A massive study of 85 million people has raised alarms about COVID-19 vaccines, suggesting a link to increased risks of heart attacks, strokes, and other serious heart issues. The findings challenge the narrative around vaccine safety and call for deeper scrutiny.
Uncovering the Risks
Published in the International Journal of Preventive Medicine, the peer-reviewed study analyzed data from 85 million individuals across multiple countries. Titled “COVID-19 Vaccination and Cardiovascular Events,” it used advanced statistical methods to explore how vaccines like Pfizer, Moderna, and AstraZeneca affect heart health. The results, reported by IndependentSentinel.com, show a troubling rise in cardiovascular risks post-vaccination.

Key Findings
The study, led by biostatistician Rheleh Karimi from Iran, found significant increases in several heart-related conditions after vaccination, particularly with mRNA vaccines like Pfizer and viral vector vaccines like AstraZeneca:
- Coronary Artery Disease: Up to 244% increased risk after the second dose.
- Heart Attacks: 286% higher risk after the second dose of any vaccine, with Pfizer showing a 284% spike.
- Stroke: 240% increased risk after the first dose, with Pfizer at 269% for its first dose.
- Arrhythmia: 199% higher risk after the first dose, with AstraZeneca linked to a 711% surge.
These numbers suggest that even a single dose could elevate risks of stroke, coronary artery disease, and arrhythmia, raising questions about long-term impacts.
What Does It Mean?
While the study doesn’t prove the vaccines directly cause these issues, the patterns are concerning. The researchers noted that mRNA vaccines (Pfizer, Moderna) and viral vector vaccines (AstraZeneca) showed varying risk levels, with second doses often amplifying the effect. This has sparked debate about whether the push for widespread vaccination overlooked potential vaccine safety concerns.

Global Implications
The findings come at a time when trust in public health measures is shaky. With vaccines like Pfizer and AstraZeneca linked to such stark risk increases, individuals with heart conditions or other vulnerabilities may need to weigh their options carefully. The study urges more research to clarify these risks and guide future health policies.

Looking Ahead
This research doesn’t negate the role vaccines played in curbing COVID-19’s spread, but it highlights the need for transparency. As the world moves forward, balancing benefits against risks will be key. For now, these findings are a call to listen to the data and prioritize heart health in the vaccine conversation.
