The shingles vaccine is intended to prevent shingles, a painful rash caused by the reactivation of the varicella-zoster virus, also known as herpes zoster — but a new study suggests that it could have major secondary benefits.

Researchers at Case Western Reserve University have identified a potential link between the shingles vaccine and a reduced risk of developing vascular dementia.

The vaccine has also been associated with a significant decreased risk of cardiovascular events and death in people 50 and older.

Experts presented the findings last week at the Georgia World Congress Center in Atlanta, the site of IDWEEK 2025, a joint annual meeting of the leading infectious disease professional societies in the U.S.

The study authors examined health records from 174,000 adults in the U.S. They followed participants who received the vaccination over a span of three months up to seven years.

Participants who received the shingles vaccine had about half the risk of developing vascular dementia.

They also had a 25% lower risk of heart attack or stroke, a 27% lower risk of blood clots and a 21% lower risk of death, according to a news release from the Infectious Diseases Society of America.

“Our study findings show that the shingles vaccine may help lower those risks, especially in people already at higher risk for heart attack or stroke,” presenting author Ali Dehghani, a doctor of internal medicine at Case Western Reserve University’s School of Medicine in Cleveland, Ohio, said in the IDSA report.

Shingles is a red, blistery, painful rash caused by the reactivation of the virus that causes chicken pox. The latent varicella zoster virus lies dormant in the body after a person has chicken pox. It can become activated in later years, causing shingles, health experts told Fox News Digital.

The condition can lead to cardiovascular and neurologic complications, previous studies have shown.

Shingles affects one out of three Americans, and more than 99% of those born before 1980 have had chicken pox, according to the Centers for Disease Control and Prevention.

“Shingles is more than just a rash — it can raise the risk of serious problems for the heart and brain,” Dehghani said in the news release.

These latest findings build on past studies that indicate the vaccine may help protect individuals against shingles and related complications, according to infectious disease experts.

“This very interesting study … supported prior evidence that the shingles vaccine may offer several benefits for general health, including against the development of dementia, in addition to preventing the very painful and common illness know as shingles,” Dr. Aaron Glatt, a spokesperson for the ISDA and a board-certified infectious disease physician at Mount Sinai South Nassau in Oceanside, New York, told Fox News Digital.

While more studies are needed, a doctor said, “It is very comforting to know that the shingles vaccine is certainly associated with overall significant health benefits beyond its intended purpose.” (iStock)

Although these findings are “very exciting and potentially clinically important,” Glatt — who was not involved in the study — noted that it’s not yet proven that these benefits are due to the shingles vaccine.

While more studies are needed, Glatt said, “It is very comforting to know that the shingles vaccine is certainly associated with overall significant health benefits beyond its intended purpose.”

The CDC recommends two doses of recombinant zoster vaccine (RZV) to prevent shingles and related complications in adults aged 50 years and older, as well as for adults aged 19 and older who are or will be immunodeficient or immunosuppressed.

Woman’s painful reaction to wine leads to life-changing cancer discovery

One woman’s uncomfortable reaction to alcohol led to a grave discovery.

Hollie Thursby, 28, a mother of two from the U.K., told Kennedy News and Media that after giving birth to her second son, Jack, she began experiencing unusual symptoms.

At a checkup for her son, who was a couple of months old, Thursby mentioned that she was experiencing “unbearably itchy skin,” which is known to be a post-partum symptom. The doctor suggested it was due to changing hormones.

Thursby added that she occasionally drank a couple glasses of wine. Although she kept the drinking to a minimum, she described having “a lot of pain” down the side of her neck.

“Really quite painful and uncomfortable,” she said, according to the report.

The mother also reported feeling extremely exhausted, which she assumed was due to caring for her children throughout the day.

“I also felt like when I got to bed that someone was sitting on my chest,” she shared.

In July 2025, Thursby discovered a lump on the side of her neck that she described as “really quite big,” but wasn’t painful, Kennedy News and Media reported.

“It was hard, it didn’t move, but it was there,” she said. “When I turned my neck to the side, you could see it.”

Thursby reportedly began chemotherapy for Stage 2 Hodgkins lymphoma. (Kennedy News and Media)

Thursby’s symptoms turned out to be a form of blood cancer — Stage 2 Hodgkins lymphoma, which means it is in two or more lymph nodes, according to Cancer Research U.K.

Common symptoms include swelling of the lymph nodes, heavy sweating, weight loss, itching, persistent cough or shortness of breath, high temperatures, and pain in the stomach or lymph nodes after drinking alcohol.

“Pain when you drink alcohol is actually a known side effect of Hodgkin lymphoma,” she said, per the report. “It’s something about the acidity in the wine and not when you drink other alcohol.”

While alcohol-related pain in Hodgkins lymphoma patients has been “an accepted scientific consensus” since the 1950s, cases are rare, Healthline confirmed.

Thursby reportedly began chemotherapy in November, noting that the hardest part is not being able to care for her kids after losing her own mother to a blood disorder called myelodysplasia.

