Nasal Covid Vaccine May Be the Next Big Thing, Here’s All That You Need to Know

In the journal <span>Science Advances</span>, the researchers on July 31 reported that hamsters receiving nasal vaccines did not pass on the virus to other healthy hamsters. Despite being infected themselves, the nasal vaccine was able to stop the transmission, and it may be the future of all vaccines. It has the potential to stop the spread from person to person.

<h5>How does it work?</h5>The researchers have noted that vaccination through nose and mouth can better control the spread of respiratory diseases like influenza and COVID-19. The key to preventing transmission is ensuring that virus levels remain low in the upper airways. Researchers have found that mucosal vaccines do ensure that the virus levels remain low by limiting the viral replication in the upper airways.  

The injectable vaccines which came out because of COVID-19 though reduced illness and deaths, did not prevent the spread of the virus. As the vaccines are less potent in the nose and it leaves the nose unprotected, often exposed to viruses that can multiply in the upper airways.

Whereas mouth or nasal spray can reduce the transmission and trigger the immune response to the world where it is required.

<h5>The Hamster Test</h5>Scientists used a two-step process, where they tested the nasal vaccine that was used in India against the injectable <span>Pfizer</span> vaccine on the hamsters. The reason why the test was done on hamsters is because hamsters are more prone to COVID-19, making them better lab animals than mice for this test. 

The test included placing the vaccinated hamsters who were given enough time to be fully immune with infected hamsters for eight hours. The results showed that 12 of the 14 nasally vaccinated hamsters had 100 to 100,000 times lower virus levels than the 15 of the 16 hamsters who got the shot.  

For the second step, the scientists took the infected hamsters who were vaccinated and put them with healthy hamsters for another eight hours. As a result, none of the healthy hamsters who were kept with nasally vaccinated hamsters were infected. Whereas, half of the new hamsters who were exposed to hamsters vaccinated by injection became infected.

As a result, the scientists are of the view that nasal vaccination can be the new breaking into resolving the spread of viruses and reducing the cases of respiratory diseases. The nasal vaccine also has fewer chances of side effects.

This Common Energy Drink Ingredient Is Tied To Blood Cancer Risk

this common energy drink ingredient is tied to blood cancer risk

For years, type 2 <span>diabetes</span> has been viewed as a metabolic disorder rooted in lifestyle habits, obesity, and insulin resistance. But a new study, released in the Journal of Clinical Investigation, is challenging that underlying wisdom. In a stunning reversal, researchers have discovered that certain neurons in the brain specifically Agouti-related peptide (AgRP) neurons in the hypothalamus could play an important role in the onset and resolution of type 2 diabetes.

This finding opens the door to an innovative treatment strategy- conditioning the brain to control blood sugar levels, perhaps without changing weight or food consumption. It's a breakthrough that can reimagine how the global medical community treats this chronic illness that plagues more than 400 million people around the world.

Up to this point, the brain was not thought to play a central role in type 2 diabetes pathology. However, investigators at UW Medicine have demonstrated that a hyperactive population of neurons, <span>AgRP neurons</span> found in the arcuate nucleus of the hypothalamus disproportionately contribute to driving hyperglycemia (elevated blood glucose).

Dr. Michael Schwartz, lead author on the study and a leading endocrinologist at the University of Washington, said, "These neurons are having an outsized impact in hyperglycemia and type 2 diabetes." His researchers silenced the talking capability of AgRP neurons with viral genetics—namely, they introduced tetanus toxin to keep these neurons from talking to nearby cells. The findings were nothing short of revolutionary: blood glucose levels normalized for months in diabetic mice, even without adjustments in body weight or food consumption.

This finding contradicts the long-held dogma that weight gain and insulin resistance are the central causes of type 2 diabetes. Lifestyle and genetics are still major players, of course, but the brain's regulatory role in glucose metabolism is also proving to be a major if not central component of the puzzle.

The scientists observed additional modifications in the mice after AgRP neuron repression:

<ul><li>Lower plasma insulin levels, indicating higher insulin sensitivity</li><li>Higher liver glycogen, reflecting more effective glucose storage</li><li>Lower corticosterone (mouse equivalent of cortisol), which could indicate reduced physiological stress</li><li>Higher lactate levels, potentially increasing hepatic glucose uptake</li></ul>

These indicators as a whole indicate systemic restoration of glucose metabolism—initiated not by a pancreas-directed or weight-loss intervention, but by a brain-mediated one.

