Autism and vaccines recur across Kennedy's congressional hearings
Why it matters
The autism-vaccine question is no longer confined to advocacy conferences. It now surfaces in sworn testimony before House and Senate committees, and how the Secretary and other nominees answer under oath goes straight into the public record.

The autism-and-vaccine question has repeatedly surfaced in congressional hearings involving HHS Secretary Robert F. Kennedy Jr. and administration nominees. In his September 4, 2025 Senate Finance Committee testimony, Kennedy faced pointed questions about his vaccine-safety rhetoric and his plans to overhaul the CDC.
At an April 17, 2026 House Education and Workforce Committee hearing, Kennedy defended his emphasis on environmental causes of autism. And in a February 2026 Senate HELP Committee hearing, Surgeon General nominee Casey Means declined to state unequivocally that vaccines do not cause autism.
Critics say the recurring exchanges give a scientifically settled question the appearance of an open debate. What matters for the record is that these exchanges happened under oath, before Congress, and sit in the transcript regardless of how any one witness framed them.

NIH finalizes its $51 million autism research initiative: 13 projects, none on vaccines
The administration promised a hard look at what causes autism. The money is now committed, and it is worth being precise about where it went: the largest federal award pool of the year funds thirteen projects, and not one of them studies vaccines. The vaccine question sits with a separate, much smaller contract that has yet to report anything.
Post“Kennedy is the saving grace”: Trump moves to remake the childhood schedule, and what is actually in force
In the span of six weeks the President signed an order cutting routine childhood vaccines from 18 diseases to 11, then stood beside Robert F. Kennedy Jr. and proposed splitting shots into five smaller doses. A viral clip called it a schedule of 72 shots reduced to 11 “by the stroke of a pen.” That is the biggest shift in federal vaccine posture in a generation, and it is also not yet law. Here is the record, and the reaction, side by side.

The record behind the witness: Hulscher's 39 studies and why legislators keep calling him
Nicolas Hulscher has become the reform movement's most-requested expert witness, appearing before both the U.S. Senate and the Michigan House inside a single year. Behind those appearances is a specific, checkable body of published work, and readers deserve to see what it actually consists of rather than take the label 'epidemiologist' on faith.
