Episode #44: Vaccines

Author: Hannah Wright & Victoria LaFont October 1, 2025 Duration: 35:02

In this episode, Hannah & Victoria speak with Dr. Heather Zwickey about vaccines.

About Dr. Zwickey:

Heather Zwickey earned a Ph.D. in Immunology and Microbiology from the University of Colorado Health Sciences Center with a focus on infectious disease and vaccine development. Dr. Zwickey went on to complete a postdoctoral fellowship and teach at Yale University School of Medicine, where she worked on immunotherapy for cancer.

She was then recruited to the National University of Natural Medicine in Portland, OR, where she launched the Helfgott Research Institute and served as its director for 17 years. In 2009, Dr. Zwickey established the School of Graduate Studies, developing programs in integrative medicine research, nutrition, and global health, among others. As the founding dean of the graduate school, she continues to teach many courses.

Dr. Zwickey currently co-leads an NIH-funded clinical research training program focused on training the next generation of integrative medicine researchers. She teaches at many universities and speaks at conferences worldwide. At Helfgott Research Institute, Dr. Zwickey applies her immunology expertise to natural medicine, with a specific interest in the gut-brain axis in neuroinflammation.

With expertise in infectious disease and vaccine development, Dr. Zwickey has been sought out for her knowledge regarding COVID-19. She’s spoken on more than 50 podcasts, written articles, and been a resource for people with tough questions.

They cover these questions:

* Do some kids need certain vaccines while others don’t?

* What is the optimal schedule for a healthy baby, toddler, or child based on the changes occurring in their immune system?

* What determines the current vaccine schedule?

* Is there a greater potential for adverse effects when multiple vaccines are given in tandem, ex., MMR?

* What might make some children or adults more susceptible to adverse effects compared to others?

* Why has the vaccine schedule changed so much in the past 25 years?

* What would you say to a parent who is hesitant to vaccinate their child because they are worried about vaccine side effects?

* What would you say to someone who is angry that some people choose not to vaccinate their children?

* How do you think vaccines have affected health outcomes over the last 100 years?

Note: We didn’t record with video because Dr. Zwickey was on hour 14 of interviews the day we spoke.
