You understand that none of this is an argument against vaccines, right?
I mean, let's consider an outcome where the whole world gets vaccinated. There would likely be a handful of deaths from cavernous sinus thrombosis or DVT or anaphylaxis. Maybe. AND THEN ALMOST NO ONE ON THE PLANET DIES FROM COVID-19 (you know, in EXACTLY the same way that we don't die from polio and we don't die from smallpox). Furthermore, even if a vaccinated person passes the delta variant to another vaccinated person (which is unlikely), no one dies from that either.
Contrast that to a world where no one gets vaccinated, and we continue to suffer socially and economically with years and years of masks and distancing and "hey, kids, don't go near Grandma!" Sporting events and religious ceremonies are life-threatening endeavors. Educating an entire generation is problematic to say the least. Healthcare workers leave the field in droves (which is already happening). And we'll have TENS OF MILLIONS OF MORE DEATHS. But hey, everyone, look at the bright side! THOSE OF US WHO SURVIVE OUR COVID INFECTIONS AND HAVE ANTIBODIES MIGHT BE LESS LIKELY TO GET THE DELTA VARIANT! AS IF THAT WOULD BE A MEANINGFUL FUCKING METRIC. And it also ignores the fact that in an unvaccinated world, there is going to be a lot more delta variant and every other variant bouncing around for generations to come.
Your post is an excellent example of how anti-vaxxers will always find conspiracies, half-truths, and fallacious arguments, and they'll repeat all of them to anyone who will listen... despite overwhelming evidence that they're wrong.
Apologies to the board for engaging the obvious troll, but there might be a few people out there on the fence of whether to take the vaccine, and I wouldn't want those people to mistake GRHorn's nonsense for a meaningful argument.
Thank God we got smallpox off the table a few decades before the trolls got broadband. We'll never do anything like that again.
