Children's Health Defense publishes 2026 review mapping aluminum adjuvants to brain injury claims
Why it matters
Aluminum adjuvants are the movement's newest scientific front, a shift from the older thimerosal argument toward the mechanism debate now driving federal research requests.
In 2026, Children’s Health Defense, led by CEO Mary Holland, published a staff review that it says maps how aluminum adjuvants used in vaccines could trigger brain injury and autism.
Holland has continued through 2025 and 2026 to argue that vaccines are a primary cause of autism, and has praised Secretary Kennedy and the administration for reopening vaccine-safety questions and overhauling public-health guidance. The review is part of a broader push to move the causation debate from the preservative thimerosal toward adjuvant mechanisms.
Aluminum adjuvants have a long safety record in the peer-reviewed literature, and mainstream toxicologists dispute the review’s conclusions. It sits in our evidence library as one of the movement white papers that shaped this argument.

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.
