Katie Miller discussed her family’s vaccination status on the latest episode of her podcast, revealing that her youngest son, with White House deputy chief of staff Stephen Miller, isn’t vaccinated — and claiming he could put “dirt in his mouth” and “never” get sick.
“I think more young moms, as they start asking the questions, are seeing what you and I both see, which is healthy children can do a lot better not being vaccinated,” Miller told guest Jenny McCarthy, a former model, actor and a staunch anti-vaccine activist.
Miller, a former deputy press secretary to President Donald Trump and proponent of the “Make America Healthy Again” movement spearheaded by Health and Human Services Secretary Robert F. Kennedy Jr., went on to divulge some personal information.
“I haven’t talked about this, but my oldest child is fully vaccinated,” Miller said. “My youngest child is not vaccinated at all. My oldest child had milk soy protein allergy, right? And we had struggles breastfeeding. My third child was fully breastfed until age 1.”
She continued, “He is my healthiest child who never, ever gets sick. He’s never been on antibiotics. He is like, every day I could put, like, dirt in his mouth and he will not get ill.”
Vaccines have been credited with saving 154 million lives over the past 50 years, with 101 million of those being infants, according to the World Health Organization. And several large-scale studies investigating an alleged link between childhood vaccines and allergies have debunked correlations such as Miller’s.
The MAGA acolyte received no pushback from her like-minded guest, who previously linked the MMR (measles, mumps and rubella) vaccine to her son’s autism — and published the 2007 book, “Louder than Words: A Mother’s Journey in Healing Autism.” (The alleged link between vaccines and autism has been debunked time and again by experts and studies around the world.)
“Correct,” McCarthy told Miller. “It really is true. ‘An Inconvenient Study’ is a documentary that you should watch, and they did that study, but they won’t put it out there, showing the chronic illness of the percentage is, you would be mind-boggled.”
The 2020 study in question, “Impact of Childhood Vaccination on Short and Long-Term Chronic Health Outcomes in Children: A Birth Cohort Study,” was only released after a U.S. Senate hearing in 2025 on the supposed “corruption” of the health system.
Anti-vaccine activists falsely believe it was intentionally “buried.” The study, which looked at more than 18,000 children born at Henry Ford Hospital between 2000 and 2016, was deemed wholly “flawed” and incomplete.

“The data that has been used is not complete data,” Dr. Adnan Munkarah told Michigan Public Radio in November. “There is a significant discrepancy between the groups in that study. The analysis that was done was not the correct analysis.”
McCarthy also has championed chelation therapy, a medical procedure that removes heavy metals from the body, for helping her son “recover” from his autism. There is currently no cure for the lifelong neurodevelopmental condition, according to the Mayo Clinic.
While chelation therapy has been approved by the U.S. Food and Drug Administration for treating heavy metal poisoning, the agency has also issued warnings about unapproved uses — specifically citing autism spectrum disorder as an example.
McCarthy has denied that her son was simply misdiagnosed and told Miller that a doctor recently described him as “the healthiest 23-year-old” he’s ever seen.
The actress is an advocate of the anti-vaccine movement that has contributed to a recent resurgence in measles — the worst in 30 years in the U.S.
And the Trump administration on Monday announced that it will decrease the number of vaccines in the childhood immunization schedule, prompting a social media post from Trump that shared what doctors are calling “fictitious” and “purposefully misleading” information.
Katie Miller and Stephen Miller are expecting their fourth child together. They announced as much with a none-too-subtle photo of them posing at the Mar-a-Lago New Year’s party, with Katie Miller cradling her pregnancy bump on the red carpet.
