Combination nasal spray vaccine could protect against COVID, flu and pneumonia at once
NEWYou can now listen to Fox News articles!
A single spritz could eventually offer simultaneous protection against several infectious diseases.
Researchers at Stanford Medicine have developed a new vaccine that could prevent multiple viruses at once, including COVID-19, influenza and pneumonia.
The vaccine is administered “intranasally” through a nasal spray, which provides “broad protection in the lungs for several months,” according to a Stanford Medicine press release.
Researchers claim this is the closest science has gotten to creating a universal vaccine that protects against respiratory viruses, bacteria and allergens.
The study, published in the journal Science, examined the impact of the vaccine on mice. The animals were given a drop in the nose, some receiving multiple doses a week apart.

Every mouse was then exposed to a respiratory virus. While vaccinated mice saw protection for at least three months, unvaccinated mice experienced dramatic weight loss due to illness, lung inflammation and death. Every vaccinated mouse survived and had clear lungs, the release stated.
The vaccinated mice were also found to be protected against SARS-CoV02 and other coronaviruses, as well as Staphylococcus aureus and Acinetobacter baumannii — which are common hospital-acquired infections — and house dust mites, a common allergen.

The universal vaccine does not target a single virus, but instead trains the immune system in the lungs to “provide broad protection against many different respiratory viruses,” senior study author Bali Pulendran, PhD, a professor of microbiology and immunology at Stanford, told Fox News Digital.

“By reprogramming the innate immune cells that act within hours of infection, the vaccine prepares the lungs to fight off many different respiratory viruses, even new ones,” he said.
“Our findings point toward what may be possible in the future, but they are not a substitute for existing vaccines today.”
If translated to humans, a vaccine like this could replace “multiple jabs every year for seasonal respiratory infections and be on hand should a new pandemic virus emerge,” according to Pulendran.
“Imagine getting a nasal spray in the fall months that protects you from all respiratory viruses, including COVID-19, influenza, respiratory syncytial virus and the common cold, as well as bacterial pneumonia and early spring allergens,” the researcher said. “That would transform medical practice.”
The preclinical trial in mice shows promise, as none of the vaccinated mice died from illness, the researchers shared. (iStock)
The results of the study suggest that the immune system can “be trained to mount a more generalized antiviral defense in the lungs,” Pulendran added.
The researcher acknowledged that the study has some limitations.

It is a preclinical study conducted in animal models, making it an “important proof of concept rather than a finished human vaccine,” Pulendran said.
“While the results are encouraging, additional studies are needed to determine safety, optimal dosing and effectiveness in people,” he added.
The lead researcher predicted that with the necessary funding, the nasal spray vaccine could be available in five to seven years. (iStock)
This research should not change current medical advice, according to Pulendran, and the public should continue relying on approved vaccines and public health guidance.

“Our goal is not to replace current vaccines, but to complement them by developing strategies that could provide an added layer of protection against a wide range of respiratory threats, including future pandemics,” Pulendran added. “Translation to humans will require careful clinical testing.”
The scientists’ next step will be to test the vaccine in humans. With sufficient funding, Pulendran predicts that the vaccine could be available in five to seven years.
The public should continue relying on available vaccinations, the researchers advise. (iStock)
Dr. Robert H. Hopkins, Jr., the Arkansas-based medical director of the National Foundation for Infectious Diseases, confirmed that there has “long been interest” in developing universal vaccines.
Hopkins, who was not involved in the study, cautioned that the immune responses in mice are not identical to those in humans.
“This process is a fascinating concept, and the study is very interesting, but many additional steps need to be completed successfully and safely before this could be considered in humans,” he told Fox News Digital.

“It will likely take many years, require significant financial investment and involve multiple additional studies before we know whether this particular universal vaccine candidate can be safely given to humans and whether it will provide similar protection against respiratory bacteria and viruses.”
The study received funding from the National Institutes of Health, the Violetta L. Horton Professor endowment, the Soffer Fund endowment and Open Philanthropy.

Microwaved squishy toy explodes onto boy’s face and chest amid viral trend, causing horrific burns
NEWYou can now listen to Fox News articles!
An Alabama teenager and his family are warning about the dangers of a viral social media trend after he suffered third-degree burns when a microwaved sensory toy exploded.
Eli Blackmon, now 13, was 11 when he saw videos on TikTok showing people putting NeeDoh squishy toys in the microwave in order to soften them.
The NeeDoh, a sensory toy similar to a stress ball, is described on the company’s website as a “gratifying super soft, super stretchy dough filled groovy glob.”
DANGEROUS TIKTOK TREND LEAVES BOY BADLY BURNED AS DOCTORS ISSUE WARNING
“I thought it was harmless because an adult tried it and nothing happened,” he told Fox News Digital this week.
“When I took it out, my older sister held it for a few minutes, then I was playing with it. As soon as I squeezed it, it burst and the hot gel exploded onto my neck, chest and hands.”

