Kennedy ends federal mRNA vaccine projects over experts' objections
Aug. 5 (UPI) -- The U.S. Department of Health and Human Services will begin pulling contracts to develop vaccines for respiratory viruses using mRNA technology, which was used for the COVID-19 shot.
Department Secretary Robert F. Kennedy Jr. announced the move in a video posted to X on Tuesday saying that it will terminate 22 contracts worth $500 million after officials determined the "technology poses more risks than benefits for these respiratory viruses."
"Let me be absolutely clear," said Kennedy. "HHS supports safe, effective vaccines for every American who wants them, that's why we're moving beyond the limitations of mRNA for respiratory viruses and investing in better solutions."
The announcement follows other actions by Kennedy, a vocal vaccine critic, to reshape the federal government's approach to public health in ways that have rankled mainstream health experts. Kennedy has replaced members of a vaccine advisory panel with skeptics and stopped recommending COVID-19 inoculations for healthy children, contradicting the U.S. Centers for Disease Control and Prevention's recommendations.
The use of mRNA technology is credited with hastening the end of the COVID-19 pandemic. But its rapid development and the novelty of the technology have left lingering worries over its safety and effectiveness despite reassurances from experts. Like previous moves, Kennedy's decision to end the contracts has drawn criticism from medical and public health experts.
"I've tried to be objective & non-alarmist in response to current HHS actions -- but quite frankly this move is going to cost lives," Dr. Jerome Adams, who served as Surgeon General in the first Trump administration, said in a post on X. "mRNA technology has uses that go far beyond vaccines... and the vaccine they helped develop in record time is credited with saving millions."
Most vaccines have worked by using a weakened or dead virus to trigger a response in a patient's immune system. Vaccines that use messenger RNA, or mRNA, instead use a molecule that causes cells to replicate a part of the virus, triggering an immune response. A new flu vaccine developed by Moderna using the technology has shown promise.
Kennedy said in his announcement that mRNA is ineffective and that vaccines using it encourage new mutations of the virus they are intended to target. He suggested the COVID-19 vaccine prolonged the pandemic and that the department would focus on research on "whole virus vaccines and novel platforms."
Dr. Jake Scott, a clinical associate professor at Stanford University School of Medicine, said in a post on X that "the claim that mRNA vaccine technology poses more risk than benefits is simply false."
"What poses risk is abandoning the most adaptable, scalable vaccine platform we've ever had," he wrote. "Halting future development undermines pandemic preparedness at a time when we can least afford it."

ACA premiums set to spike
The proposed rates are preliminary and could change before being finalized in late summer. The analysis includes proposed rate changes from 312 insurers in all 50 states and DC. It's the largest rate change insurers have requested since 2018, the last time that policy uncertainty contributed to sharp premium increases. On average, ACA marketplace insurers are raising premiums by about 20 percent in 2026, KFF found. Insurers said they wanted higher premiums to cover rising health care costs, like hospitalizations and physician care, as well as prescription drug costs. Tariffs on imported goods could play a role in rising medical costs, but insurers said there was a lot of uncertainty around implementation, and not many insurers were citing tariffs as a reason for higher rates. But they are adding in higher increases due to changes being made by the Trump administration and Republicans in Congress. For instance, the majority of insurers said they are taking into account the potential expiration of enhanced premium tax credits. Those subsidies, put in place during the COVID-19 pandemic, are set to expire at the end of the year, and there are few signs that Republicans are interested in tackling the issue at all. If Congress takes no action, premiums for subsidized enrollees are projected to increase by over 75 percent starting in January 2026, according to KFF. But some states are pushing back. Arkansas Gov. Sarah Huckabee Sanders (R) on Wednesday called on the state's insurance commissioner to disapprove the proposed increases from Centene and Blue Cross Blue Shield. The companies filed increases of up to 54 percent and 25.5 percent, respectively, she said. 'Arkansas' Insurance Commissioner is required to disapprove of proposed rate increases if they are excessive or discriminatory, and these are both,' Huckabee Sanders said in a statement. 'I'm calling on my Commissioner to follow the law, reject these insane rate increases, and protect Arkansans.'

