Weight loss is usually considered a good thing, unexpected and extreme weight loss can be a sign of something in your body going very wrong. There could be some underlying issues that are causing your body to pull weight and nutrition from your muscles and body fat to keep you going. As you grow old, your limbs grow weaker, and same for your muscles, so you do lose some weight as you age, but losing a lot of it too quickly could be a sign of something much worse, Dementia. A recent study published in JAMA Network Open 2025 Cardiometabolic Trajectories Preceding Dementia in Community-Dwelling Older Individuals, has identified potential early indicators of dementia, including significant weight loss and specific digestive changes, appearing years before noticeable cognitive decline.

The study showed that people who later got dementia had their Body Mass Index, or BMI, go down faster than those who stayed healthy. BMI is a way to see if someone's weight is healthy for their height. This drop in BMI started happening many years before they were told they had dementia, sometimes as early as 11 years ago. Also, these people often started with a lower BMI to begin with. So, even though everyone's weight might change a little as they get older, the people who developed dementia had a much bigger and faster weight loss.

What Are Some Other Indicators Of Dementia?

Along with their BMI, the size of their waist also changed. People who ended up with dementia had smaller waist sizes, and this difference was noticeable about 10 years before they were diagnosed. This means that their bodies were changing in ways that showed up long before they or their doctors noticed any problems. So, not only was there weight loss, but also a loss of abdominal fat. This measurement is important because fat around the waist can be related to other health issues.

The study also found changes in their blood. Specifically, the "good" cholesterol, called HDL, went up in people who developed dementia. This increase happened about five years before they were diagnosed. It's tricky because HDL is usually seen as a good thing for your heart. But in this case, it seems like it might be a sign of changes happening in the brain. Scientists are still trying to understand why this happens.

Weight Loss Doesn’t Cause Dementia, Dementia Causes Weight Loss

When we see that people with dementia lose weight, it's easy to think that the weight loss is what caused dementia. But experts think it's the other way around. They call this "reverse causation." This means that the brain changes that cause dementia also cause people to lose weight. The brain changes can affect things like appetite, how the body uses food, and how people go about their daily lives. For example, people might forget to eat, have trouble making meals, or move around less.

While the study revealed a lot about different indicators of dementia and bodily changes, there are many limitations to the study. Everyone loses some weight as they get older. So, it's hard to know when weight loss is just a normal part of aging and when it's a sign of dementia. The study found that people with dementia lost weight faster, but it's still tricky to tell the difference in everyday life. Doctors need to look at other things, like memory tests, to figure out if someone's weight loss is a cause for concern.

If someone is losing weight without trying, and they're also having problems with their memory or thinking, it's important to talk to a doctor. It's not just about the weight loss; it's about the whole picture.

What Is MenB Vaccine?

London School of Hygiene & Tropical Medicine noted that over a dozen people are seriously unwell in hospital and two people have died from an outbreak of meningitis in the UK. As per the UK Health Security Agency, illness may have spread during an event attended by students in Kent. Four cases have been confirmed to be meningitis B through laboratory testing.

As per NHS UK, menB vaccine offers protection against meningococcal group B bacteria, which is identified to be the strain that has infected people. The vaccine is recommended for babies aged 8 weeks, followed by a second dose at 12 weeks and a booster at 1 year.

Who Should Get MenB Vaccine?

As per the University of Oxford, MenB vaccine is given to babies at 8 weeks, 16 weeks, and one year of age.

General Practitioner surgery or clinic also send an appointment for babies to have their MenB vaccination along with their other routine vaccinations.

Additional doses of the vaccine are recommended for people with some long-term health conditions who are at greater risk of more severe meningococcal disease. This includes people with:

  • asplenia or splenic dysfunction (a spleen that is missing or does not work properly)
  • sickle cell anaemia
  • coeliac disease
  • complement disorders (the complement system is an important part of the immune system, and disorders of this system can increase a person’s risk to some diseases.)

The University of Oxford noted that from August 2025, the MenB vaccine has been offered primarily to gay, bisexual and other men who have sex with men, in a targeted programme to prevent cases of gonorrhoea. This is because these groups of people are at higher risk of acquiring gonorrhoea.

