I do know that because the published research results demonstrate it, and simply looking at the people who’ve been vaccinated early on demonstrates it. Heck, I got my first shot back in January. Why am I still alive? Why am I not growing unicorn horns or wings? Why won’t my Bill Gates microchips connect to the 5G towers so the lizard people can control my brain?
The sheer amount of nonsensical fearmongering that conflicts with observable reality being spread about these vaccines is stunning. Thank God this garbage wasn’t around when smallpox and polio were being wiped off the face of the globe or else kids today will still be facing them. This new-age antivaxxer stuff used to be strictly among the far left mommies groups that believed that anything that didn’t grow on a tree was going to kill you. Somehow, they infected the conspiracy nuts on the right some time after Jenny McCarthy’s “vAcCiNeS cAuSe aUtIsM” tirades faded away (after massive amounts of research demonstrated that no, they don’t actually cause autism and you can detect the presence of autism before the MMR shots are even given).
Logic, reason, and evidence still matter. Facts still matter. There is one objective reality that’s real and we all exist in it, even when some choose to ignore it in favor of some alternate reality (i.e. fantasy).
You do understand there are long term effects not known which is why vaccines are tested at least 5 years before releasing? The other effects may not show immediately , our thinking on everything is short term, not long term. When the other effects show up they may or may not be a disaster, we don’t know.
