How many people experience adverse events from the flu vaccine?
Between 2012 and 2022, 300 deaths were reported as a result of flu shots, according to the Vaccine Adverse Event Reporting System (VAERS) on the CDC website. However, because not all healthcare practitioners record vaccination-related adverse events to VAERS, it's likely that the flu vaccine contributed to more deaths during this time period. Some healthcare practitioners are unfamiliar with the process of completing a VAERS report or are unaware of when they are obligated to file a VAERS report, according to a 2013 study published in Vaccine.