How Does Meningitis B Spread?

Neisseria meningitidis is most commonly found living in the throat. It is spread between people through close contact with secretions from the mouth or airway and usually requires close or prolonged contact between people for the bacteria to be transmitted.

Common Symptoms Of Meningitis

  • Headaches
  • Neck stiffness
  • Fever
  • Drowsiness
  • Nausea or vomiting
  • Increased sensitivity to light

Some meningitis infections can also cause a rash that does not disappear with pressure. However they may not be always visible in the early stages.

No Refrigeration Needed: New Vaccine May Expand Immunization Worldwide

Updated Mar 17, 2026 | 10:00 PM IST

SummaryA new thermostable vaccine that remains effective at room temperature has shown promising results in early trials. Scientists say the technology could reduce vaccine wastage, simplify distribution and improve immunization access in remote regions worldwide.

Vaccines are among the most powerful tools in modern medicine, preventing millions of deaths each year. Yet getting those vaccines safely from laboratories to people who need them is far more complicated than many realise. Most vaccines must be kept within a strict temperature range between 2°C and 8°C from the moment they are produced until they are administered.

This temperature controlled system, known as the cold chain, depends on refrigerators, insulated transport boxes and a steady supply of electricity at every step of the journey. Any disruption can damage the vaccine and make it ineffective. Now, scientists are testing a new technology that could remove this challenge altogether.

A vaccine designed to remain stable even at room temperature has shown encouraging results in an early human trial. Researchers believe this could change how vaccines are distributed, especially in regions where refrigeration is difficult to maintain.

The Challenge Of Keeping Vaccines Cold

Vaccines are sensitive biological products. Exposure to excessive heat or freezing temperatures can damage their active ingredients and reduce their ability to trigger an immune response.

To avoid this, countries rely on a carefully managed cold chain that transports vaccines from manufacturing facilities to warehouses, regional storage centers and finally to clinics. This process requires specialised equipment, trained staff and constant monitoring of temperatures.

However, maintaining this system is both expensive and complex. Equipment failures, power outages and transport delays can disrupt the cold chain at any stage. In rural or remote regions where electricity supply is unreliable, these challenges become even more serious.

Global health experts estimate that a large number of vaccines are lost every year because of temperature control failures during storage and transport. This leads to wasted doses, increased costs and gaps in vaccination coverage.

Because of these difficulties, scientists have long been searching for ways to develop vaccines that can remain effective without strict refrigeration.

A Vaccine That Can Survive At Room Temperature

One promising development is a vaccine candidate called SPVX02, which targets tetanus and diphtheria. It has been developed by the biotechnology company Stablepharma with support from the UK Health Security Agency.

What makes this vaccine different is the technology used to stabilize its active ingredients. The formulation allows the vaccine to tolerate higher temperatures without losing potency.

Early findings from a Phase I clinical trial suggest the vaccine can remain stable at around 30°C for as long as two years. The study was carried out at the Vaccine Development and Evaluation Centre in the United Kingdom and involved healthy volunteers.

Phase I trials are the earliest stage of human testing. At this stage, researchers focus mainly on safety, possible side effects and the body’s immune response.

If further trials confirm these findings, the same stabilization technology could potentially be applied to other vaccines as well.

Why This Could Matter For India

A fridge free vaccine could have major implications for countries such as India, which runs one of the largest immunization programmes in the world.

India’s Universal Immunisation Programme delivers vaccines to millions of children every year. To reach remote villages and urban settlements, the programme depends on a vast cold chain network that includes refrigerated storage facilities, specialized transport and vaccine carriers.

Maintaining this infrastructure across a country with varied climates and uneven electricity supply can be difficult. Heat exposure during transport or power failures can lead to spoilage and wastage.

A thermostable vaccine that remains effective at room temperature could simplify this process significantly. It would reduce dependence on refrigeration, lower costs and make it easier to deliver vaccines in remote or resource limited areas.

What Happens Next

Although the early results are encouraging, the vaccine still needs to go through larger clinical trials before it can be approved for widespread use.

Future studies will involve more participants and compare the new formulation with existing refrigerated vaccines to confirm its effectiveness.

