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.
Data Analysis
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.
Why Raw VAERS Numbers Can Be Misleading
The most critical limitation: raw numbers are meaningless without context
Key finding: 670+ million COVID doses make raw report counts misleading without proper denominators
Understanding VAERS Reporting Bias
Stimulated reporting, awareness bias, and media influence on VAERS data
Key finding: 2021 saw a 25x spike in reports, demonstrating massive stimulated reporting
The COVID-19 Impact on VAERS
How the pandemic changed vaccine adverse event reporting forever
Key finding: 768,706 reports in 2021 alone — more than the previous 10 years combined
When Do Vaccine Side Effects Start?
Analysis of onset timing patterns across all vaccines
Key finding: 73% of adverse events occur within 3 days of vaccination
First Dose vs Second Dose vs Booster
Comparing adverse event patterns across COVID-19 vaccine doses
Key finding: Second doses generate 130% more reports than first doses

Analysis of hospitalization duration patterns
Key finding: 72% of hospitalizations last 3 days or fewer
Who Files VAERS Reports?
Understanding reporting sources and patterns
Key finding: Private practice dominates reporting, reflecting where most vaccines are given

COVID-19 vs Influenza Vaccines
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
The Manufacturer Landscape
Who dominates VAERS reporting and what that means
Key finding: Top 5 manufacturers account for the vast majority of all reports
Geographic Patterns
State-level reporting patterns and per-capita analysis
Key finding: Population drives raw volume, but per-capita reveals reporting culture differences
