Recently, a post by Heidi Neckelmann, the wife of Miami obstetrician Dr. Gregory Michael describing his death from idiopathic thrombocytopenic purpura (ITP) 16 days after being vaccinated with the Pfizer/BioNTech COVID-19 vaccine went viral. Unsurprisingly, in her grief she blamed the vaccine for her husband’s death from a rare autoimmune condition that destroys platelets and causes bleeding. Unfortunately, Dr. Michael’s tragic death underlines the difficulty distinguishing coincidence from causation when evaluating adverse events after vaccination.
