COVID-19 Vaccination and Cardiovascular Events: A Systematic Review and Bayesian Multivariate Meta-Analysis of Preventive Benefits and Risks Karimi, Raheleh1,2; Norozirad, Mina3; Esmaeili, Foad4; Mansourian, Marjan2,5; Marateb, Hamid R.6,7,8 International Journal of Preventive Medicine 16():14, March 2025. | DOI: 10.4103/ijpvm.ijpvm_260_24
This was a large meta-analysis reviewing 15 studies involving about 85 million people (45 million vaccinated, 40 million unvaccinated) from multiple countries across Asia, Europe, and North America. It was published in March 2025. Few controlled Moderna studies were available, so this study focused on the Pfizer (BNT162b2) and Astra Zeneca (ChAdOx1) shots.

COVID shots increased the risk of the following events/diseases:
Coronary Artery Disease (CAD)
Overall: 70% increased risk [OR 1.70 (95% CrI: 1.11-2.57)]
Pfizer: 64% increased risk [OR 1.64 (95% CrI: 1.06-2.55)]
2nd dose all vaccines: 244% increased risk [OR 3.44 (95% CrI: 1.99-5.98)]
Myocardial Infarction (MI)
2nd dose all vaccines: 286% increased risk [OR 3.86 (95% CrI: 2.28-6.60)]
Pfizer: 87% increased risk [OR 1.87 (95% CrI: 1.22-2.89)]
Pfizer 2nd dose: 284% increased risk [OR 3.84 (95% CrI: 2.21-6.66)]
Stroke
Pfizer: 109% increased risk [OR 2.09 (95% CrI: 1.36-3.21)]
Pfizer 1st dose: 269% increased risk [OR 3.69 (95% CRI: 2.13-6.37)]
All vaccines 1st dose: 240% increased risk [OR 3.40 (95% CrI: 1.98-5.86)}
Arrhythmia
All vaccines 1st dose: 199% increased risk {OR 2.99 (95% CrI: 1.20-7.44)]
AZ: 711% increased risk [OR 8.11 (95% CrI: 3.67-17.99)]
AZ 1st dose: 389% increased risk [OR 4.89 (95% CRI: 1.21-19.38)]
How can anyone look at this data and say the COVID shots are safe? They are not safe. They are dangerous and they are deadly…
A review study was done in 2023, analyzing all published autopsies related to COVID-19 vaccination. In total 44 papers representing 325 autopsy cases were studied.
The most implicated organ system was the cardiovascular system (49%).
Most deaths occurred within a week from last shot administration.
240 deaths (73.9%) were independently adjudicated as directly due to or significantly contributed to by the COVID shots.
The primary causes of death included: cardiac (35%), pulmonary embolism (12.5%), myocardial infarction (12%), VITT (7.9%), myocarditis (7.1%), multisystem inflammatory syndrome (4.6%), and cerebral hemorrhage (3.8%).
VAERS is the vaccine adverse event reporting system managed by the CDC and FDA. It is a voluntary reporting system, thus its numbers grossly underestimate the true number. Case reports are carefully vetted by the CDC before they are added to the database. Submitting a false report is against federal law, a felony, and punishable by fine and imprisonment. As you can see the total number of reports of death associated with vaccination was quite low for many years – until 2021. No previous vaccine has ever been associated with nearly as many deaths as the COVID shots. Indeed, the COVID shots have resulted in more reports of death than all other vaccines combined.