The hot gel caused third-degree burns on the boy’s neck and chest.
“At first I was just feeling frantic because I wasn’t sure what was going on because he was just screaming and not communicating,” the teen’s mother, Fallon Blackmon, told Fox News Digital.
‘BEANTOK’ TREND GOES VIRAL WITH WILD GUT HEALTH PROMISES — HERE’S WHAT EXPERTS SAY
“My husband is a fire medic and I work in emergency call taking, so I had a little knowledge of how serious it was. That obviously didn’t keep me from panicking on the inside.”
She was not aware of this trend before her child’s injury, she said.
“If I was aware, we would have had a conversation about not doing it.”

Eli Blackmon recalled feeling extreme pain after the injury.
“I thought I was going to die. I kept telling my parents, ‘I don’t want to die, I’m sorry,’ and I that I loved them.”
Blackmon was transported by ambulance to the emergency department at the local children’s hospital, and was later sent to the burn unit for wound care and debridement.
‘TANMAXXING’ TREND COULD COME AT A DANGEROUS COST, SKIN CANCER EXPERTS WARN
“With how severe the burn was, they would typically recommend skin grafts, but they wouldn’t consider it for him because of the risks to his airway,” his mother said.

“This was done with no pain meds or numbing, so all his follow-up appointments were very painful,” Fallon Blackmon said.
“Once the wound started to heal and the scarring began, they had to do chemical burns because he was developing granulation tissue.”
“Don’t do it! It’s stupid! It causes so much pain.”
The teen also developed a rash from the bandages, which quickly turned into a staph infection.
“Another issue was that the burn was pulling fluids from his body, and this caused severe lower GI issues for months,” his mother said.

Now, the teen and his mother aim to help prevent other families from going through the same ordeal.
“If you purchase these types of toys, please just mention this trend and not to do it,” she urged parents. “Even if they don’t have social media, kids in school are hearing it from other kids.”

Today, Blackmon attends to his scar each day so that it doesn’t cause any issues with neck mobility.
“I have to do stretches and moisturize and massage it daily,” he said.

“It hasn’t really changed my confidence because all my friends and family are very supportive and tell me my scar is cool.”
To other kids who may be thinking about participating in this social media trend, Blackmon’s advice is simple: “Don’t do it! It’s stupid! It causes so much pain and other problems.”

“Actually, just don’t do any trends on TikTok, even if you think they are harmless,” he added. “Talk to your parents.”
Blackmon’s mother agreed, noting that sharing the story and receiving negative criticism from adults online would be worth preventing another child from being “scarred for life” and experiencing something so traumatic.

Heart condition tied to Lindsey Graham’s death can strike without warning — what to know
NEWYou can now listen to Fox News articles!
New details surrounding Sen. Lindsey Graham’s sudden death have drawn attention to a cardiovascular emergency that can become fatal within minutes.
A statement released by Graham’s office on Sunday cited preliminary findings from the District of Columbia’s Office of the Chief Medical Examiner, identifying the cause of death as an aortic dissection due to arteriosclerotic cardiovascular disease.
Authorities said Graham, 71, was transported to George Washington University Hospital, where he was pronounced dead at 10:23 p.m. Saturday. An autopsy was completed Sunday.
MEDICAL EXAMINER RELEASES PRELIMINARY FINDINGS IN LINDSEY GRAHAM’S DEATH AS DEATH CERTIFICATE REMAINS PENDING
“The death certificate will be PENDING until all the toxicological and microscopic testing are finalized, and at that point the death certificate will be updated to reflect the cause of death and appropriately classify the manner of death,” the statement said.
Fox News Digital reached out to Graham’s office requesting comment.

What is an aortic dissection?
An aortic dissection is a life-threatening medical emergency in which a tear develops in the inner layer of the aorta — the body’s largest artery, according to Mayo Clinic.
“It occurs when the layers of the aorta come apart and the inner one tears,” Fox News senior medical analyst Dr. Marc Siegel, who did not treat Graham, told Fox News Digital.
YOUR RESTING HEART RATE COULD REVEAL MORE ABOUT YOUR HEALTH THAN YOU THINK, DOCTORS SAY
Blood rushes through the tear and causes the layers of the aortic wall to separate, which can disrupt blood flow to vital organs or lead to a fatal rupture if not treated immediately.
“It can come on in minutes or days and may be hard to recognize,” added Siegel, noting that while dissections can evolve over time, symptoms often appear suddenly.

Dr. Kenneth Perry, an emergency physician based in South Carolina, said the best way to visualize the condition is to think of the aorta as a hose.
“The wall of the hose has multiple layers to it, and if the layers separate, the water can no longer pass down the regular opening in the tube,” Perry, who also was not involved in Graham’s care, told Fox News Digital. “Often, this starts as a very small tear that keeps progressing because of the water pressure.”
DIABETES DRUG COULD SLASH RISK OF FATAL HEART CONDITION IN ONE GROUP, SCIENTISTS REVEAL
“The same thing is happening in the aorta,” he went on. “The small tear in the wall of the aorta continues to progress, usually from severely elevated blood pressure.”
As the tear continues past the smaller arteries coming from the aorta, blood can no longer flow from the heart to the other organs.

