In late May, when the Trump administration announced a call for new research into the causes of autism, many scientists worried that political agendas, particularly those driven by anti-vaccine sentiment, would dictate which projects received funding.
The proposal process itself seemed unusually controlled, granting health officials more sway than typical over the selection. Furthermore, researchers were given only a few weeks to submit their study plans.
Given that Health Secretary Robert F. Kennedy Jr. was actively promoting the discredited theory linking vaccines to autism, many prospective researchers publicly expressed concern that the Trump administration might only approve projects supporting its preconceived notions.
However, a sense of cautious optimism emerged this week. The 13 projects ultimately selected for funding by the National Institutes of Health proved to be quite different from what was anticipated.
These projects, collectively receiving an impressive $50 million, are based on diverse patient data and rooted in established, trustworthy autism science. Their focus is on understanding the intricate interplay between robust genetic factors and environmental influences in determining an individual’s risk of autism.
In essence, these funded initiatives stand in stark contrast to the week’s startling White House news briefing, which featured unsubstantiated claims about Tylenol causing autism and a flurry of discredited theories suggesting childhood vaccines are dangerous and have increased autism rates.
Alycia Halladay, chief science officer at the Autism Science Foundation, shared her enthusiasm: “We’re very optimistic that these projects will yield crucial insights, regardless of the specific questions they address.”
She added that the selected research spans a wide range of topics, including “everything from environmental toxicants to nutritional impacts and early contextual factors like socioeconomic status.”
On Monday, Dr. Jay Bhattacharya, the esteemed director of the NIH – the world’s leading funder of medical research – joined Mr. Trump and Mr. Kennedy at the White House to officially announce these research awards.
However, Dr. Bhattacharya’s announcement was largely overshadowed by President Trump’s emphatic warnings regarding acetaminophen, the active ingredient in Tylenol, and childhood vaccines.
Many autism scientists were dismayed by the President’s pronouncements. While they welcomed the newly funded NIH projects, a broader skepticism lingered regarding the Trump administration’s overall direction for autism research.
This broader concern includes a controversial vaccine safety review, which Mr. Kennedy assigned to David Geier, a known proponent of the anti-vaccine movement and a publicizer of the thoroughly debunked theory linking vaccines to autism.
Adding to the complex landscape, the Centers for Disease Control and Prevention recently indicated its intent to grant a contract to Rensselaer Polytechnic Institute in New York for investigating a potential vaccine-autism link.
Earlier this year, numerous autism researchers experienced cuts or delays in their federal funding as the Trump administration reportedly shifted priorities away from studies on topics such as gender and diversity.
Nevertheless, the NIH’s Autism Data Science Initiative currently provides researchers with a degree of comfort regarding the field’s future. Dr. Bhattacharya noted that over 250 research teams had applied for this funding opportunity.
Dr. Judith S. Miller, an associate professor at the Center for Autism Research at Children’s Hospital of Philadelphia, co-leads one of the funded teams. Their work will delve into how genetic and environmental factors interact in relation to autism.
Her team’s investigation encompasses various areas, including shifts in autism diagnostic criteria, air and water quality, access to green spaces, the impact of poverty, and the effectiveness of early childhood interventions.
Dr. Miller highlighted the known genetic aspects: “We understand there’s a significant genetic component, accounting for approximately 80 percent of identifiable autism causes. However, merely knowing the genetic cause doesn’t fully explain the long-term outcomes or how to best support each individual.”
The Philadelphia-based team utilizes an extensive collection of maternal and childhood health data. Dr. Miller confirmed that researchers will be able to maintain strict confidentiality of patient data, allaying previous concerns about a potential federal registry for autistic individuals.
Jonathan Sebat, a prominent figure in autism genetics at the University of California, San Diego, also received funding. His team aims to leverage genetic insights to explore the influence of environmental exposures on autism diagnoses.
Initially, he worried that the swift federal review process would compromise the quality of evaluation. However, he noted, “those fears were baseless; the applications underwent a truly rigorous review.”
Dr. Sebat explained that his project is designed to clarify the connections between environmental factors and autism, which have been hinted at in other studies.
“The underlying mechanism for these correlations remains unclear,” he stated. “Autism genetics is a crucial part of the puzzle that we understand well.” This understanding, he believes, helps “the other elements, including the environment, to align.”
Additional projects will investigate dietary and chemical exposures, as well as factors that predict better outcomes for children with autism.
Autism specialists expressed astonishment at the stark contrast between the unverified theories promoted by Mr. Trump on Monday and the sound, evidence-based research initiatives advanced by another branch of his administration.
“To me, they hail from entirely different universes,” remarked Helen Tager-Flusberg, director of Boston University’s Center for Autism Research Excellence and founder of the Coalition of Autism Scientists. “This represents genuinely serious, progressive, exciting, rigorous, gold-standard science.”
