Episode notes

In this episode of Wellness Unmasked, Dr. Nicole Saphier breaks down the latest public health headlines shaping the national conversation on vaccines, infectious disease, and weight-loss medications.

First, Dr. Saphier examines the rapid rise in measles cases across the United States, with more than 1,000 infections already reported in early 2026. After being declared eliminated in 2000, measles is now making a troubling comeback as vaccination rates decline and outbreaks spread across multiple states. She explains why measles remains one of the most contagious viruses in the world, what the CDC’s new messaging under Acting Director Dr. Jay Bhattacharya means, and why the MMR vaccine remains about 97% effective at preventing infection.

Dr. Saphier also discusses the broader issue of public trust in vaccines and public health after COVID-19, highlighting the balance between medical freedom, informed consent, and transparent science. Why are vaccination rates falling? What risks does measles actually pose beyond death? And what does responsible public health messaging look like in 2026?

Then, she turns to another major health story: the FDA’s warning to more than 30 telehealth companies marketing compounded versions of popular GLP-1 weight-loss drugs like semaglutide. Dr. Saphier explains why regulators say these medications may be misleadingly marketed and potentially unsafe, and why patients should be cautious when purchasing compounded weight-loss drugs from online pharmacies or med spas.

From measles outbreaks and vaccine trust to the booming market for GLP-1 weight loss medications, this episode delivers a clear, balanced look at the most important health issues of the week.
