    Trump Administration Ends Program Critical to Search for an H.I.V. Vaccine

    The termination is the latest in a series of cuts to H.I.V. research and programs to prevent the disease.The Trump administration has dealt a sharp blow to work on H.I.V. vaccines, terminating a $258 million program whose work was instrumental to the search for a vaccine.Officials from the H.I.V. division of the National Institutes of Health delivered the news on Friday to the program’s two leaders, at Duke University and the Scripps Research Institute.Both teams were collaborating with numerous other research partners. The work was broadly applicable to a wide range of treatments for other illnesses, from Covid drugs to snake antivenom and therapies for autoimmune diseases.“The consortia for H.I.V./AIDS vaccine development and immunology was reviewed by N.I.H. leadership, which does not support it moving forward,” said a senior official at the agency who was not authorized to speak on the matter and asked not to be identified.“N.I.H. expects to be shifting its focus toward using currently available approaches to eliminate H.I.V./AIDS,” the official said.The program’s elimination is the latest in a series of cuts to H.I.V.-related initiatives, and to prevention of the disease in particular. Separately, the N.I.H. also paused funding for a clinical trial of an H.I.V. vaccine made by Moderna.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    RFK Jr. Announces Ban on Food Dyes and Says ‘Sugar Is Poison’

    Health Secretary Robert F. Kennedy Jr. escalated his war against the food industry on Tuesday, declaring that “sugar is poison.”Mr. Kennedy’s comment came during a highly publicized news conference where he also asserted that he has “an understanding” with major food manufacturers to remove petroleum-based food colorings from their products by 2026.No one from the food industry attended the event, and none have publicly agreed to Mr. Kennedy’s demands, although the International Dairy Foods Association has pledged to eliminate artificial colors in milk cheese and yogurt sold to schools as part of the federal lunch and breakfast programs by the start of the 2026 school year.However, Mr. Kennedy and his advisers said that every major food manufacturer and some fast-food companies have contacted the agency looking for guidance.“Four years from now, we are going to have most of these products off the market, or you will know about them when you go to the grocery store,” Mr. Kennedy said.Mr. Kennedy’s push to get food manufacturers to remove dyes from their products is his first effort at sweeping reform of the food industry, which he has long blamed for creating and marketing ultra-processed foods that he says are making Americans obese and contributing to a host of diseases, including diabetes and heart disease.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Trump-Allied Prosecutor Sends Letters to Medical Journals Alleging Bias

    An interim U.S. attorney is demanding information about the selection of research articles and the role of N.I.H. Experts worry this will have a chilling effect on publications.A federal prosecutor has sent letters to at least three medical journals accusing them of political bias and asking a series of probing questions suggesting that the journals mislead readers, suppress opposing viewpoints and are inappropriately swayed by their funders.The letters were signed by Edward Martin Jr., a Republican activist serving as interim U.S. attorney in Washington, D.C. He has been criticized for using his office to target opponents of President Trump.Some scientists and doctors said they viewed the letters as a threat from the Trump administration that could have a chilling effect on what journals publish. The health secretary, Robert F. Kennedy Jr., has said he wants to prosecute medical journals, accusing them of lying to the public and colluding with pharmaceutical companies.One of the letters was sent to the journal Chest, published by the American College of Chest Physicians. The New York Times obtained a copy of the letter.The Times confirmed that at least two other publishers had received nearly identically worded letters, but those publishers would not speak publicly because they feared retribution from the Trump administration.In the letter to Chest, dated Monday, Mr. Martin wrote, “It has been brought to my attention that more and more journals and publications like CHEST Journal are conceding that they are partisans in various scientific debates.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    A Harvard Scientist’s Tuberculosis Research Is Threatened by Trump’s Cuts

    Researchers who have lost funds warned of long-term repercussions, but several said their school should still refuse to comply with the federal government.Dr. Sarah Fortune, an immunologist who spends a lot of time in her laboratory at Harvard, never expected to be caught in a battle with the White House.But early Tuesday morning, she received an official notice to “stop work” on her lab’s federally funded research on tuberculosis, an infectious disease that kills more than a million people a year worldwide.Just hours earlier, the Trump administration had vowed to freeze $2.2 billion in research funding at Harvard. If fully executed, it will be the deepest cut yet in a White House campaign against elite universities that began shortly after President Trump took office in January. Other universities, including Princeton, Cornell and Columbia, have also seen deep cuts to research funding.Dr. Fortune’s contract, a $60 million National Institutes of Health agreement involving Harvard and other universities across the country, appeared to be one of the first projects affected. Stop-work notices also began arriving this week at an obscure Harvard office called “sponsored programs” that coordinates federal research funding.One Harvard professor, David R. Walt, received a notice that his research toward a diagnostic tool for Lou Gehrig’s disease, or A.L.S., must stop immediately. Two other orders will affect research on space travel and radiation sickness, just weeks after the scientist, Dr. Donald E. Ingber, who engineers fake organs that are useful in studies of human illnesses, was approached by the government to expand his work.David R. Walt at his lab at Harvard Medical School, where he does research searching for a diagnostic tool for Lou Gehrig’s disease, or A.L.S.Cody O’Loughlin for The New York TimesWe are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Experts Doubt Kennedy’s Timetable for Finding the Cause of Autism

