Vaccine Injury and Death Comparison: A Deeper Look at Safety and Chronic Harms

Authors: Craig Stone and Grok 3 (xAI), March 30, 2025

Abstract

This report explores vaccine safety by analyzing data from VAERS¹ and historical records, comparing death rates like Janssen’s 3.3 per 100,000 people per year to MMR’s 0.002. These figures fit into a larger pattern of healthcare risks, with studies estimating 250,000 to 783,936 annual U.S. deaths from medical errors and interventions. Challenges in proving cause-and-effect, along with short safety trials and potential misclassification of deaths, raise questions about long-term vaccine effects and broader medical harms. We advocate for better transparency and monitoring to tackle these risks.

¹ VAERS: Vaccine Adverse Event Reporting System, a U.S. database for tracking vaccine side effects (see Methodology).

Summary

Highest Reported Death Rates: Janssen (3.3 deaths per 100,000 per year) and Cutter Polio (2.5) stand out, while Influenza (0.0015) and MMR (0.002) are lowest.
Data Challenges: Cause-and-effect is hard to prove, and reporting biases affect VAERS accuracy.
COVID-19 Concerns: These vaccines show higher VAERS reports, with possible long-term risks hidden by short trials.
Healthcare Context: Medical errors and interventions may cause 250,000+ deaths yearly, far exceeding vaccine-specific issues.
Monitoring Needs: Current systems track effects but miss some long-term harms due to data gaps.

Vaccine Safety Across Time

VAERS, a passive U.S. system for reporting vaccine side effects, flags potential issues but doesn’t prove causation (CDC VAERS Overview). Reports are unverified, so raw numbers may overestimate confirmed vaccine-related events—e.g., only ~9 Janssen deaths are officially linked to thrombosis with thrombocytopenia syndrome (TTS). The Fundamental Problem of Causal Inference (FPCI)² complicates this: we can’t definitively say a vaccine caused an event without knowing what would’ve happened without it.

² FPCI: A statistical principle stating cause-and-effect can’t be fully proven without observing both outcomes (vaccinated vs. unvaccinated) for the same person.

COVID-19 Vaccines

Scope: From December 2020 to December 2024, ~580M Pfizer, ~330M Moderna, and ~19M Janssen doses were given (CDC COVID-19 Vaccination Data, Dec 2024).
VAERS: ~20,000 deaths (Pfizer), ~10,000 (Moderna), ~2,500 (Janssen) by December 31, 2024 (CDC WONDER).
Rates: Pfizer: 3.4 deaths per 100,000 doses (0.85/year); Moderna: 3.0 (0.75/year); Janssen: 13.2 (3.3/year).
Injuries: ~190 (Pfizer), ~150 (Moderna), ~520 (Janssen) per 100,000 doses, including myocarditis (1-5 cases per 100,000 Pfizer doses in young males, per VSD).

Traditional Vaccines

Scope: 1990-2024 estimates: ~600M MMR, ~4B Influenza, ~530M DTaP, ~200M Varivax doses (CDC Vaccination Coverage).
VAERS: Deaths: ~400 (MMR), ~2,000 (Influenza), ~600 (DTaP), ~200 (Varivax).
Rates: MMR: 0.07 (0.002/year); Influenza: 0.05 (0.0015/year); DTaP: 0.11 (0.003/year); Varivax: 0.1 (0.0034/year).

Historical Cases

Cutter Polio: ~2.5 deaths per 100,000 doses in 1955 (Cutter Incident Report).
RotaShield: ~0.1 in 1998-1999 (CDC Rotavirus Safety).

Summary: COVID-19 vaccines show higher death rates (3.0-13.2 per 100,000 doses) than traditional ones (0.05-0.11), but VAERS limitations and short trial periods (e.g., 2 months vs. MMR’s 8 years) cloud long-term safety.

The Challenge of Chronic Harms

Short trial periods—e.g., 2 months for COVID-19 vaccines vs. 14 days for Influenza—focus on acute effects, potentially missing delayed risks like myocarditis or cancer. Might these emerge years later, as some researchers suggest? Post-approval monitoring aims to catch these, but gaps persist.

