The U.S. Food and Drug Administration took more than a year to follow up on a potential increase in serious adverse events in elderly people who received Pfizer’s COVID-19 vaccine, according to an investigative report published Tuesday by The BMJ.
According to The BMJ, in July 2021, the FDA “quietly disclosed” the findings of a potential increase in four types of serious adverse events in elderly people who had received a Pfizer COVID-19 vaccine: acute myocardial infarction, disseminated intravascular coagulation, immune thrombocytopenia, and pulmonary embolism.
