CDC Updates Autism Webpage, HHS Launches Reassessment
This week, the Centers for Disease Control and Prevention quietly updated its vaccine safety webpage regarding autism. The new wording states that the claim “vaccines do not cause autism” is not an evidence-based claim, as studies have not ruled out the possibility of a link in infants.
The CDC also acknowledged that some studies suggesting potential links were “ignored” by health authorities in past reviews. While the webpage’s headline still reads “Vaccines do not cause autism,” this wording remains due to a legislative agreement with a U.S. Senator.
In parallel, the U.S. Department of Health and Human Services has launched a comprehensive reassessment into the causes of autism, examining biologic mechanisms, potential causal pathways, and gaps in prior research. This marks the first major federal review of autism causes in decades.
What This Means:
1. Transparency and Public Trust Matter
For decades, public health messaging stated a definitive position. The CDC’s update shows that scientific understanding can evolve, and the public needs clear, accurate communication when positions change. Transparency allows families to make decisions based on full information, not outdated claims.
2. Evidence Gaps Highlight the Need for Informed Decision-Making
Acknowledging gaps or unresolved questions does not establish causation. Instead, it underscores why families, healthcare providers, and policymakers need to evaluate information carefully and make decisions with access to complete data.
3. Federal Oversight Is Expanding
HHS’s reassessment demonstrates that federal agencies are reviewing the science more comprehensively than before. Families can expect ongoing updates as new evidence is studied and evaluated.
Why This Matters:
When public health guidance changes, families deserve clear, accurate, and complete information. Transparency allows individuals to make informed decisions with confidence, without coercion or confusion.
Informed Policy Advocates’ Mission:
At IPA, we do not make medical claims or draw conclusions about causation. Our role is to ensure Californians and the public:
Informed Consent – receive full, transparent information to guide their choices
Consumer Protections – are safeguarded when uncertainty exists in scientific research
Civil Rights – can make decisions free from discrimination or coercion
This development is a reminder of why IPA exists. Our work ensures that families, educators, and policymakers have the tools to navigate evolving public health guidance with clarity and confidence.
