The amount of youtube conspiracy theorists I've seen coming out of the woods since this whole pandemic started is out of this world.
I am very pro-vaccination. Nobody can describe vaccines better than Penn & Teller. If you haven't seen that video, look it up.
With that said, I'm not sure how I feel yet about the COVID-19 vaccine, mainly because it doesn't exist yet! Lots of possible ones going into trials, but there are tons of drugs that go through trials, fail, get reformulated, fail again, etc... The science just isn't there yet to make any sort of educated decision. So any youtuber stating any kind of theories or warnings regarding a vaccine is simply searching for views and is just adding to the problem.