<h2>How This Research Relates to Ozempic?</h2>

Surprisingly, today's diabetes medications such as GLP-1 receptor agonists like the blockbuster medications Ozempic and Wegovy—are also known to suppress AgRP neurons. Dr. Schwartz theorizes that these brain-targeting actions may be a partial explanation for their glucose-lowering effects, independent of their well-characterized effect on weight loss.

The degree to which this effect underlies the antidiabetic action of these drugs is unknown," Schwartz said. But the link raises tantalizing possibilities: might stimulating or duplicating this brain suppression be a new, more effective route to remission from diabetes?

<h2>What Implications It Has For Humans?</h2>

Although models in animals are not always a good predictor of human outcomes, the repeatability across several mouse studies is encouraging. An earlier study by Schwartz's group had demonstrated that infusing the brain peptide FGF1 directly into the hypothalamus also resulted in diabetes remission—a response that was again linked to the suppression of AgRP neuron activity.

If the same mechanisms exist in humans, neuromodulation or precision-targeted drugs that quiet particular brain circuits could be future treatment—potentially presenting a backup for patients who have difficulty with lifestyle interventions or develop drug resistance.

<h2>Is Brain-Targeted Diabetes Therapies the New Treatment?</h2>

There are more questions than answers. Why do AgRP neurons get hyperactive in the first place? Can their activity be selectively and safely reduced in human beings? And could this be achieved without impacting other vital functions of the brain?

Dr. Schwartz points out that the study breaks with conventional thinking on diabetes and requires further investigation into the neurobiology of metabolic illness. "This could be a paradigm shift in how we approach and treat type 2 diabetes," he says.

The long-term aim is to translate this brain-based strategy from the bench to the bedside. Successful, it could not only transform diabetes care—it could also lead to greater interest in how the brain controls whole-body metabolism, with the potential for breakthroughs for other diseases linked to metabolic dysregulation.

With millions living with type 2 diabetes globally, the potential of a brain-based treatment framework is staggering. Learning that a few thousand neurons have the power to control blood sugar levels separate from weight loss may change the way the disease is treated, possibly putting an end to the suffering of patients who have long been battling traditional treatments.

As science continues to advance, the neurobiology of metabolism could become the new frontier in international diabetes management. The mind-body connection, it seems, might be more literal and potent than we ever envisioned.

United States (US) is witnessing a concerning surge in <span>measles</span> cases, with more than 1,000 reported so far since the beginning of 2025. This is only the second time since the disease was declared eliminated in America 25 years ago that the number of cases has risen this high. A widespread outbreak spanning at least 30 American states continues to escalate, placing the country on course for what could become the worst year for measles since 2000. 

On Friday, at least 1024 cases of the disease were reported of the highly contagious disease. In 2024, the total number of cases reported were 285. Cases have been reported by 30 states, and there have been 14 outbreaks. Most cases—947 out of the total 1024—are outbreak associated. Meanwhile, the vaccination status of 96% of all cases is classified as "unvaccinated or unknown."

Health and Human Services Secretary Robert F Kennedy Jr has continuously downplayed the outbreak. After the death of a 6-year-old boy in February, Kennedy said the child’s death was "not unusual." "We have measles outbreaks every year,” he said at the time." But this spread is unlike others the US has previously seen, becoming the second-highest case count in 25 years. After facing criticism, Kennedy slightly walked back his comments after attending the funeral of an 8-year-old Texas girl who died from measles at the start of April. 

Ever since then, Kennedy Jr has continued to downplay the disease. In April, he baselessly claimed that the <span>measles vaccine</span> "contains a lot of aborted fetus debris and DNA particles. He then went on a TV appearance to tell parents to "Do your research" on vaccines, without specifying any information sources. In the latest development, he asked people not to follow his medical advice. 

US health secretary Kennedy Jr refused to say whether he would vaccinate his children if he had to choose today, and defended Republicans’ proposal to cut healthcare to fund tax cut extensions.  “What I would say is my opinions about vaccines are irrelevant … I don’t want to seem like I’m being evasive, but I don’t think people should be taking advice, medical advice, from me."

As so much of the world adjusts to a new beat of post-pandemic existence, the virus responsible for one of the 21st century's most significant worldwide health crises continues to mutate, perturb, and resurface. In the past few weeks, Southeast Asia has been back in the international limelight, with high Covid-19 case spikes reported in Hong Kong and Singapore—two of the world's most important international centers. The episode has created fresh alarm about whether Asia is on the cusp of a second wave of pandemics, and what implications that has for the health world.

