NIH finalizes its $51 million autism research initiative: 13 projects, none on vaccines
Why it matters
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.
The National Institutes of Health has finalized the Autism Data Science Initiative, committing roughly $51 million across 13 research projects that will study the causes and prevalence of autism using existing large health datasets. The awards grew out of the initiative the administration first announced in September 2025.
None of the 13 funded projects are designed to examine vaccines. That is a distinct effort from the no-bid contract the CDC signaled it would award to Rensselaer Polytechnic Institute, which is specifically framed around a potential vaccine-autism association. As of late September 2026, no findings from the Rensselaer contract have been released.
We are keeping the two efforts clearly separated here, because they are easy to conflate and are frequently reported as one. When results from either the data-science awards or the Rensselaer contract are published, we will link the primary documents directly rather than summarize the coverage.

New McCullough Foundation study: COVID-vaccinated children show higher odds of autism and ADHD in federal survey data
This is the McCullough Foundation’s newest paper, posted today, and it uses the federal government’s own National Health Interview Survey rather than a private dataset. That makes it easy for anyone, including HHS, to check. It is a preprint and has not been peer-reviewed yet.
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.
