NEW YORK (AP) — Federal health officials intend to award a contract to Rensselaer Polytechnic Institute to investigate whether there is a link between vaccinations and autism, according to a government procurement notice.

The Troy, New York, engineering school is getting the no-bid contract because of its “unique ability” to link data on children and mothers, according to the notice posted this week.

Officials at the Department of Health and Human Services did not immediately respond to questions about the notice, including how much the contract is for or what exactly the researchers intend to do.

U.S. Health Secretary Robert F. Kennedy Jr., a leading voice in the antivaccine movement before President Donald Trump selected him to oversee federal health agencies, announced in April a “massive testing and research effort” to determine the cause of autism by this month. He has repeatedly tried to link vaccines to the condition.

An RPI biotech engineering professor, Juergen Hahn, has used artificial intelligence and machine learning techniques to look for patterns in blood samples of children with autism. Hahn “is renowned for the quality and rigor of his research,” RPI officials said in a statement acknowledging the intended grant.

“If this project is awarded, he intends to publish the results of his work at the conclusion of the project,” the statement added.

The Associated Press left messages seeking comment from Hahn.

The notice raises many questions, said Alycia Halladay, who oversees research activities and grants for the Autism Science Foundation.

RPI is not known in the field as having any special access to data on this kind of question and “wouldn’t be the obvious choice,” Halladay said.

It’s also not clear how the contract fits into other autism research that the government may be planning, she said.

But perhaps the biggest question is why money is being spent on such a study at all, she added.

Scientists have ruled out a link between vaccines and autism, finding no evidence of increased rates of autism among those who are vaccinated compared with those who are not.

“The question has been studied for 20 years, multiple times by researchers around the world using millions of people, and there has never been a credible association found between vaccines and autism,” Halladay said.

Those who have spent decades researching autism have found no single cause. Genetics play a role, and other factors include the age of a child’s father, the mother’s weight, and whether she had diabetes or was exposed to certain chemicals.

Whatever amount is being spent on the project could instead be going to “other important research questions,” including studies of genetics and environmental factors, Halladay said.

“I think that’s the most frustrating part,” she said.

For months, HHS officials have been trying to use vaccine safety data compiled by the CDC to look for harms that might be tied to shots. Kennedy has accused CDC leaders of stonewalling those efforts, but the actual obstacle has been something else, said one former federal health official familiar with the situation, speaking on condition of anonymity for fear of retaliation.

About a dozen medical research organizations collect the vaccine safety data and report it to the CDC. Contracts that stretch back nearly two decades give those entities — not the CDC — control over the data, and HHS has not yet been able to get it, the official said.
