With whooping cough cases on the rise, do you need a booster vaccine?
As whooping cough cases are surging globally, some may wonder if it’s necessary to get a booster.
Cases of the childhood respiratory disease also known as pertussis are surging internationally and in parts of the U.S., according to a recent report.
Bordetella pertussis is a type of bacteria that causes a very contagious respiratory infection that spreads from person to person through small respiratory droplets, per the CDC.
NEW YORK HEALTH OFFICIALS WARN OF WHOOPING COUGH OUTBREAK AMONG CHILDREN
“Reports indicate that whooping cough outbreaks are surging across Europe, Asia and parts of the United States, including Northern California, marking the largest uptick since 2012, with cases rising sharply since December,” Maggie Rae, president of the Royal Society of Medicine’s epidemiological and public health section in London, told Fox News Digital.

Prevalence of cases
In the U.K., there were an estimated 555 cases in January of this year and 913 cases in February — compared to 858 cases for all of 2023, according to the UK Health Security Agency.
Cases in China totaled more than 15,000 this January. That’s 15 times higher than the same time period last year, reports stated.

“Concerns are mounting in Europe, especially in the Netherlands, where 1,800 cases were reported in the first two weeks of April, leading to four deaths, with declining childhood vaccination rates cited as a possible cause by public health officials,” Rae said.
“This is a very important public health issue, and I would urge those members of the public who require a vaccine for pertussis to take this up.”
Whooping cough is mostly controlled in the United States, although “breakthrough cases” can occur in people who are fully vaccinated.

Clusters of cases in certain parts of the U.S. are expected for this time of year, according to the Centers for Disease Control and Prevention (CDC).
There have been small “clusters” of cases of whooping cough in the U.S., extending from San Francisco to New York City.
CDC RECOMMENDS ADDITIONAL COVID VACCINE FOR ADULTS 65 AND OVER
A Catholic high school in San Francisco, California, has reported more than 12 cases since January, according to local reports.
The New York City Department of Health and Mental Hygiene estimated 244 cases from Oct. 1, 2023, to Jan. 31, 2024.
That’s a 200% increase compared to the same time period in the prior year, a recent health advisory stated.
“This is a very important public health issue.”
Most unvaccinated cases involved infants, while most vaccinated individuals were school-aged children.
A majority of adults had an unknown vaccination history, the advisory noted.
The U.S. typically has approximately 20,000 cases of pertussis per year. Yet as people donned masks and practiced physical distancing during the pandemic, annual cases dropped to 6,124 in 2020 and 2,116 in 2021, according to the CDC.
Symptoms and risk factors
Clusters of cases often occur where there are large groups of young people, such as child care centers and schools.
“The symptoms of pertussis are initially like a cold, with a runny nose, and progress to a cough,” Jennifer Duchon, M.D., hospital epidemiologist and director of antimicrobial stewardship at Mount Sinai Kravis Children’s Hospital in New York, told Fox News Digital.
Patients tend to develop a cough that can become severe — sometimes to the point of vomiting, Duchon said.

“The characteristic ‘whooping’ sound is a gasp that is made when trying to breathe after a long episode of coughing,” she added.
The cough can linger for weeks after a person catches pertussis.
When outbreaks occur, babies are at a high risk of getting sick and dying from the infection, health officials warn.

“Pertussis is most severe in infants 6 months of age or less, especially in infants who were born preterm or are not immunized,” Duchon said.
“Young infants can have a severe cough that impairs their ability to breathe, and can lead to episodes where they vomit, struggle to breathe or even cease breathing after bouts of coughing.”

Babies often won’t make that whooping sound, so a warning sign is when their face turns blue as they struggle to breathe, the CDC noted.
The infection can progress to bacterial pneumonia or a condition called pulmonary hypertension, in which heart function is affected by the disease, Duchon warned.
Treatment and prevention
Health care providers typically test for the disease with a nasal swab.
“If pertussis is caught early, patients can take an antibiotic called azithromycin, but this only helps make the disease less severe and does not cure the disease,” Duchon noted.

