A study conducted by the US Food and Drug Administration (FDA) and various organisations, has detected safety signals – a set criteria that are indications of a vaccine causing an issue – for two specific concerns related to updated COVID vaccines:
- Myocarditis: A form of heart inflammation and related condition called pericarditis were observed following Pfizer vaccination in adults aged 18 to 35.
- Anaphylaxis: Severe allergic shock cases were reported following both Moderna and Pfizer vaccinations in people aged 18 to 64.
The study, which has not undergone peer review, analysed data from August 2022 to July 2023 for individuals aged 6 months and older. It focused on those who were continuously enrolled in an insurance plan and had not suffered health issues during specific intervals.
While the FDA maintains that these vaccines are “safe and effective” and that the benefits outweigh the risks, some experts have expressed concerns regarding cardiovascular and neurological safety events on a population level.
They argue that regulatory agencies should not promote products they regulate and that further research is needed.
