A recent Pfizer report on Covid vaccine safety, which has not been made public, suggests that vaccinated individuals may face a higher risk of heart-related conditions. This information comes from an abstract of the report on Comirnaty that has surfaced online.
Key Findings from the Report
The report, known as “Interim Report 5,” dated March 12th, 2024, is part of a Post Authorisation Safety Study (PASS) of Pfizer’s Covid vaccine Comirnaty. Some concerning findings include:
- Vaccinated individuals show a 23-40% higher risk of certain heart-related conditions
- The risk appears to be increasing over time since vaccination
Understanding PASS Studies
PASS studies are routinely required by health regulators to monitor the safety of new medicines after they’ve been approved. These studies analyze data from millions of patients to determine if a medicine increases the risk of specific health issues.
Difficulties in Accessing the Full Report
Despite previous reports being made available through Freedom of Information requests, the UK’s Medicines and Healthcare products Regulatory Agency (MHRA) has been reluctant to release this latest report. They initially stated it would be published in late 2024 but later backtracked on this commitment.
Analyzing the Available Data
The abstract reveals increased risks for several heart-related conditions in vaccinated individuals:
- Myocardial infarction: 23% higher risk
- Pericarditis: 36% higher risk
- Myocarditis: 39% higher risk
- Coronary artery disease: 24% higher risk
- Arrhythmia: 23% higher risk
- Heart failure: 28% higher risk
These figures represent average risks across all age groups. The full report likely contains more detailed breakdowns by age, which could be crucial for understanding the risks for younger individuals.
Potential Explanations and Limitations
The report acknowledges potential factors that could influence these results:
- The severity of conditions may vary between vaccinated and unvaccinated groups
- Vaccinated individuals might be more likely to seek medical attention, potentially skewing the data
However, without access to the full report, it’s difficult to fully evaluate these explanations.
Implications and Next Steps
The findings raise questions about the long-term safety of Covid vaccines, particularly for younger people who were at lower risk from Covid itself. As the UK’s Covid Inquiry prepares to examine vaccine-related issues in early 2025, there are calls for this report to be made available to ensure a thorough investigation.
Conclusion
While these findings are concerning, it’s important to note that this information comes from an unpublished abstract. Full transparency from health authorities and vaccine manufacturers is crucial to maintain public trust and make informed decisions about public health policies.
