RFK Jr. Offers Qualified Support for Measles Vaccination
In a rare sit-down interview with CBS News, Robert F. Kennedy Jr., the nation’s health secretary, recommended the measles vaccine and said he was “not familiar” with sweeping cuts to state and local public health programs.
The conversation was taped shortly after his visit to West Texas, where he attended the funeral of an 8-year-old girl who died after contracting measles. A raging outbreak there has sickened more than 500 people and killed two young children.
In clips of the discussion released Wednesday, Mr. Kennedy offered one of his strongest endorsements yet of the measles vaccine. “People should get the measles vaccine, but the government should not be mandating those,” he said.
A few moments later, however, he raised safety concerns about the shot, as he has previously: “We don’t know the risks of many of these products because they’re not safety tested,” he said.
For months, Mr. Kennedy has faced intense criticism for his handling of the West Texas outbreak from medical experts who believe that his failure to offer a full-throated endorsement of immunization has hampered efforts to contain the virus.
Moreover, he has promoted unproven treatments for measles, like cod liver oil. Doctors in Texas believe its use is tied to signs of liver toxicity in some children arriving in local hospitals.
Throughout the outbreak, Mr. Kennedy has often paired support for vaccines with discussions of safety concerns about the shots, along with “miraculous” alternative treatments.
Over the weekend, he posted on social media that the measles, mumps and rubella vaccine was “the most effective way” to prevent the spread of measles — a statement met with relief from infectious disease experts and with fury from his vaccine-hesitant base.
That night, he posted again, this time applauding “two extraordinary healers” who he claimed had effectively treated roughly 300 measles-stricken children with budesonide, a steroid, and clarithromycin, an antibiotic.
Scientists say there are no cures for a measles infection, and that claiming otherwise undermines the importance of a vaccination.
Later in the CBS interview, Mr. Kennedy was pressed on the administration’s recent move to halt more than $12 billion in federal grants to state programs that address infectious disease, mental health and childhood vaccinations, among other efforts.
(A judge has temporarily blocked the cuts after a coalition of states sued the Trump administration.)
Mr. Kennedy said he wasn’t familiar with the interruptions, then asserted that they were “mainly D.E.I. cuts,” referring to diversity, equity and inclusion programs that have been targeted by the Trump administration.
Dr. Jonathan LaPook, CBS’s medical correspondent, asked about specific research cuts at universities, including a $750,000 grant to researchers at the University of Michigan to study adolescent diabetes.
“I didn’t know that, and that’s something that we’ll look at,” Mr. Kennedy said. “There’s a number of studies that were cut that came to our attention and that did not deserve to be cut, and we reinstated them.”

Taking a GLP-1 medication for weight loss may improve male fertility, according to experts.
Research presented this week at ENDO 2026, the Endocrine Society’s annual meeting in Chicago, explored how obesity is strongly linked to fertility problems in men.
Excess weight can contribute to dysregulation of the hypothalamic-pituitary-gonadal (HPG) axis — the hormone system that regulates testosterone production — and functional hypogonadism, a condition in which testosterone levels are abnormally low because of disrupted hormone signaling. These changes can also impair semen quality.
WEIGHT-LOSS MEDICATIONS COULD IMPACT SEXUAL HEALTH IN UNEXPECTED WAYS
The researchers evaluated how GLP-1 weight-loss drugs impact reproductive hormones and metabolic outcomes, analyzing data of men between the ages of 18 and 65 who were taking one of the medications, according to a press release.
The systematic review of five randomized controlled trials focused on measuring testosterone, brain hormones involved in testosterone and sperm production, and a protein that carries sex hormones in the blood. Semen quality, weight and BMI, cholesterol and blood sugar were also measured.

The results suggested that GLP-1 medications do not suppress male hormones. Men with obesity and low testosterone linked to obesity may experience improved testosterone, sperm quality and metabolic health, especially during weight loss.

In one four-week study, dulaglutide showed no significant changes in reproductive hormones or sexual function.
In a separate 16-week trial, liraglutide improved hormones in obese men with functional hypogonadism, meaning low testosterone was likely related to obesity. The review found that liraglutide was better for health outcomes than hormone replacement therapy.

Another liraglutide study reported improved sperm concentration and count.
The study authors concluded that GLP-1s “do not appear to acutely suppress the male HPG axis and may improve reproductive hormones and semen parameters in obese hypogonadal men, largely within the context of weight loss.” (iStock)
A 24-week trial of semaglutide, known commercially as Ozempic and Wegovy, saw improvement in sperm shape and bad cholesterol, while preserving total testosterone.
As only five trials were included, the small evidence base suggests more research is necessary to prove further association.

In an abstract of the research, the authors summed up that GLP-1s “do not appear to acutely suppress the male HPG axis and may improve reproductive hormones and semen parameters in obese hypogonadal men, largely within the context of weight loss.”
“However, evidence remains limited and heterogeneous, underscoring the need for larger RCTs explicitly powered to assess male reproductive outcomes,” they wrote.
“This provides early evidence that GLP-1 medications taken by obese men with hypogonadism/low testosterone (low T) improves testosterone levels,” one doctor said. (iStock)
Dr. Anthony Puopolo, men’s health expert and lead medical provider for RexMD, reflected on these findings in an interview with Fox News Digital.
“This provides early evidence that GLP-1 medications taken by obese men with hypogonadism/low testosterone (low T) improves testosterone levels,” he said.

While more research is necessary, Pupolo, who was not involved in the study, shared his optimism about how GLP-1s can play a role in improving male fertility.
“If this finding continues to gain evidence, GLP-1s might be a better option for low T than testosterone replacement therapy (TRT) in obese men – as GLP-1 medications preserve fertility, whereas TRT tends to be harmful to male reproductive/sperm function,” he added.
