Diphtheria Presentation + Q&A Featuring Brian Hooker, Ph.D.

The Diphtheria Vaccine: Revisiting the Science and Safety | Presented by Brian Hooker, Ph.D.

In this presentation, Dr. Hooker delves into the history, composition, and safety profile of the diphtheria vaccine, with a critical lens on the current data.

Drawing on decades of research and pharmacovigilance analysis, he highlights areas where scientific assumptions may not align with long-term outcomes, especially for children.

He explores:

• The historical context and decline of diphtheria prior to widespread vaccination
• Known adverse events associated with the diphtheria toxoid and its combination vaccines (like DTaP)
• Data gaps in long-term safety trials and the limitations of passive reporting systems
• The use of aluminum adjuvants and their potential cumulative impact on the developing immune system
• Ethical concerns around the ongoing use of combination shots without disaggregated safety review

Dr. Hooker presents a research-driven, principled challenge to the assumption that “older vaccines” are inherently safer—urging a fresh, science-first evaluation of childhood vaccine policies.

Live Q&A – Diphtheria: Disease, Data & the Decline of Risk with Robyn Chuter, Professor Brian Hooker, and Greg Beattie

In this recorded live Q&A, Robyn Chuter moderates a rich and insightful discussion with two leading experts who bring scientific rigor, historical analysis, and public health perspective to the topic of diphtheria. Responding to real-time audience questions, the panel unpacks both the history and modern narrative around this once-feared disease—offering clarity for families navigating today’s vaccine schedule.

Their exchange offers a rare blend of compassion and candor—demystifying diphtheria, exploring vaccine efficacy, and questioning whether the threat still justifies the policy.

Topics include:

• How dangerous is diphtheria in today’s world?
• What does the data show about vaccine effectiveness and duration of immunity?
• What role do hygiene, nutrition, and modern medicine play in diphtheria’s decline?
• Should parents still be concerned—or are we vaccinating for a threat that no longer exists?

This is essential viewing for anyone wanting to better understand diphtheria—not through fear, but through facts. If you’ve ever felt unsure, overwhelmed, or unheard in conversations about vaccines, this Q&A invites you into a more honest and informed dialogue.