If the technology proves successful, researchers believe it could be adapted for many other vaccines in the future. That possibility could reshape how immunization programmes operate worldwide and help bring life saving vaccines to communities that have long struggled to access them.

A federal judge in Massachusetts has blocked a series of vaccine policy changes introduced by U.S. Health Secretary Robert F. Kennedy Jr., dealing a significant setback to the Trump administration’s health agenda. The ruling temporarily halts new vaccine recommendations and reverses recent decisions made by the government’s vaccine advisory panel.

The decision was issued by Judge Brian Murphy of the U.S. District Court for the District of Massachusetts. It came after several medical organizations argued that the government’s actions were not based on scientific evidence and could endanger public health.

Court Says Science Was Ignored

In his ruling, Judge Murphy said vaccine policy decisions have traditionally been based on careful review of scientific data. This process is also required under federal law.

However, he wrote that the government had ignored these standards while introducing changes to vaccination guidelines. According to the court, the decisions undermined the integrity of the process that normally guides national immunization recommendations.

The ruling stops the government from implementing those changes for now. It also means the Advisory Committee on Immunization Practices, or ACIP, cannot hold its scheduled meeting this week.

Lawsuit From Medical Organizations

The case was brought by six major medical organizations, including the American Academy of Pediatrics. They claimed that the new policies changed the childhood vaccine schedule without proper scientific review.

The groups argued that the government had made “arbitrary and capricious” decisions by bypassing the usual evidence-based process. They also questioned the qualifications of several members appointed to the vaccine advisory committee.

Judge Murphy noted in his ruling that only six of the 15 committee members appeared to have meaningful experience with vaccines. The committee is responsible for recommending which vaccines Americans should receive and when.

Changes to Childhood Vaccine Schedule

The lawsuit focused on a series of policy changes introduced over the past year. These included reducing the number of diseases covered under the routine childhood immunization schedule.

In January 2026, federal officials announced a new vaccine schedule that lowered the number of diseases children are routinely vaccinated against from 17 to 11.

The changes also affected recommendations for Covid vaccines. Earlier in 2025, Kennedy announced that Covid shots would no longer be recommended for healthy children or pregnant women.

Health officials supporting the changes argued that growing mistrust of vaccines had reduced vaccination rates. They believed simplifying the schedule might rebuild public confidence.

However, critics said the changes were rushed and not supported by strong scientific review.

Experts Warn About Public Health Risks

Many doctors and public health experts strongly opposed the new policies. They warned that weakening vaccine recommendations could lead to outbreaks of preventable diseases.

Medical groups say childhood vaccination programs have been one of the most successful public health efforts in modern history. Vaccines protect children from serious diseases such as measles, polio and hepatitis B.

Several organizations also filed supporting legal documents in the case, including public health experts and research groups.

Government Likely to Appeal

Officials from the Department of Health and Human Services said the government plans to challenge the ruling. A spokesperson said the administration expects the decision to be overturned.

For now, however, the court order means previous vaccine recommendations will remain in place.

Medical organizations welcomed the ruling. They said it helps restore a science-based process that has guided vaccine policy for decades and protected the health of millions of children.

What Were The Changes Suggested In The Latest CDC Vaccine Schedule?

The federal health department sought to reduce the number of shots American children receive, announced that the new Centers for Disease Control and Prevention (CDC), vaccine schedule will include routine shots for 11 diseases for children. This is down from 17 diseases, which were earlier included. Jim O'Neill, who is the acting director of the CDC updated the agency's immunization schedule to reflect the changes, effective immediately.

The most controversial change is the narrowing of recommendations for several common childhood vaccines. Immunization against the following illnesses is now advised only for high-risk children or after consultation with a health care provider:

  • Hepatitis A
  • Hepatitis B
  • Meningococcal disease
  • Rotavirus
  • Influenza
  • Respiratory syncytial virus, or RSV

Covid-19 vaccination has also shifted to a consultation-based recommendation rather than routine use for all children.

This means shots that were once automatically given at set ages, including at birth, during infancy, and in adolescence, may now depend on individual medical discussions rather than standard guidance.