“This causes the organs that need that blood to die from lack of oxygen,” Perry said. “The only way to survive such a diagnosis is very early identification and strict blood pressure control with emergent operative management.”
Aortic dissection is relatively rare, affecting an estimated three to four people per 100,000 each year, according to Cleveland Clinic.
What causes an aortic dissection?
In Graham’s case, the preliminary findings cited arteriosclerotic cardiovascular disease. This condition is most commonly associated with atherosclerosis, in which plaque builds up inside the arteries, causing them to harden and narrow.
Over time, this process can weaken the wall of the aorta, increasing the risk of an aortic dissection.
“It can come on in minutes or days and may be hard to recognize.”
High-risk groups
Arteriosclerotic cardiovascular disease can develop over time and is driven by several factors, according to the American Heart Association and Mayo Clinic.
Some of the groups at highest risk include the following.
- People with uncontrolled high blood pressure (hypertension), which places constant stress on the aortic wall
- Older adults, particularly those in their 60s and 70s
- Men, who are diagnosed more often than women
- People with atherosclerosis (hardening of the arteries) or other cardiovascular disease
- Those with an aortic aneurysm, which weakens the wall of the aorta
- People born with certain heart defects, such as a bicuspid aortic valve
- Those with inherited connective tissue disorders, including Marfan syndrome, Loeys-Dietz syndrome and vascular Ehlers-Danlos syndrome
- Smokers and people with longstanding high cholesterol, both of which contribute to artery damage
- People with diabetes and obesity
- Those who are physically inactive and/or eat an unhealthy diet

“Graham’s father had a cardiac arrest, and if it was from a dissection, it would increase the risk,” Siegel noted.
Warning signs you should never ignore
Symptoms of an aortic dissection can come on suddenly and often mimic those of a heart attack or stroke, experts say.
Anyone experiencing any of the below warning signs should call 911 for immediate emergency medical care, according to Siegel and other health experts.

- Sudden, severe chest or upper back pain, often described as tearing, ripping or stabbing, which may spread to the neck or back
- Shortness of breath
- Sudden, severe abdominal pain
- Loss of consciousness (fainting)
- Stroke-like symptoms, such as sudden vision changes, difficulty speaking, weakness or numbness on one side of the body
- Leg pain or difficulty walking

“Aortic dissection is one of the diseases that emergency physicians think of often when someone presents with chest pain — specifically pain described as a tearing sensation, with elevated blood pressure,” Perry told Fox News Digital.
“We often describe the aortic dissection patient as appearing to have a ‘kidney stone of the chest,’ — meaning they have severe pain and cannot get comfortable, similar to kidney stone patients.”
Diagnosis and treatment
Early diagnosis and treatment greatly improve the chances of survival for those who have suffered an aortic dissection.
Doctors typically diagnose an aortic dissection using imaging tests, including a CT scan, transesophageal echocardiogram (ultrasound), magnetic resonance angiography (MRI-based scan) and chest X-ray, per Mayo Clinic.

The condition requires immediate medical treatment, which will depend on which part of the aorta is affected.
Type A dissections involve the ascending (upper) aorta near the heart, which typically require emergency surgery.
According to the American Heart Association, an untreated acute aortic dissection is one of the deadliest cardiovascular emergencies. (iStock)
Type B dissections affect the descending (lower) aorta farther from the heart, according to Mayo Clinic. These may be treated with medications to lower blood pressure and heart rate, although some may also require surgery or a stent.
Those who survive the event will generally need lifelong blood pressure management and regular imaging to monitor the aorta, per the above source.

“This condition has a high mortality rate,” Siegel said.
According to the American Heart Association, an untreated acute aortic dissection is one of the deadliest cardiovascular emergencies.
“We often describe the aortic dissection patient as appearing to have a ‘kidney stone of the chest.’”
For untreated dissections involving the ascending aorta, the risk of death increases by approximately 1% to 2% for every hour treatment is delayed after symptoms begin, according to the American College of Cardiology and the American Heart Association.
Without treatment, more than half of people with a Type A aortic dissection die within one month. About 20% of Type A patients will die in the hospital, compared to 10% for treated Type B dissections.
Can it be prevented?
While not all aortic dissections can be prevented, people can reduce their risk by controlling certain lifestyle factors.
“You need to make sure your blood pressure is well-controlled, your cholesterol is low and that you are seen regularly by a doctor,” Siegel advised.
Smokers should kick the habit, he said, as they are at a highly increased risk.

Maintaining a healthy weight and following treatment plans for underlying heart or vascular conditions can also reduce the risk, according to Mayo Clinic.
People with a family history of aortic disease or inherited connective tissue disorders should discuss screening with their healthcare provider, doctors advise.
