Study led by FDA researchers didn’t find that the Pfizer-BioNTech COVID-19 vaccine caused blood clots, contrary to viral claims on social media

These findings suggest that the initially detected associations, obtained by comparisons with historical pre-COVID data, were the result of confounding factors—such as differences in healthcare-seeking behavior and monthly variations in the baseline rates of such adverse events—rather than true associations with the Pfizer vaccine. Confounding factors are variables that affect the outcome of an experiment, but aren’t the variables being studied in the experiment.
Yazan Abou-Ismail, a hematologist at the University of Utah Health who specializes in blood clotting disorders, also pointed out in a Twitter thread that the claim is inaccurate and the study “cannot be used to claim causality”.

  1. People are funny. They'll use cannabis which has a long list of side effects, some of them potentially serious, and they'll then turn around and say "Yeah, but I heard someone got a really sore arm for a week from the vaccine so I don't want it!"
