A recent study by the Global Vaccine Data Network analyzed 99 million individuals who received COVID vaccines from Pfizer, Moderna, and AstraZeneca, linking them to rare occurrences of heart, brain, and blood disorders. The study found a slight increase in neurological, blood, and heart-related medical conditions after vaccination.
Notable findings include cases of myocarditis with Pfizer-BioNTech’s and Moderna’s mRNA vaccines, and an increased risk of pericarditis with AstraZeneca’s viral-vector shot. Additionally, there were reported risks of blood clots in the brain and Guillain-Barre syndrome after receiving certain vaccines.
The New York Post adds, despite these findings, experts emphasize that the benefits of vaccination outweigh the risks, particularly when compared to the risks of contracting COVID-19. The study’s lead author highlighted the importance of large-scale studies in identifying rare safety signals associated with vaccines.
Overall, while rare associations were found between vaccines and certain medical conditions, the study underscores the importance of vaccination in reducing the risk of severe COVID-19 outcomes. Pfizer, BioNTech, Moderna, and AstraZeneca have emphasized the safety and efficacy of their vaccines in protecting against severe COVID-19 outcomes.
