The record behind the witness: Hulscher's 39 studies and why legislators keep calling him
Why it matters
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.
Nicolas Hulscher holds a Master of Public Health in epidemiology from the University of Michigan and serves as an administrator at the McCullough Foundation. By his own public accounting, he has authored 39 studies, 32 of them peer-reviewed, spanning vaccine safety, cardiovascular pathology, genomic dysregulation, infectious disease, autism determinants, and cancer therapeutics.
That output is why his name keeps surfacing in the legislative record. In September 2025 he testified before a U.S. Senate hearing on vaccination and chronic disease in children; a year later he appeared before the Michigan House Oversight Subcommittee to present a reanalysis of Henry Ford Health data. He was also the lead author on the Foundation's Determinants of Autism Spectrum Disorder report, the document that names the early combination schedule as the leading modifiable risk factor.
His work is contested. Independent researchers have challenged the methodology behind the vaccinated-versus-unvaccinated comparisons, and mainstream medical bodies maintain there is no established causal link between vaccines and autism. We report both the work and the objections to it, and we link his publications so you can weigh them yourself. His stated aim, in his own words, is to give people accurate data so they can make informed health decisions.

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 It is a preprint and has not been peer-reviewed yet.
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.
