#029 - The Truth About Vaccines, Cancer & Living Longer - John Tregoning
from Philomath · host Richie O'Brien
John Tregoning is a Professor of Vaccine Immunology at Imperial College London discussing how the immune system works, what vaccines actually contain, and why so many health myths persist. We explore flu and COVID vaccines, side effects versus real-world risk, fertility and autism claims, and how misinformation spreads during periods of fear and uncertainty. John explains why the speed of COVID vaccine development was not unsafe, how risk should be properly balanced, and why trusted sources matter more than viral headlines.The conversation also dives into cancer, aging, and long-term health. We discuss what cancer actually is, why diagnosis rates are rising, the importance of early detection and screening, and why many people delay getting checked. John shares his personal experience with skin cancer, the psychology of health avoidance, prevention strategies, hearing loss and dementia risk, lifestyle factors that improve longevity, and why doing more of what you enjoy with people you love may be one of the most powerful health tools we have.- Get in contact below:YouTube: Richie O'Brien - YouTubeInstagram: https://www.instagram.com/richieobrienx/TikTok: https://www.tiktok.com/@richieobrienxLinkedIn: https://www.linkedin.com/in/richieobrienx/-Find John below:LinkedIn: https://www.linkedin.com/in/john-tregoning/-Timestamps:(00:00) The Quest for Immortality(03:08) Understanding Mortality and Aging(06:03) The Impact of Life Experiences on Perception of Age(09:05) The Future of Medicine and Disease(11:58) Non-Infectious vs Infectious Diseases(14:57) The Role of Genetics in Health(17:59) Lifestyle Choices for Longevity(21:01) The Importance of Exercise(24:00) The Dangers of Smoking and Vaping(26:59) Alcohol Consumption and Health Risks(33:21) Cultural Attitudes Towards Drinking(36:02) The Importance of Social Connections(42:51) The Role of Vaccination in Health(57:33) Understanding Cancer and Early Detection
