The most recent study on vaccines says that COVID-19 vaccines may be linked to very rare cases of brain, heart, and blood problems.
Researchers from the Global Vaccine Data Network looked at 99 million people who got the COVID-19 vaccine from Pfizer, Moderna, and AstraZeneca. It looked at 13 medical conditions and 8 countries to see if the vaccine stopped the spread of those conditions. In the end, the study did show that the shots did lead to more health problems with the heart, brain, and blood.
Myocarditis is a disease of the heart muscle that can last for a long time or a short time. It was found in people who got the first, second, and third doses of Pfizer-BioNTech and Moderna’s mRNA vaccines. It was found that people who got the third dose of AstraZeneca’s vaccine had more pericarditis, which is inflammation of the heart muscle.
Guillain-Barre syndrome is a neurological disease that was 2.5 times more likely to happen to people who got the AstraZeneca vaccine. Inflammation of the spinal cord was also found to be a possible risk, and there was a rise in inflammation of the brain and spinal cord, which is called acute disseminated encephalomyelitis.
More than 13.5 million people got a form of the COVID-19 vaccine, and some of them did have bad reactions or effects. This made the debate about the vaccine’s benefits very public.
As the lead author of the study put it, “The size of the population in this study increased the possibility of identifying rare potential vaccine safety signals.”
A medical professor who wasn’t involved in the study, Dr. Siegel, said this about the results: “It always comes down to a risk/benefit analysis of what you are more afraid of—the side effects of the vaccine or the virus itself, which can have long-term side effects like brain fog, fatigue, cough, and heart problems.”
