My career in primary care began in 1998, the same year Andrew Wakefield published a study that would have lasting negative effects. The article in *The Lancet* falsely linked the MMR vaccine to autism. Its methodological flaws were obvious: it used a small sample size (only 12 children) and failed to establish causation. Subsequent research definitively refuted Wakefield’s claims. However, for a decade, I spent time addressing Wakefield’s misinformation with nearly every family before their child received the MMR vaccine. I carefully explained the flaws in Wakefield’s work and presented the overwhelming evidence contradicting his conclusions.
A significant turning point occurred in February 2010: *The Lancet* retracted the study due to manipulated data. Wakefield’s research was deemed fraudulent, and his medical license was revoked. In my practice, parental concerns about MMR and autism decreased. I could confidently cite numerous studies disproving the link and highlight the discrediting of Wakefield’s paper.
Now, it feels like we have regressed. The false claim, despite being debunked 15 years ago, is resurfacing. With Robert Kennedy Jr.’s nomination for HHS Secretary, the myth is gaining traction, seemingly disregarding scientific evidence and amplified by social media.
During his January 30th confirmation hearing, Kennedy refused to acknowledge studies showing no link between vaccines and autism. The discredited Wakefield study was even referenced. Senator Maggie Hassan accurately summarized Kennedy’s stance as repeatedly sowing doubt.
Kennedy’s disregard for scientific evidence has had real-world consequences. His 2019 visit to Samoa exacerbated vaccine hesitancy, contributing to a measles outbreak that resulted in 83 deaths, primarily children. An HHS Secretary prioritizing myths over science would be catastrophic for U.S. vaccination programs.
I understand the persistence of such myths, even those thoroughly debunked. Parents want to understand why conditions like autism occur. They strive to make every decision perfectly, from car seats to food choices, in the effort to protect their children.
Parents eventually realize they cannot protect their children from everything. This is a fundamental parental insecurity: even with the best efforts, children can still develop illnesses. This is deeply unsettling.
The vaccine-autism myth exploits this parental vulnerability. It falsely offers the hope of preventing autism through vaccine refusal. In the absence of definitive autism causes, this false certainty is appealing. Kennedy and his allies capitalize on this, implying any explanation is better than none. Myths fill the void of the unknown.
Pediatricians, like parents, will do anything to protect children. Safe and effective vaccines are our most effective tool to prevent serious illness. Vaccines have eradicated diseases like polio and diphtheria in the U.S. The measles vaccine alone has saved over 90 million lives globally.
I regularly remind parents that nothing compares to the benefits of vaccination. No other measure provides the same protection from deadly disease. The best gift we can give children is complete childhood immunizations.
This isn’t to discourage questioning vaccine efficacy and safety. Questioning is essential to the scientific method. But we must also heed the evidence.
While we don’t fully understand autism’s origins, the MMR vaccine is not a cause. This has been clear for decades. The myth’s resurgence shouldn’t overshadow the established scientific consensus.
Powerful figures are distorting the truth about vaccines, to everyone’s detriment. Pediatricians must continue countering these myths with evidence-based facts.
