Bronwyn Hancock is an Australian systems analyst with a Bachelor of Science degree specializing in computing who transitioned from a 16-year career in programming to become a dedicated researcher in natural health and vaccine safety. She produced the documentary ‘Vaccination: The Hidden Truth’ in 1998 and authored ‘A Fatal Error,’ applying her analytical expertise to statistical analysis of vaccine outcomes. Hancock presents compelling statistical analysis demonstrating that across all vaccines on the US childhood schedule, the risk of death or serious injury from vaccination exceeds the risk from remaining unvaccinated. Her research reveals that for diseases like Hepatitis A, vaccinated individuals face 23 times greater risk of death compared to unvaccinated individuals.

Summary
Bronwyn Hancock testifies about her comprehensive statistical analysis comparing vaccination risks to disease risks for the US childhood vaccine schedule. She explains her methodology involves calculating disease rates in unvaccinated populations using government data on disease notifications, vaccination coverage, and vaccine effectiveness, then comparing these to serious adverse events from vaccines reported in VAERS database. Her analysis accounts for the Lazarus study’s finding of 100-fold underreporting in VAERS and applies WHO causality criteria, considering only ‘certain’ and ‘probable’ causally-linked events. The results show dramatically higher risks from vaccination compared to remaining unvaccinated across all analyzed vaccines. For example, Hepatitis A vaccination carries 23 times greater death risk than non-vaccination, while other vaccines show similarly elevated risk ratios. Hancock emphasizes that most vaccine-preventable diseases are already rare, setting a high safety bar for vaccines. She notes her calculations are conservative as they accept claimed vaccine effectiveness rates based on antibody levels, despite research showing people with high antibodies can still contract severe disease. She advocates for natural health approaches including vitamin C megadoses, citing a New Zealand case where a dying patient recovered after vitamin C administration despite medical resistance. Hancock suggests medical politics and pharmaceutical industry interests prevent proper education about health and block dissemination of risk-benefit analyses like hers. She believes physicians need this information to properly advise patients for true informed consent regarding childhood vaccinations.
Credentials
Bronwyn Edith Hancock holds a Bachelor of Science degree specializing in computing from 1982, bringing a strong foundation in mathematics and analytical thinking to her work. After spending 16 years as a systems analyst and programmer, she redirected her technical expertise toward investigating natural health and vaccine safety. Her transition into health research was marked by the production of the documentary ‘Vaccination: The Hidden Truth’ in 1998, followed by her book ‘A Fatal Error.’ Since 2014, she has conducted detailed statistical comparisons between government-reported vaccine outcomes and disease mortality rates.

Her research reveals that for diseases like Hepatitis A, vaccinated individuals face 23 times greater risk of death compared to unvaccinated individuals. She emphasizes that most vaccine-preventable diseases are already rare and that medical professionals often overestimate disease risk while underestimating vaccine risks. Her methodology involves calculating disease rates in unvaccinated populations using government data, then comparing these to serious adverse events from vaccines reported in VAERS database, accounting for underreporting and applying WHO causality criteria.
