This study used data from CDC, FDA, and VAERS databases from 1990 through 2023. It compared reports of Adverse Events after COVID shots compared to those after influenza vaccines and to all other vaccines. It did this by using Proportional Reporting Ratio (PRR). PRRs are a statistical measure to help detect whether a specific adverse event from one drug is reported more often compared to another. It is commonly used to identify potential safety signals. A PRR of 1 means the Adverse Event was reported at the same rate for both drugs. A PRR of 2 means the Adverse Event was reported twice as often in the subject drug compared to the comparison drug. Indeed, a PRR of 2 is the usual cut off to trigger a safety signal.
Cerebral Venous Thrombosis was reported 2000 times more often after COVID shots compared to influenza vaccinations (PRR 2070: 95% CI, 955-4490, p < 0.0001).
Cerebral Arterial Thrombosis was reported 1000 times more often after COVID shots compared to influenza vaccinations (PRR 1120: 95% CI, 152-8280, p < 0.0001).
Total Cerebral Thrombosis was reported 1000 times more often after COVID shots compared to influenza vaccinations (PRR 1120: 95% CI, 723-1730, p < 0.0001).
Atrial fibrillation was reported 100 times more often after COVID shots compared to all other vaccines (PRR 123: (95% CI, 88.3-172, p << 0.0001).
Further, the “Pfizer post-marketing analysis done from December 10, 2020 to February 28, 2021 [documented] 42,086 casualties including 1223 deaths in just the first 10 weeks of rollout.”*
*BNT162b2 5.3.6 CUMULATIVE ANALYSIS OF POST-AUTHORIZATION ADVERSE EVENT REPORTS OF PF-07302048 (BNT162B2) RECEIVED THROUGH 28-FEB-2021. Report prepared by Worldwide Safety Pfizer for the Federal Drug Administration and approved on April 30, 2021.https://phmpt.org/wp- content/uploads/2021/11/5.3.6-postmarketing-experience.pdf. (Accessed June 15, 2023).
By the way, this 10 week analysis is part of the Pfizer data that the FDA requested to stay sealed for 75 years. Well, they lost that lawsuit and in January 2022 a federal judge ruled that the FDA must expedite the release of these documents.
Apparent risks of postural orthostatic tachycardia syndrome diagnoses after COVID-19 vaccination and SARS-Cov-2 Infection Alan C. Kwan 1 , Joseph E. Ebinger 1, Janet Wei1, Catherine N.

This study was done in Los Angeles and Boston in 2022 and involved 284,592 vaccinated patients. Patients received Pfizer (62%), Moderna (31%), or Johnson & Johnson (6.9%) [less than 0.1% received another product such has AstraZeneca or Novavax]. They compared medical diagnoses that occurred within 90 days after vaccination compared to the 90 days before vaccination. The three diagnoses that had the highest post-vaccination odds were myocarditis, dysautonomia, and POTS.
Myocarditis risk increased by 157% [OR 2.57 (95% CI: 1.02-6.77, p = 0.046)].
Dysautonomia risk increased by 124% [OR 2.24 (95% CI: 1.30-3.87, p = 0.002)].
POTS risk increased by 52% [OR 1.52 (95% CI: 1.36-1.71, p < 0.001)].
Note the gender differences. Myocarditis was more common in males. POTS was more common in females.
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 2nd dose: 284% increased risk [OR 3.84 (95% CrI: 2.21-6.66)]

Arrhythmia
All vaccines 1st dose: 199% increased risk {OR 2.99 (95% CrI: 1.20-7.44)]

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…