Huge cuts to mRNA research spark fears about future pandemics
Health Secretary Robert F. Kennedy Jr.'s decision this week to cancel hundreds of millions of dollars in mRNA vaccine funding will leave the United States unprepared for the next pandemic and other public health emergencies, public health experts warned. 'I've tried to be objective & non-alarmist in response to current HHS actions—but quite frankly this move is going to cost lives,' President Trump's former surgeon general Jerome Adams said in a post to X. 'mRNA technology has uses that go far beyond vaccines… and the vaccine they helped develop in record time is credited with saving millions.' The first COVID-19 mRNA vaccines from Pfizer and Moderna hit the market in 2021, just a year after the virus first appeared. Vaccines typically take years to develop, but the mRNA shots were developed in record time due to a massive influx of funding from the first Trump administration, dubbed Operation Warp Speed. The COVID shots proved safe and effective, and helped bring about an end to the pandemic. Experts say mRNA technology has the potential to revolutionize treatments for evolving pathogens, especially bird flu, because the platform can be easily modified. On Tuesday, Kennedy cancelled $500 million worth of contracts related to mRNA vaccine research being funded by the Biomedical Advanced Research and Development Authority. Instead, he said the agency will focus on platforms with 'stronger safety records.' Public health experts point out that reviews of the hundreds of millions, if not billions, of doses of mRNA shots administered worldwide have found very few adverse events. 'It's pretty clear that the administration, or at least the secretary, has a political vendetta not just against vaccines but against mRNA in general,' said Jeff Coller, a professor of RNA biology and therapeutics at Johns Hopkins University. Coller said the move will put the U.S. behind other nations in biomedical research and sends a 'clear message' to scientists and the industry that it is not wise to invest in mRNA technology because if they do, they will likely not receive funding or approval from the federal government. Jennifer Nuzzo, a professor of epidemiology and director of the Pandemic Center at Brown University School of Public Health, told The Hill that the cancellation is a threat to national security, as it opens the U.S. to future public health emergencies caused by biological warfare. 'One of the ways that we deter that from happening is to say the United States is absolutely committed to preparedness,' Nuzzo said. 'When we take them off the table and leave nothing in their place, we basically signal to our adversaries that we are no longer interested in defending ourselves.' In the long run, Nuzzo said, winding down research efforts on mRNA vaccine platforms will stifle medical innovation coming out of the U.S., including new treatments for diseases like cancer. 'It's troubling on a number of fronts,' she said. MRNA vaccines work by sending instructions to cells to make a specific type of protein found on the outer membrane of a virus. The body's immune system is then able to recognize that protein as something foreign and will create antibodies to fight it. That same general approach could be used to help potentially vaccinate someone against a particular cancer, according to Nuzzo. 'Cancers have a genetic signature,' she said. 'We don't know what's going to happen but there are some preliminary studies that suggest it could be a very promising way to treat cancers.' None of the canceled contracts directly deal with cancer research, but the move will likely cause a chilling effect among researchers that ultimately impacts cancer-related work, said Michael Osterholm, founding director of the Center for Infectious Disease Research and Policy and member of the Vaccine Integrity Project. 'I think you're going to see anyone who is willing to invest in mRNA technology, pulling back, if not completely, getting out of this business,' he said. 'This is terribly unfortunate, given that we have a number of other infectious diseases for which this vaccine platform was being explored in terms of taking on other infectious diseases and including some cancer vaccines.' Kennedy is deeply skeptical of vaccines in general, and mRNA vaccines in particular. In 2021, he falsely said the mRNA COVID-19 vaccine was the 'deadliest vaccine ever made.' Kennedy has also been facing pressure from fellow anti-vaccine activists for not doing enough to keep mRNA vaccines off the market. He was criticized earlier this year when the Food and Drug Administration approved Moderna's updated COVID-19 vaccine, even though the agency limited its use in children. In a video posted to X on Tuesday, Kennedy falsely claimed mRNA shots don't protect against respiratory viruses and don't work if a virus mutates. 'One mutation and the vaccine becomes ineffective,' Kennedy said. Following the announcement, public health experts urged Congress to restore funding towards mRNA vaccine research, with some calling it an 'assault' on federal vaccine policy. 'The HHS Secretary continues a mindless assault on sound federal vaccine policy,' said Robert Steinbrook, director of the Public Citizen Health Reseach Group. 'The mRNA vaccine platform was essential to rapid vaccine development and deployment during the COVIVD-19 pandemic and remains essential to preparing for future public health emergencies.' But the full extent of Kennedy's move isn't known. A Moderna spokesperson told The Hill that they were not aware of any new award cancellations since their contract to help develop an H5N1 bird flu vaccine was canceled in May. Gritstone Bio, another company on the HHS list of cancelled contracts, ceased operations earlier this year after the company filed for bankruptcy in 2024. A spokesperson for Tiba Bio said HHS's decision to terminate their BARDA contract 'comes as a surprise' since its contract was for a therapeutic, not a vaccine, and it does not use mRNA technology. Instead, it uses a method called RNA interference, which the FDA approved to treat some diseases in 2018.