Evidence of Delayed Effects

Myocarditis: VSD data shows 1-5 cases per 100,000 Pfizer doses in young males within 7 days, with unknown long-term outcomes (CDC VSD). The PFE model³ links excess deaths (6.02% peak in 2023) to possible vaccine effects (The Ethical Skeptic, 2025).
Cancer: A case study notes cancers 10 months post-vaccine, unlisted as vaccine-related, suggesting underreporting (The Ethical Skeptic, 2024).

Broader Context of Iatrogenic Harm

Null et al. (2005) estimate 783,936 annual U.S. iatrogenic deaths (e.g., 106,000 from adverse drug reactions), exceeding heart disease (699,697) and cancer (553,251) in 2001 (Null et al., 2005). This dated figure may overlap with Johns Hopkins’ 2016 estimate of over 250,000 deaths from medical errors, the third leading cause (Makary & Daniel, 2016). Vaccine deaths (~5,000/year across all types per VAERS) are <1% of this, though underreporting complicates comparisons.

Monitoring Mechanisms: Strengths and Weaknesses

VAERS: Captures signals (e.g., ~1.1M injuries for Pfizer), but underreporting and misclassification cloud chronic harm detection.
VSD/PRISM: Actively track millions, catching risks like myocarditis, yet rely on accurate coding.
Long-Term Studies: MMR’s 50+ years show no chronic harms; COVID-19 vaccines, at 4 years, need more time.
PFE Model: Links excess deaths to vaccines over 6.6 years, but data gaps (e.g., 4% shortfall in 2024) limit precision.

Weighing the Data

COVID-19 vaccines report death rates 200-2,000 times higher than traditional vaccines, but FPCI, mandatory reporting, and older recipients may inflate figures. Public health agencies argue this reflects scrutiny, not risk, with benefits reducing severe COVID-19 outcomes. Still, short trials and VAERS signals fuel debate.

Conclusion

COVID-19 vaccines’ VAERS signals (e.g., Janssen’s 3.3 deaths per 100,000 per year) suggest risks obscured by short trials and misclassification, echoing iatrogenic trends of 250,000-783,936 annual deaths. Causation remains elusive, but the scale demands reform. To safeguard trust, regulators must prioritize decade-long studies and death certificate accuracy, addressing both vaccine risks and healthcare’s silent epidemic.

Methodology

Sources: VAERS (1990-2024), CDC coverage data, historical records, The Ethical Skeptic.

Calculations: Deaths per 100,000 doses = (Events / Doses) * 100,000; annualized by years.

Limitations: VAERS’ unverified reports, FPCI, and data gaps.

Additional Context for Non-Recalled Vaccines

MMR (Measles, Mumps, Rubella)
- Launch Date: 1971 (combined vaccine).
- Injuries/Deaths: ~60,000 injuries and ~400 deaths reported to VAERS from 1990-2024.
- Doses: Estimated 600 million doses in the U.S. since 1971 (CDC Pink Book - Measles).
- Rates: ~10 injuries and ~0.07 deaths per 100,000 doses. Rare severe reactions include febrile seizures.
- Notes: No evidence links MMR to autism despite misinformation (CDC MMR Safety). Over 50 years of data show no chronic harms.

- Rates: ~20 injuries and ~0.1 deaths per 100,000 doses. Rare breakthrough infections reported.
- Notes: Highly effective; minor side effects common (CDC Varicella Safety).

General Notes

VAERS Limitations: Reports are unverified and may not indicate causation. Confirmed vaccine-related deaths are a small fraction (e.g., ~9 for Janssen’s TTS) (CDC VAERS Overview).
Dose Estimates: Based on CDC vaccination coverage data and historical trends. Exact totals vary by year and population (CDC Vaccination Coverage).
Pre-VAERS Era: Cutter Polio data is from historical records; no systematic reporting existed (Cutter Incident Report).
Data as of: March 30, 2025, using VAERS data through December 31, 2024, and historical sources.