“I grew up without a mum, and it was horrendous. I can’t do that to the boys,” she told Kennedy News and Media. “We’re all devastated, but we all know now, and we’ve got a treatment plan, which is what we need.”

Red light therapy could boost brain health in certain groups, new research suggests

NEWYou can now listen to Fox News articles!

Red light therapy has been shown to reduce brain inflammation, protecting people who experience head trauma from long-term health consequences, a University of Utah study has shown.

Brain damage from repeated impact over the years is known to cause cognitive symptoms, ranging from memory issues to full-blown dementia, particularly affecting soldiers and athletes.

Chronic traumatic encephalopathy (CTE) is a progressive, degenerative brain disease linked to repeated head impacts rather than a single injury, according to Mayo Clinic.

More than 100 former NFL football players have been posthumously diagnosed with CTE, according to the new study, which was published in the Journal of Neurotrauma.

Other research has shown that military personnel in active combat suffer from similar issues, as do first responders and veterans.

The treatment was administered three times a week for 20 minutes using specialized headsets and intranasal devices designed to penetrate the skull. (iStock)

In the new study, the researchers recruited 26 current football players to understand more about the impact of red-light therapy on brain injuries.

The participants received either red light therapy delivered by a light-emitting headset and a device that clips into the nose, or a placebo treatment with an identical device that doesn’t produce light. Players self-administered the therapy three times a week, 20 minutes each time, for 16 weeks.

“My first reaction was, ‘There’s no way this can be real,’” said first author Hannah Lindsey, Ph.D., in the university press release. “That’s how striking it was.”

Specific wavelengths of light are believed to enter the brain and reduce molecules that trigger inflammation, potentially halting the path toward dementia and other cognitive conditions. (iStock)

Players using the placebo treatment experienced increased brain inflammation over the course of the season. Magnetic resonance imaging (MRI) scans taken at the end of the season showed significantly more signs of inflammation than at the beginning of the season, the study found.

For players who used red-light therapy during the season, their brain inflammation didn’t increase at all.

“When we first started this project, I was extremely skeptical,” said Elisabeth Wilde, Ph.D., the senior author on the study. “But we’ve seen consistent results across multiple of our studies, so it’s starting to be quite compelling.”

Study limitations

The study was conducted using a small sample size, which led to different levels of inflammation in the treatment and control groups, the researchers acknowledged.

Future large randomized clinical trials will be “crucial to back up the results” in larger populations, they noted.

“We’ve been trying to figure out how to make sports safer, so that our kids, friends and family can participate in sports safely for the long term while they’re involved in activities that give them happiness and joy,” Carrie Esopenko, Ph.D., second author of the study, said in the release.

“And this really feels like part of the hope for protecting the brain that we’ve been searching for.”

Deadly cancer risk spikes with certain level of alcohol consumption, study finds

NEWYou can now listen to Fox News articles!

Drinking heavily and consistently over an adult’s lifetime could lead to a higher risk of colorectal cancer, according to a study published in the journal Cancer by the American Cancer Society (ACS).

The study analyzed 20 years of data from more than 88,000 U.S. adults to determine how long-term drinking impacted the risk of developing colorectal cancer (CRC) or precancerous colorectal adenomas (polyps).

The participants reported their average weekly intake of beer, wine and liquor intake during four age periods 18 to 24, 25 to 39, 40 to 54,  and 55 and older.

“Heavy drinkers” were identified as having more than 14 drinks per week and “moderate drinkers” had between seven and 14 drinks per week.

The observational research revealed that consistent heavy drinking over adulthood was linked to a higher risk of colorectal cancer, especially rectal cancer.

Researchers found a major association between colorectal cancer diagnosis and heavy lifetime drinking. (iStock)

Heavy lifetime drinking was associated with a 25% higher overall CRC risk and nearly double the risk of rectal cancer. Moderate lifetime drinking had a lower overall CRC risk.

Compared to light drinkers, the consistently heavy drinkers had about a 91% higher risk of CRC.

For colorectal adenomas (precancerous polyps), higher current lifetime drinking did not show a strong pattern, although former drinkers showed a significantly lower risk of non-advanced adenoma compared to current light drinkers.

Out of the 88,092 participants, 1,679 were diagnosed with colorectal cancer.

The authors noted that the research was limited, as it was observational and not based on a clinical trial. It also hinged on self-reported alcohol use.

The findings suggest that consistently heavy alcohol intake and higher average lifetime consumption “may increase CRC risk, whereas cessation may lower adenoma risk,” the researchers stated. Associations “may differ by tumor site,” they added.

The link between drinking alcohol and cancer is not a new discovery, according to health experts.

In a recent episode of the podcast “The Dr. Mark Hyman Show,” Dr. Mark Hyman, chief medical officer of Function Health in California, detailed how even moderate drinking can impact “nearly every organ system in the body,” due to metabolic stress, inflammation, impaired detoxification and its effect on hormones.
