Hulscher on X: “first-ever” study of childhood COVID vaccination and autism in federal survey data
Why it matters
This is the post that took the McCullough Foundation’s new NHIS paper viral. Read it alongside our write-up of the study, which explains what the survey data can and cannot show.

Nicolas Hulscher announced the preprint on X on October 5, 2026, describing it as the first study to examine childhood COVID-19 vaccination and autism outcomes in nationally representative U.S. government data from 21,990 children. He also published a longer write-up on his Substack, The Focal Points.
The paper is a preprint and reports an association in cross-sectional survey data, not proof of cause. Our full summary is linked under Related.

CDC study in Pediatrics: parent-reported autism up 42% in five years, and 120% among preschoolers
This is the federal government’s own survey, published in the flagship pediatrics journal, and it shows autism rising faster than at any point in the CDC’s recent data. Children’s Health Defense asks the question the paper leaves open: what is driving it?

Kennedy launches a federal vaccine-injury push: an NIH clinic, paid VAERS reporting and a rebuilt reporting system
For decades families who reported a reaction after a vaccine were told it was a coincidence. HHS is now building a clinic to study those cases and paying doctors to report them. It is the most concrete step yet toward the vaccine-safety research Kennedy promised.

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 It is a preprint and has not been peer-reviewed yet.