“If someone is exposed to pertussis and is at risk for severe disease or had a lot of contact with the ill person, doctors will sometimes recommend a short course of an antibiotic to act as a ‘prophylaxis’ against the disease.”
Currently, there are two kinds of vaccines for whooping cough available in the U.S., according to the CDC.
“The best way to prevent the disease is to make sure that all family members and health care workers are up-to-date on their vaccinations — not only for pertussis, but also other vaccine-preventable diseases,” Duchon told Fox News Digital.
“Children should get their primary series of vaccines at 2 months, 4 months and 6 months, and then at 15 months through 18 months, and at 4 years through 6 years,” a doctor advised. (iStock)
The DTaP vaccine protects against diphtheria, tetanus and pertussis.
The Tdap vaccine protects against tetanus, diphtheria and pertussis.
The DTaP vaccine is for babies, while the Tdap “booster” vaccine is for pre-teens, teenagers and adults, per the CDC.
“Before vaccination became available, the disease used to be a major cause of mortality in young children,” Duchon noted.
Specific vaccine recommendations
Due to the high risk to babies, the CDC recommends that pregnant women receive the Tdap vaccine during the 27th and 36th week of pregnancy, regardless of their prior vaccination status.
This prevents 78% of cases in infants younger than 2 months old and decreases hospitalization by 90% for infants younger than 2 months old who are infected with pertussis, according to the CDC.
“Everyone in close contact with a very young infant should be vaccinated against pertussis.”
It is recommended that babies get immunized with the DTaP vaccine series, which provides immunity for three separate infectious diseases — diphtheria, tetanus and pertussis.
“Children should get their primary series of vaccines at 2 months, 4 months and 6 months, and then at 15 months through 18 months, and at 4 years through 6 years,” Duchon advised.

Adolescents should receive the Tdap vaccine at 11 to 12 years old to boost their immunity, the CDC recommends.
In children who receive the full series, 98% have full protection against the infection within a year after the last dose, but the response decreases to 71% after five years, the agency states.

As pertussis immunity wanes from the original vaccination series in childhood, adults should get regular boosters, Monica Gandhi, M.D., professor of medicine and an infectious disease specialist at UCSF/ San Francisco General Hospital, told Fox News Digital.
“Although the exact frequency of the need for booster vaccination has not been precisely worked out, we recommend a tetanus vaccine every 10 years,” she said.

As the pertussis vaccine comes formulated with tetanus immunization in the form of the Tdap vaccine, many practitioners recommend a pertussis vaccine every 10 years when the booster for tetanus is provided, according to Gandhi.
Other providers may only recommend routine pertussis boosters in certain circumstances, such as for pregnant women or adults who have never been vaccinated, Duchon added.
“Everyone in close contact with a very young infant should be vaccinated against pertussis,” she said.
“We call this strategy ‘cocooning,’ where those around the baby form a protective wall against the disease.”

Big moves are continuing in the weight loss landscape in the new year following breakthrough research of GLP-1 medications and other methods.
Weight-loss experts spoke with Fox News Digital about their predictions for the most major changes to come in 2026.
No. 1: Shift to whole-body treatment
Dr. Peter Balazs, a hormone and weight loss specialist in New York and New Jersey, shared that the most important shift is likely to label GLP-1 drugs as “multi-system metabolic modulators” rather than “simple weight loss drugs.”

“The treatment goal is no longer just BMI reduction, but total cardiometabolic risk mitigation, with effects now documented across the liver, heart, kidneys and vasculature,” he said.
“We are seeing a significant reduction in major adverse cardiovascular events … and progression of renal disease,” he went on.
The focus of GLP-1 drugs will widen beyond weight loss and diabetes, according to experts’ predictions. (iStock)
Philip Rabito, M.D., a specialist in endocrinology, weight loss and wellness in New York City, also shared that “exciting” advancements lie ahead for weight-loss drugs, including GLP-1s and GIPs.

“These next‑generation agents, along with novel combinations that include glucagon and amylin agonists, are demonstrating even more impressive weight‑loss outcomes than currently available therapies, with the potential for better tolerability and sustained results,” he told Fox News Digital.
“There is also tremendous optimism around new federal agreements with manufacturers that aim to make these medications more widely accessible and affordable for the broad population of patients who need them most.”
No. 2: More convenient dosing
The typical prescription for a GLP-1 medication is a weekly injection, but delivery and dosing may be changing to more convenient methods in 2026, according to Balazs.
OPRAH JOINS WAVE OF CELEBRITIES WHO REVEALED DRAMATIC WEIGHT LOSS IN 2025
A daily 25 mg pill version of Novo Nordisk’s Wegovy, a semaglutide designed to treat obesity, is now approved and available for chronic weight management, offering a non-injectable option for some patients.
A once-weekly oral GLP-1 is currently in phase 2 trials, as well as an implant that aims for three to six months of drug delivery, Balazs noted.

No. 3: Less invasive surgery
In addition to decreased risk during surgery for GLP-1 users, Balazs also predicted that metabolic surgery without incision will rise as a better option.
“Incisionless endoscopic procedures — like endoscopic sleeve gastroplasty (non-surgical weight-loss procedure that makes the stomach smaller from the inside) and duodenal mucosal resurfacing (non-surgical procedure that resets part of the small intestine to help the body better handle blood sugar) — [may become] more durable and widely available,” he said.

