Why are you using the wrong number of doses? Do you really think the 333 million people living in the USA received 7 billion COVID-19 vaccine doses? That's 21 doses per person, including the children.
Is that some kind of common core math?
I misremembered total worldwide doses. It’s approaching 5 billion world wide. If there was rampant blindness we would have heard about it. I found one article on google about a guy who complained his eyesight got bad for a day or two after his second dose but then got better.
Blindness simply isn’t a common side effect. Stupid to suggest it is without a single documented case where blame is squarely on the vaccine. (And if there IS a case or two, do your own math to figure out the risk.) there are plenty of side effects, but blindness isn’t one.
