the vaccine isn't 100% so it is nothing. Maybe I'm a bit extreme, but at this point I am tired seeing the same ensconce.
My own estimate is that the vaccine is about 50% effective for delta. That's cuts R0 in half, which is huge, but not something you can in any way, shape, or form rely on in isolation. It will likely be even lower for future mutations. Aside from the antivaxer movement, another outcome of extreme pro-vaccine stances, to the level of people lying, is that many people take NO precautions once vaccinated. That's a lot of what's driving some (not all) of the current delta outbreaks.
And on the anti-vaxxer side, once scientists get caught fabricating data, they're not going to be trusted even when they're right.
Your summary of their position is so bad I've flagged your comment: "if it isn't 100% perfect you have decided it is worthless."