“These offer significant metabolic benefits with shorter recovery and lower risk than traditional surgery.”
Rabito agreed that “rapid progress” in minimally invasive weight‑loss procedures is “opening powerful new options for patients who are hesitant to pursue traditional bariatric surgery.”

This avenue offers “meaningful and durable weight reduction with less risk, shorter recovery times and no external incisions,” the expert added.
Dr. Muhammad Ghanem, bariatric surgeon at the Orlando Health Weight Loss & Bariatric Surgery Institute, reiterated that surgery remains “the most successful modality for the treatment of obesity … with the highest weight loss and most durable outcomes as of yet.”
No. 4: Younger GLP-1 users
As Novo Nordisk’s Wegovy has been indicated for adolescents over 12 years old as an obesity treatment, Balazs commented that pediatric use of weight-loss drugs is “now a clinical reality.”
He predicted that other alternatives are likely to be approved in 2026 for younger users.
No. 5: High-tech, personalized access
Amid the growth of artificial intelligence, Balazs predicted an expansion in the clinical implementation of AI-driven weight-loss methods.

This could include categorizing obesity into sub-types like “hungry brain,” “emotional hunger” and “slow burn” to personalize how therapy is prescribed while moving away from “trial and error,” he said.
Ghanem agreed that there will likely be a “big focus” on individualized testing for causes of obesity in 2026, as it’s a disease that can have “different causes in different people,” thus requiring different treatments.
AI and other digital opportunities will drive more access for weight-loss patients, experts say. (iStock)
The doctor anticipates that more patients will seek combinations of comprehensive treatments and programs.
“Patients are more aware that now we have a few weapons in our arsenal to combat obesity, and [they] are seeking a multidisciplinary and holistic approach,” Ghanem said.

Treatment options will also turn digital with the rise of prescription digital therapeutics (PDTs) for weight loss, Balazs predicted.
“These are software applications delivering cognitive behavioral therapy, personalized nutrition and metabolic coaching through algorithms, often integrated with continuous glucose monitors, and reimbursed as medical treatments,” he said.

Ghanem added that body composition analyzers, like DEXA scans, will likely be more widely used as awareness grows about the limitations of BMI and weight in assessing obesity.
Congratulations, you’ve reached the final day of the Brain Health Challenge! Today, we’re asking you to do a few things that might feel a bit out of left field — like getting your blood pressure checked.
No, it isn’t as fun as playing Pips, but experts say it’s one of the most important things you can do for your brain. That’s because heart health and brain health are intrinsically linked.
High blood pressure, in particular, can damage brain cells, and it’s a significant risk factor for stroke and dementia. When blood pressure is too high, it places stress on the walls of arteries in the brain. Over time, that added stress can cause the blood vessel walls to thicken, obstructing blood flow. In other cases, the increased pressure causes the artery walls to thin and leak blood into the brain.
These changes to the blood vessels can sometimes cause a large stroke to occur. More commonly, the damage leads to micro-strokes and micro-hemorrhages, which cause fewer immediate problems and often go unnoticed. But if someone has hypertension for years or decades, these injuries can build up, and the person may start to experience cognitive impairment.
High blood pressure “is known as a silent killer for lots of reasons,” said Dr. Shyam Prabhakaran, the chair of neurology at the University of Chicago. “It doesn’t cause you any symptoms until it does.”
Because the damage accumulates over many years, experts say that managing blood pressure in midlife matters most for brain health. Hypertension can be addressed with medication or lifestyle changes, as directed by your doctor. But the first thing you need to do is know your numbers. If your blood pressure comes back higher than 120/80, it’s important to take it seriously, Dr. Prabhakaran said.
While you’re at it, there are a few other aspects of your physical health that you should check on.
Your eyes and ears are two of them. Hearing and vision loss have both been shown to increase the risk of dementia. Experts think that with less sensory information coming in to stimulate the brain, the regions that process hearing and vision can start to atrophy. What’s more, people with sensory loss often withdraw or are left out of social interactions, further depriving them of cognitive stimulation.
Oral health can also affect your brain health. Research has found a connection between regular flossing and reduced odds of having a stroke. That may be because good oral health can help to reduce inflammation in the body. The bacteria that cause gum disease have also been tied to an increased risk of Alzheimer’s.
And have you gotten your shingles vaccine? There is mounting evidence that it’s a powerful weapon for protecting against dementia. One study found that it lowered people’s odds of developing the condition by as much as 20 percent.
To wrap up this challenge, we want you to schedule a few medical appointments that benefit your brain, as well as your body.
After five days of feeding, exercising and challenging your brain, you are well on your way to better cognitive health. Thanks for joining me this week, and keep up the good habits!