Latest figures from Southeast Asian health ministries show a sudden spike in Covid-19 cases in Hong Kong, Singapore, China, and Thailand. In Singapore, the Ministry of Health's infrequent update—its first in almost a year—registered a 28% increase in weekly cases to 14,200 in the week up to May 3. Daily hospital admissions have also risen around 30%.

At the same time, Hong Kong is also facing a sharp spike. The Centre for Health Protection reported that the rate of positivity of respiratory samples jumped from 1.7% in mid-March to 11.4%—higher than the peak reached in August 2024. There have been 30 deaths among 81 severe adult cases over the last month, most involving people above 65 and with prior medical conditions.

The trend is troubling and part of a larger pattern spreading across the region. Thailand saw new clusters of infections after its heavily promoted Songkran holiday in April, and mainland China's test positivity rates have increased by more than two times since late March, nearing that of its summer 2024 wave.

<h2>What's Fueling the Latest Covid-19 Surge in 2025?</h2>

The increase in Covid cases does not seem to be driven by much more virulent strain. Singapore's health ministry reports that the leading strains—LF.7 and NB.1.8, both offshoots of the JN.1 Omicron branch—do not at this moment have higher rates of transmission or severity compared to previous strains.

Rather, specialists attribute a blend of declining immunity and enhanced public mobility as the most probable causes. Booster vaccination rates have declined throughout the region, and without any dramatic changes in variants, numerous individuals have presumed the danger has reduced. But as immunity wears off with time and preventive measures such as masking and distancing are forsaken, populations become more vulnerable to infection—even from previously circulating strains.

Seasonality has also diminished. In contrast to other respiratory diseases that rose during winter months, Covid-19 continues to confound seasonal patterns, with waves now mounting even as the Northern Hemisphere enters summer. This unpredictability highlights the endemic character of the virus—and the necessity for vigilance to continue.

Asian governments are reacting cautiously, but not alarmingly. Singapore has urged high-risk individuals—such as the elderly and immunocompromised—against taking an extra dose of vaccine if over a year has lapsed from their previous shot. It has also reminded everyone of the need for face-masking in crowded areas, hand washing, and self-isolation when unwell.

In Hong Kong, higher viral loads in sewage and rising medical consultations for respiratory symptoms have led authorities to term activity as "quite high." Public awareness campaigns are being reinstated, and local politicians are demanding stronger protection for the vulnerable.

China and Thailand also have recognized the increase but are not imposing limiting measures. They're instead urging citizens to stay current with their vaccinations and exercise personal caution.

<h2>What Are the Symptoms of the New Covid Variants in 2025?</h2>

As typical Covid-19 presentation through fever, cough, and sore throat continues to be widespread, new strains are manifesting with varied symptom patterns. Of specific note is anosmia (loss of smell), an earlier signature presentation that waned with Omicron but has been increasingly reported more recently with JN.1 infection, particularly in Europe.

Medical professionals also continue to point to the risk of Long Covid—ongoing symptoms like fatigue, shortness of breath, and brain fog—that even for mild infections can continue indefinitely. These long-term symptoms are still a big concern for international health systems and are yet another reason that ongoing monitoring and mitigation strategies are needed.

<h2>Is the World Ready for Another Wave?</h2>

Although today's reality in Asia does not yet justify claims of a fresh world wave, the trends are familiar—and ominous. Covid-19's recurrence in largely vaccinated, metropolitan populations serves as a reminder that the disease never vanished. It merely adapted, evolved, and learned how to take advantage of gaps in immunity and behavior.

For the time being, international health officials are waiting closely. The World Health Organization has not issued new warnings but remains monitoring mutations and case trends. Priority is being kept on safeguarding high-risk populations, accelerating lagging vaccination programs, and maintaining health systems' ability to endure localized surges.

The recent surge in Covid-19 cases throughout Asia might not foretell a crisis of 2020 scale, but it marks a crucial stage in the evolution of the pandemic. The virus is endemic—but dynamic. It needs adaptive, flexible responses that weigh public health against everyday existence.

As countries move through this next stage, the lesson continues: complacency is the enemy. Vigilance, vaccination, and responsible public action are still our best weapons for keeping one step ahead of Covid-19, whether in Asia, the U.S., or anywhere else on the planet.
