Important: VAERS reports alone cannot determine if a vaccine caused an adverse event. Reports may contain incomplete, inaccurate, or unverified information. Correlation does not equal causation.
In-depth, context-rich analysis of VAERS data. Every article presents the numbers with appropriate context, limitations, and nuance. Neither pro-vax nor anti-vax — just transparent data journalism.
The most critical limitation: raw numbers are meaningless without context
Key finding: 670+ million COVID doses make raw report counts misleading without proper denominators
Stimulated reporting, awareness bias, and media influence on VAERS data
Key finding: 2021 saw a 25x spike in reports, demonstrating massive stimulated reporting
How the pandemic changed vaccine adverse event reporting forever
Key finding: 768,706 reports in 2021 alone — more than the previous 10 years combined
Analysis of onset timing patterns across all vaccines
Key finding: 73% of adverse events occur within 3 days of vaccination
Comparing adverse event patterns across COVID-19 vaccine doses
Key finding: Second doses generate 130% more reports than first doses
Analysis of recovery status in VAERS reports
Key finding: 68% of reports indicate recovery, but context about "not recovered" is essential
Why lot analysis is misleading without proper context
Key finding: 4,414 COVID lots with reports, but raw counts cannot determine safety
Analysis of co-administration patterns and safety
Key finding: 1,514 vaccine combinations reported, reflecting standard medical practice
Understanding prenatal vaccination and background birth defect rates
Key finding: 41 vaccines with birth defect reports, but 3-4% background rate is key context
Analysis of hospitalization duration patterns
Key finding: 72% of hospitalizations last 3 days or fewer
Understanding reporting sources and patterns
Key finding: Private practice dominates reporting, reflecting where most vaccines are given
Who reports the most, and who has the most serious outcomes?
Key finding: Adults 65+ account for 56% of all death reports despite being 20% of total reports
Why 59% of VAERS reports come from women
Key finding: Women report nearly twice as often as men across all vaccine types
From 2,214 reports in 1990 to the COVID-era surge and return to baseline
Key finding: Post-COVID reporting has declined 93% from the 2021 peak
Understanding the most closely-watched vaccine safety signal
Key finding: 5,540 myocarditis reports, with COVID-19 vaccines accounting for the vast majority
What "death reported to VAERS" actually means — and doesn't mean
Key finding: 27,732 death reports over 35 years, but context is everything

Key finding: 56% of death reports come from the 65+ age group despite being ~20% of total reports
Side-by-side comparison of the two most widely administered vaccine types
Key finding: COVID-19 vaccines have far more reports, but context around dose volume is essential
Who dominates VAERS reporting and what that means
Key finding: Top 5 manufacturers account for the vast majority of all reports
State-level reporting patterns and per-capita analysis
Key finding: Population drives raw volume, but per-capita reveals reporting culture differences
Understanding the spectrum of adverse event severity in VAERS
Key finding: The majority of VAERS reports describe mild, expected reactions like fever and fatigue
