Explaining the distortions in a widely circulated article which alleges many kinds of sloppiness in a 2020 clinical trial of the Pfizer vaccine, and exaggerates their significance.

If the facts in the article are accurate, most of them have no effect on the validity of the trial's conclusions. As explained here, they had a small chance of affecting some 1000 -- out of 44000 total subjects -- in the trial.

That 2020 trial is irrelevent for evaluating the Pfizer vaccine nowadays, because we now have records of hundreds of millions of people who have been vaccinated with it. That is far more evidence than the trial gathered, and shows conclusively that the vaccine does considerable good and hardly any harm.
