The paper also notes a vaccine failure amount of 16 out of millions of doses. Crunching the numbers, that's a success rate of 99.999985%. If this is the slam dunk that anti-vaxxers use to prove how bad the Pfizer vaccine is (like that guy claimed, as he said that was the answer for Pfizer trending on Twitter), then their argument sucks.

Let's take U. S. vaccination data, meaning around 214.2 million people got 2 vaccine doses (65%*population of US) .

If we very generously assume the ratio for vaccination it was 50-25-25 for Pfizer, Johnson and Johnson, and Moderna (it is likely that Pfizer has a higher ration, but whatever) then that's 107.1 million total cases. If 16 of these cases failed, that is a success rate of 1-(16/107.1 mil), or a 99.999985% success rate.
