The power of influence can be a double-edged sword, and some ex-anti-vax moms are learning this the hard way.
A Wake-Up Call for Moms
Heather Simpson, a mom to an eight-year-old, is one of many who are rethinking their stance on vaccines. Her journey into the anti-vaccine movement began with a simple search for healthy pregnancy tips, but it led her down a dangerous path.
The Kennedy Connection
Simpson was drawn into the movement by none other than Robert F. Kennedy Jr., a prominent figure who founded Children's Health Defense. This nonprofit has been identified as a major source of false and misleading claims about vaccines, with a global impact.
Legal Battles and Lost Causes
Over time, Children's Health Defense has filed numerous lawsuits challenging vaccine policies. One notable case was in 2019, when they took on New York's school vaccine requirements following a measles outbreak. However, they lost the case, but that didn't stop the spread of misinformation.
The Anti-Vax Influencer Effect
Simpson became an anti-vax influencer herself, even going as far as dressing up as the measles virus for Halloween. But here's where it gets controversial: after the first measles-related death of a six-year-old in two decades, anti-vax influencers reframed this tragedy to push their agenda against the measles, mumps, and rubella (MMR) vaccine.
A Shift in Perspective
Dr. Leslie Treece, a pediatrician in Tennessee, has seen the impact of this misinformation firsthand, with an increase in parents refusing to vaccinate their children. However, she predicts a shift back towards vaccines as outbreaks become more common.
Simpson's own perspective began to change during the pandemic. After supporting mask-wearing, she decided to consult a specialist about anti-vaccine claims. When the specialist debunked a common myth about emulsifiers in vaccines, Simpson started researching biology and questioning her beliefs.
Back to the Vax
Simpson co-founded the group and podcast "Back to the Vax" with Lydia Greene, another mom and former anti-vaxxer. Greene, a mother of three, described herself as a "crunchy mom," embracing a holistic and natural approach to health. She was drawn to Kennedy's "Make America Healthy Again" campaign, but now she sees the movement differently.
The Impact of RFK Jr.'s Appointment
Since RFK Jr. became the Secretary of the U.S. Department of Health and Human Services, he has made several controversial moves. He changed COVID vaccine eligibility rules, replaced key committee members with vaccine skeptics, cut funding for mRNA vaccine development, and even launched an investigation into a debunked link between vaccines and autism.
Health officials are concerned that this mixed messaging will lead to lower vaccination rates. Michael Osterholm, an epidemiologist, warns that the myths and disinformation coming from the administration will confuse parents and consumers, impacting vaccination rates.
A Sobering Reality
Lydia Greene believes that the only way this situation will change is when children start dying from vaccine-preventable diseases. In 2025, the U.S. reached a tragic milestone with the highest number of reported measles cases since the disease was declared eliminated in 2000. The CDC has confirmed three deaths so far.
Greene reflects on her own journey, feeling a sense of guilt for wishing for this outcome when she was an anti-vaxxer. She now watches the disaster unfold and hopes others will learn from these tragic events.
