Major US study finds COVID-19 vaccines not linked to deaths

A study into vaccine side-effects, based in the US, has found no link between two COVID-19 jabs and the number of deaths recorded following vaccination. The US CDC reported that 92% of side-effects after the Pfizer and Moderna vaccines were mild.

Up to June 2021, roughly 4,500 people died after being vaccinated in the US. However, there were no unusual patterns detected in the data that showed a clear correlation to the vaccine itself.

Study author Dr Tom Shimabukuro commented: “[It’s] reassuring that reactions to both mRNA vaccines are generally mild and subside after one or two days – confirming reports from clinical trials and post-authorisation monitoring.”

Researchers of the study analysed “adverse events” from nearly 300 million vaccine doses administered in the US between December 2020 and June 2021. Any possible side-effects can be reported using the Vaccine Adverse Event Reporting System (VAERS), run by the CDC and the FDA. The results are published in the Lancet medical journal, and should serve as reassurance to Pfizer-BioNTech and Moderna vaccine recipients that the shots are safe.

Dr David Shay, from the CDC, said: “The rapid pace at which COVID-19 vaccines were administered under emergency use, especially among older populations, was unprecedented.”

“Due to their age, this group already has a higher baseline mortality rate than the general population and our results follow similar patterns of death rates for people in this age group following other adult vaccinations.”