    The nation’s health secretary announced that he planned to invite scientists to provide answers by September, but specialists consider that target date unrealistic.Robert F. Kennedy Jr., the nation’s health secretary, pledged on Thursday to seek out experts globally to discover the reasons for the increasing rates of autism in the United States.“We’ve launched a massive testing and research effort that’s going to involve hundreds of scientists from around the world,” Mr. Kennedy announced at a cabinet meeting held by President Trump. “By September, we will know what has caused the autism epidemic and we’ll be able to eliminate those exposures.”“There will be no bigger news conference than that,” Mr. Trump replied.But scientists who have worked for decades to find a cause greeted Mr. Kennedy’s predicted timeline with skepticism.They said that a single answer would be hard to identify in a field of possible contributors including pesticides, air pollution and maternal diabetes.Dr. Philip Landrigan, a pediatrician and expert on environmental toxins, pointed to the current mass layoffs and cutbacks for research at Mr. Kennedy’s Department of Health and Human Services as one reason for doubting such quick progress.“Given that a great deal of research on autism and other pediatric diseases in hospitals and medical schools is currently coming to a halt because of federal funding cuts from H.H.S.,” he said, “it is very difficult for me to imagine what profound scientific breakthrough could be achieved between now and September.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Trump’s Nominee for N.I.H. Chief Faces Questions From Senators

    Dr. Jay Bhattacharya, a Stanford University health economist who came to prominence crusading against lockdowns during the coronavirus pandemic, faced questioning from the Senate health committee on Wednesday morning as President Trump’s nominee to direct the National Institutes of Health.The agency, the world’s largest funder of biomedical research, with a $48 billion budget and 27 separate institutes and centers, has been rocked lately by the Trump administration’s efforts to block government spending and shrink the federal work force. Hours before Wednesday’s hearing, the Department of Government Efficiency, the cost-cutting group led by Elon Musk, trumpeted the cancellation of N.I.H. grants.Dr. Bhattacharya, who has a medical degree and is a professor of medicine but has never practiced, has expressed an interest in restructuring the agency and reducing the power of “scientific bureaucrats” who he has said end up “dominating a field for a very long time.”His views on medicine and public health have at times put Dr. Bhattacharya at odds with many of the scientists whose research the N.I.H. oversees.While he has defended vaccines and has said he was dubious that they caused autism, Dr. Bhattacharya told an interviewer last year that he could not rule out a link. “I don’t know that for a fact,” he said. Extensive evidence shows no link between immunizations and autism.Dr. Bhattacharya became a go-to witness in court cases challenging Covid policies, including mask mandates. In several cases, judges said he was disregarding facts or was untrustworthy. His detractors note that while he has published studies on health policy issues — like drug prices and the link between different types of health insurance and H.I.V. deaths — he is not a scientist conducting biomedical research, the core mission of the agency.But supporters have said that Dr. Bhattacharya could bring needed reform to the N.I.H. and have defended some of his contrarian views on Covid.Dr. Bhattacharya burst into the news at the height of the pandemic in October 2020, when he co-wrote an anti-lockdown treatise, the Great Barrington Declaration, that argued for “focused protection” — a strategy that would focus on protecting the elderly and vulnerable while letting the virus spread among younger, healthier people.The nation’s medical leadership, including Dr. Francis S. Collins and Dr. Anthony S. Fauci, then director of the National Institute of Allergy and Infectious Diseases, denounced the plan. Referring to Dr. Bhattacharya and his co-authors as “fringe epidemiologists,” Dr. Collins wrote in an email that “there needs to be a quick and devastating takedown of its premises.”Dr. Collins, who later stepped down as the N.I.H. director to pursue his laboratory research, retired last week in anticipation of Dr. Bhattacharya’s arrival.

    How Trump’s Medical Research Cuts Would Hit Colleges and Hospitals in Every State

    A proposal by the Trump administration to reduce the size of grants for institutions conducting medical research would have far-reaching effects, and not just for elite universities and the coastal states where many are located. Also at risk could be grants from the National Institutes of Health to numerous hospitals that conduct clinical research on […] More
