RFK Jr's FDA limits use of Covid vaccine
The vaccine will now only be available to high-risk individuals and will not be administered to those who may need it to protect others.
Kennedy's FDA approved the use of the Novavax Covid-19 vaccine, but with strict conditions. It will only be made available to older people and those over the age of 12 with at least one medical condition that leaves them at high risk from Covid, The New York Times reported.
Centers for Disease Control and Prevention advisers have been discussing whether to recommend the vaccine only for those most at risk. The new restrictions mean that healthy people over the age of 65 won't be able to get the Novavax vaccine, even if they have an immunocompromised friend or family member.
Critics have slammed the restrictions for being in line with Kennedy's vaccine skepticism. The secretary has ordered an investigation into the debunked claim that vaccines cause autism.
The Novavax vaccine was previously only allowed to be used in emergencies. Meanwhile, the FDA gave full approval to vaccines by Pfizer-BioNTech and Moderna in 2022 under the Biden administration. Both companies are producing updated versions of their vaccines for the fall.
Former CDC adviser and Massachusetts General Hospital infectious disease physician Dr Camille Kotton told The Times that the new restrictions were 'incredibly disappointing.'
'I don't know why they would make this restriction; I don't know of any indication to make this change,' she added. She noted that many people are still sent to hospital and dying because of Covid-19. She called it 'a dark day in American medicine.'
The vaccine's approval requires the company to finish studies into whether it is connected to several heart conditions. However, some of the necessary research can be done with existing data.
However, The Times reported that one of the new studies would force the company to follow thousands of people between the ages of 50 and 65, a study that may cost tens of millions of dollars.
Dr. Ofer Levy of Boston Children's Hospital, where he directs the precision vaccine program, is a vaccine adviser to the FDA.
'We've got to make sure the vaccine safety is crystal clear to engender public confidence,' Levy noted. 'On the other hand, where's that line where you put in too much regulation, it starts to become so challenging that the economics of even making a vaccine are called into question?'
'I don't pretend to know the answer,' Levy added.
Dr. Paul Offit is a vaccine expert at the Children's Hospital of Philadelphia.
'I think the goal of Robert F. Kennedy Jr. is to make vaccines less available, more expensive, and more feared,' he told the paper. 'His goal is to tear away at the vaccine infrastructure, because he believes that vaccines are not beneficial and are only harmful.'

Why cancer patients may have to avoid popular sugar substitute
New research from the University of Pittsburgh and UPMC Hillman Cancer Center suggests that sucralose, a popular sugar substitute, may interfere with the effectiveness of certain cancer treatments. Patients with melanoma and non-small cell lung cancer who consumed high levels of sucralose responded worse to immunotherapy and had poorer survival rates. The study, primarily conducted on mice, found that sucralose disrupts gut bacteria, leading to a depletion of the amino acid arginine, which is essential for T-cell function and effective immunotherapy. Researchers discovered that supplementing with arginine counteracted the negative effects of sucralose on immunotherapy treatments in mice. Future plans include pursuing clinical trials to determine if arginine supplementation can mitigate sucralose's effects in humans and investigating the impact of other artificial sweeteners on the immune system and cancer treatments.

Warning issued for common artificial sweetener that can interfere with cancer treatments
A popular sugar substitute may interfere with certain cancer treatments, according to new research. The University of Pittsburgh and UPMC Hillman Cancer Center have released new research suggesting that using sucralose — a popular sugar replacement used by those trying to lose weight or manage their blood sugar levels — may make it harder to the body to respond to certain cancer treatments. According to the research, patients with melanoma and non-small cell lung cancer who consumed high levels of sucralose responded worse to immunotherapy and had worse survival rates than individuals whose diets had low levels of the artificial sweetener. The research also revealed a potential pathway for counteracting the potential negative effects of sucralose. The researchers found supplements that boost the levels of amino acid arginine actually counteracted the negative effects of the sweetener on immunotherapy treatments in mice. That approach could be pursed in further clinical trials to see if it can be used in humans. Doctor Abby Overacre, assistant professor in the Department of Immunology at the University of Pittsbugh and UPMC Hillman said in a statement that finding ways around forcing dietary changes is a worthwhile course of action, especially for cancer patients who are already dealing with the burden of the disease. 'It's easy to say, 'Stop drinking diet soda,' but when patients are being treated for cancer, they are already dealing with enough, so asking them to drastically alter their diet may not be realistic,' she said. 'We need to meet patients where they are. That's why it's so exciting that arginine supplementation could be a simple approach to counteract the negative effects of sucralose on immunotherapy.' The study, which used testing on mice, found the negative effects were potentially caused by disruption to gut bacteria by the artificial sweetener. It found that sucralose caused a shift in the composition of the gut bacteria in mice which allowed for an increase in bacteria that degrade arginine. The increased arginine resulted in reduced levels of the amino acid in blood, tumor fluid, and stool. 'When arginine levels were depleted due to sucralose-driven shifts in the microbiome, T cells couldn't function properly,' Overacre said. 'As a result, immunotherapy wasn't as effective in mice that were fed sucralose.' Diwakar Davar, associate professor of medicine at the University of Pittsburgh and a medical oncologist and hematologist at UPMC Hillman, was a collaborator on the study and noted that the negative effects of sucralose was consistent across a range of treatments for a variety of cancer types and stages. He said that prebiotic supplements could theoretically be developed specifically for cancer patients with high levels of sucralose in their blood to help mitigate the negative effects. The researchers hope to pursue a clinical trial to determine whether or not boosting arginine through supplements will counteract the effects of the sucralose. They also plan to expand their research to look at the effects of other artificial sweeteners — such as aspartame, saccharin, xylitol, and stevia — on the immune system and on cancer treatments.

Trump administration blocks funding for CDC health programs, WSJ reports
Aug 1 (Reuters) - U.S. President Donald Trump's administration is blocking funding for a swath of public-health programs run by the Centers for Disease Control and Prevention, the Wall Street Journal reported on Friday, citing unnamed sources. These include youth violence prevention programs, research on preventing gun injuries and deaths and efforts targeting diabetes, chronic kidney disease and tobacco use, according to the report. The money withheld could not be determined, but it could be as high as $200 million, the WSJ reported, citing a person familiar with the matter. The CDC did not immediately respond to a Reuters request for comment. The White House has previously stated its intention to reduce U.S. health spending by more than a quarter next year, with the National Institutes of Health and the Centers for Disease Control and Prevention facing the brunt of billions of dollars in cuts. Earlier this week, Susan Monarez was confirmed as CDC director to lead a downsized agency as the White House moves to slash its budget by nearly $3.6 billion, reducing it to about $4 billion. The cuts follow a layoff plan enacted by U.S. Health Secretary Robert F. Kennedy Jr. that eliminated 2,400 positions in CDC, though roughly 700 of those workers have since been rehired.
