FDA Study: Pfizer Vaccine increases risk of Blood Clots in the lungs by 54% in Over 65's

The FDA recently published a study which looked at the COVID-19 vaccine safety among elderly persons aged 65 years and older. Today it was published in the Vaccine Journal.

The study looked at 30,712,101 individuals who had received various doses of the Pfizer, Moderna and Johnson & Johnson vaccines between 11 December 2020 and 15 January 2022.

Worryingly they identified four statistical signals for elevated risk of acute myocardial infarction (ACI), pulmonary embolism (PE), disseminated intravascular coagulation (DIC) and immune thrombocytopenia following the Pfizer vaccine. They didn’t find any statistical signals for the Moderna or Johnson & Johnson vaccines for the 14 outcomes they were monitoring.

PEs (blood clots on the lungs) were 54% more likely, ACIs (heart attacks) were 42% more likely, DICs (blood clotting disorder) were 91% more likely and ITPs (platelet disorder) 44% more likely.

However, they say that after further evaluation the rate ratios for AMI, DIC and ITP no longer met the statistical threshold for a signal. But, even after their further evaluation, the rate ratio for PE still met the statistical threshold.
