A new mRNA flu vaccine is here — and social media is already misreading the data. Meanwhile, childhood vaccine exemptions are rising, measles is spreading, Fauci is back in the headlines, and politics keeps colliding with public health. Dr. Terry Simpson breaks down what the evidence actually shows, plus new studies on COVID, dementia, hepatitis immunity, sugary drinks, and cervical cancer. This is a public episode.

Scientists used artificial intelligence to design genetic codes that produced functioning viruses never before found in nature. They infect bacteria, not humans—but the breakthrough raises an obvious question: could we someday design a virus that infects people? Dr. Terry Simpson explains what scientists accomplished, why we could not do this in 2019, and what it does—and does not—tell us about claims that COVID-19 was designed. Plus, measles costs millions, Cyclospora declines, the first mRNA flu vaccine arrives, and new studies examine testosterone, dementia, vitamin D, vegan diets, and tirzepatide.

This week on The Unfiltered MD, Dr. Terry Simpson explains the rapidly growing Cyclospora outbreak, why "explosive diarrhea" has become the biggest infectious disease story of the week, how this microscopic parasite spreads through fresh produce, why yesterday's salad probably wasn't the culprit, and what actually works to prevent infection. He also reviews new research on coffee and liver health, the Mediterranean diet and dementia prevention, obesity treatment, GLP-1 medications, measles, vaccines, and the latest peptide controversy.

Senator Rand Paul says Anthony Fauci lied to Congress. Tulsi Gabbard says the United States funded dangerous gain-of-function laboratories around the world. As a former molecular virologist who performed one of the earliest gain-of-function experiments before becoming a surgeon, I read the grants, testimony, and supporting papers to answer one question: What do they actually say? In this episode of The Unfiltered MD, we explore gain-of-function research, NIH grant review, biosafety laboratories, Ebola preparedness, and why understanding the science matters more than the headlines.

Everyone seems to be selling hydration these days. Electrolyte packets, Himalayan salt, trace minerals, and powders that promise better energy, better performance, and better health. But do most people actually need them?In this episode of The Unfiltered MD, Dr. Terry Simpson looks at the evidence behind the hydration industry. We explore what the DASH-Sodium Trial taught us about salt and blood pressure, why sports scientists have been measuring sweat for decades, what Gatorade actually got right, and why glucose—not magnesium—is often the unsung hero of effective rehydration.Along the way we’ll separate physiology from marketing, explain when products like Pedialyte make sense, and discuss why many healthy people are spending money on a problem they don’t actually have.Your kidneys are smarter than most influencers. Let’s talk about it. This is a public episode. If you'd like to discuss this with other subscribers or get access to bonus episodes, visit www.drsimpson.com/subscribe

This week on Dr. Simpson: The Unfiltered MD, we explore the tale of two peptides. On one side are GLP-1 medications like Zepbound and Ozempic, which continue to show benefits far beyond weight loss, including promising findings in cancer risk, kidney disease, psoriasis, and arthritis. On the other side are the unproven peptides sold online and promoted by wellness influencers, gym bros, and even some physicians despite little evidence of safety or effectiveness. We also discuss why clinical trials matter, what Vioxx taught medicine about drug safety, declining alcohol consumption, measles, RSV vaccines, wildfire smoke, and why the same evidentiary standard should apply to every health claim.

This week on Dr. Simpson Unfiltered, we lead with the Ebola outbreak in Central Africa and ask a larger question: why do we spend billions preparing for public health emergencies if we’re reluctant to use the systems we built? Dr. Simpson examines the U.S. response, the controversy over a proposed Ebola facility in Kenya, and why specialized biocontainment units at places like Emory and Nebraska exist for moments exactly like this.Also this week: an experimental gene-editing treatment that may permanently lower LDL cholesterol after a single infusion, new evidence suggesting long COVID may be far more common than official estimates, the FDA’s review of reports of child deaths following COVID vaccination, and research showing that better cardiovascular health is associated with lower risk of severe COVID infection.From outbreak preparedness to cutting-edge genetic medicine, Dr. Simpson separates evidence from headlines and explains what these stories mean for patients, physicians, and the future of public health.Data beats dogma.