American doctors describe dire conditions at a Khan Younis hospital in Gaza
A pair of American volunteer doctors described to NBC News a barely coping hospital in Gaza, with bodies spread across the blood-smeared floors as medical staff struggled to treat hundreds of people who had been injured as they tried to access humanitarian aid. 'We have children who are dead on the floor and we are unable to move these patients just due to the sheer volume that we received,' Ahmed Farhat, an emergency physician from California, told NBC News in a video message Tuesday, talking about the situation at the Nasser Medical Complex in the city of Khan Younis. 'We have patients who are intubated on the floor with no sedation. We have patients who have chest tubes on the floor, patients who are bleeding out,' added Farhat, who is just under two weeks into a medical mission run by the Michigan-based Rahma Worldwide, a charity founded in 2014 that operates emergency response and humanitarian relief programs across the Middle East and Africa. His comments echo those of other doctors working in Gaza who in recent interviews with NBC News have lamented the lack of food and medicine being allowed into the enclave, amid international outrage over widespread starvation and deaths from malnutrition. Others have described aid distribution points as death traps, as a growing number of people have been killed or injured while seeking desperately needed food. Three short videos taken by Farhat in the Nasser Medical Complex on Tuesday showed dozens of people waiting for treatment on the hospital's floors. Some had tubes inserted to help them breathe, others were motionless. Citing hospital administration data, Farhat said in a text message on Wednesday that the Nasser Complex received 453 patients within a number of hours on Tuesday, and 48 of them had died. He added that his patients told him they had come under fire by Israeli forces while trying to collect aid from two sites run by the Gaza Humanitarian Foundation, the U.S. and Israel-backed organization that has been mired in controversy since replacing most United Nations-run relief operations in Gaza in May. In a statement to NBC News on Wednesday, the GHF, which operates four militarized food aid distribution sites across the enclave in areas where the Israeli military is active, said aid convoys belonging to the United Nations and other organizations in the past often passed near their locations and were regularly looted by large crowds. However, it said there were 'no incidents at or near' their sites on Tuesday. A spokesperson for the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) could not confirm whether its aid convoys had been looted near GHF sites. NBC News has reached out to the Israeli military for comment about the casualties at Nasser Hospital. Farhat said other patients had told him they had been fired upon in another incident near Gaza's southernmost city of Rafah while seeking aid from a United Nations aid convoy that was passing through. An OCHA spokesperson did not have any details about the specific event, but said such incidents are not uncommon. Separately, the Health Ministry in Hamas-run Gaza said Wednesday that 87 people had been killed and 570 injured in a series of incidents across the enclave on Tuesday. Travis Melin, an anesthesiologist from Oregon who also volunteers at the Nasser Hospital, said the number of patients on Tuesday had been 'huge.' In a text message Wednesday, he added that he had seen the highest number of casualties at the hospital during his monthlong tenure there. 'We're still doing emergency surgery on people who should have gone to the OR yesterday,' he said. The 'worst-case scenario of famine' is unfolding in the Gaza Strip under Israel's assault, the world's leading body on hunger said last week. Meanwhile, most of its residents have been driven from their homes and more than 61,000 killed, including thousands of children, according to local health officials. Israel launched its offensive in Gaza following the Hamas-led Oct. 7, 2023, terror attacks in which some 1,200 people were killed and around 250 taken hostage. Nearly 1,400 people have been killed and more than 4,000 injured while seeking food, the United Nations' OCHA said in an update Tuesday. 'At least 859 people have been killed around GHF sites since the beginning of GHF's operations,' it added.
