This week on Highway to Health, Jimmy Mac welcomes Dr. Uli von Andrian, President of the American Association of Immunologists, for a timely and accessible conversation on immunization, adult vaccinations, and how your immune system really works.

Dr. von Andrian breaks down the science in a way that’s easy to understand—covering everything from how vaccines work, why you still need flu or COVID shots even after infection, to the truth behind common vaccine myths. Whether you're a driver on the road or someone looking to take charge of your health, this is a must-watch episode.

This extended edition of Highway to Health brings heart, honesty, and health education front and center. Co-hosts Jimmy Mac and Lindsay Lawler (joining in-studio for the first time from FASTPORT’s New Orleans studios) welcome a powerhouse duo to the mic: Janet Church, CEO of the Sjögren’s Foundation and a Sjögren’s patient herself, and Dr. Don Thomas, leading expert in Sjögren’s and lupus.

In honor of World Sjögren’s Day (July 23), the team unpacks this misunderstood autoimmune disease affecting millions—many undiagnosed, most of them women. What is Sjögren’s? Why is it so often missed? What happens if it goes untreated? From personal stories to medical insight, this episode highlights the urgency of awareness, the power of support, and what listeners can do to help.

Whether you’ve never heard of Sjögren’s or know someone quietly suffering, this is a conversation that makes it real.
