Heart attacks and strokes are among the leading causes of death globally, with millions suffering from cardiovascular diseases (CVD) every year. There are more than seven million people in the UK alone, with about 100,000 patients experiencing heart attacks annually. However, a group of researchers at University College London (UCL) estimate that one 'polypill' taken daily day could eliminate a majority of these cases dramatically lowering death tolls.
The proposed polypill, a combination of a statin and three blood pressure-lowering drugs, has been under study for over two decades. Experts argue that introducing this pill universally for individuals aged 50 and above could be more effective than the current NHS Health Check, which assesses risk factors every five years for those aged between 40 and 74.
Studies have repeatedly proven the effectiveness of the polypill in preventing CVD. A groundbreaking 2019 study in The Lancet found that five years' use of the polypill cut the risk of heart attack and stroke by a third. In addition, previous modelling analyses have estimated that if given universally to people over 55, the polypill might be able to prevent 80% of heart attacks and strokes.
Today, the NHS Health Check follows a risk-based model in which patients are tested for CVD risk factors and treated with drugs accordingly. Yet, as per UCL's study, this system has serious flaws:
Low Uptake: Just 40% of those eligible for the NHS Health Check choose to have it, leaving a considerable number of at-risk patients undiagnosed and untreated.
Ineffective Prediction of Risk: The majority of heart attacks and strokes happen to people at average risk levels, thus making it challenging to identify the need for intervention effectively.
Limited Effectiveness: Even at maximum take-up, the NHS Health Check programme is predicted to have fewer health impacts compared to a polypill initiative applied to the whole population.
One of the big benefits of the polypill is that it is so easy. In contrast to the existing screening-based model, the polypill scheme would not involve complicated medical tests or lengthy risk assessments. Instead, people reaching 50 would just have to fill out a few questions to determine possible side effects before they were prescribed.
Professor Aroon Hingorani of the UCL Institute of Cardiovascular Science, one of the strongest proponents of this scheme, says:
"Finally, the time is now to do much better on prevention. A population approach would prevent a lot more heart attacks and strokes than is done today with a strategy of trying to target a smaller group only."
Aside from the possible health implications, the polypill is also an economic solution. The drugs used are off-patent, thus cheap to produce and distribute. With the vast economic cost of managing CVD-related illnesses, a preventive model could result in substantial cost-saving for the NHS in the future.
The polypill has been proven to be effective by numerous international trials. In 2019, a randomised trial in rural Iran discovered that participants who took the polypill for five years had a 34% reduced risk of having a heart attack or stroke compared to non-participants.
Likewise, modelling research has indicated that even if only 8% of people aged over 50 took up the polypill regimen, it would still be more beneficial to their health than the NHS Health Check programme.
One of the main objections to the polypill strategy is the suggestion that it might result in the unnecessary medicalisation of a significant proportion of the population. But, it is argued, it should be considered as a preventative measure, not as mass medication.
Professor Sir Nicholas Wald of UCL's Institute of Health Informatics explains:
"Instead of being a 'medicalisation' of a significant proportion of the population, a polypill programme is a prevention measure to prevent an individual from becoming a patient."
He compares it with public health measures like water fluoridation or compulsory seatbelts—interventions that have been shown to have a significant impact in reducing public health danger at low individual cost.
With the evidence in favour of the polypill's effectiveness and viability overwhelming, experts are calling on the NHS to act now. It is their belief that substituting the NHS Health Check with a polypill-based prevention program could be the UK government's flagship policy under its pledge to put disease prevention ahead of cure.
As Professor Hingorani points out, "The status quo is not a justifiable option." With CVD still a major cause of death globally, taking a population-wide polypill approach could be a turning point for preventative medicine, potentially saving thousands of lives annually. The question now is whether the NHS will take up this call and establish a policy with the potential to transform the prevention of cardiovascular disease on a national level.

A total of 52,10,302 girls across India have received the Human Papillomavirus (HPV) vaccine under the nationwide campaign launched by Prime Minister Narendra Modi in February, the government informed Parliament during the ongoing Monsoon Session.
The nationwide vaccination campaign for 14-year-old girls was launched from Rajasthan's Ajmer as part of India's efforts to eliminate cervical cancer.
“The nationwide HPV vaccination campaign was launched on February 28, for approximately 1.2 crore eligible beneficiary girls aged 14 years across all 36 States and Union Territories. As of July 15, a total of 52,10,302 girls have received the HPV vaccine across the country,” Union Minister of State for Health and Family Welfare Anupriya Patel said in a written reply in the Rajya Sabha.

The Minister said the HPV vaccine is being provided free of cost at designated government health facilities, including:
She also said the government's cervical cancer prevention strategy includes HPV vaccination, screening, early diagnosis at Ayushman Arogya Mandirs (AAMs), and treatment through Day Care Cancer Centers (DCCCs).
The Minister also updated Parliament on India's immunization program.
“As per the National Health Policy 2017 goals, the National Full Immunization Coverage has been maintained more than 90% for the last four years,” Patel said. National full immunization coverage was:

Meanwhile, recent data from the ICMR's National Cancer Registry Program (NCRP) show that India has recorded a significant decline in its cervical cancer burden.
According to the latest estimates, new cervical cancer cases have fallen by 37% over the past decade, declining from about 1.27 lakh cases annually to around 79,000, marking a major public health milestone in the fight against one of the country's most common cancers among women.
Unlike many other cancers, cervical cancer is considered highly preventable through HPV vaccination, regular screening, and timely treatment of precancerous lesions.
The WHO global targets for 2030 include vaccinating 90 percent of girls by age 15, screening 70 percent of women by ages 35 and 45, and ensuring 90 percent of women with pre-cancer and invasive cancer receive appropriate treatment.

Researchers at the Indian Institute of Technology (IIT) Kanpur have uncovered how an experimental vaccine booster molecule activates the body's immune system, a breakthrough that could help researchers develop safer and more effective vaccines in the future.
The study, published this month in the Proceedings of the National Academy of Sciences (PNAS), provides the first detailed structural view of how a synthetic molecule called EP67 binds to and activates an important immune receptor known as C5aR1. The findings offer researchers a molecular blueprint for improving vaccine adjuvants, the ingredients added to vaccines to strengthen and prolong immune protection.
Unlike vaccines, which train the immune system to recognize a specific pathogen, adjuvants help amplify the body's immune response, making vaccines more effective.

The researchers developed EP67 by taking inspiration from C5a, a naturally occurring immune protein released during bacterial and viral infections. While C5a helps activate immune cells to fight infections, prolonged activation can trigger harmful inflammation and damage healthy tissues.
To overcome this challenge, the IIT Kanpur team engineered EP67, a much smaller version consisting of just 10 amino acids.
The molecule retains the beneficial immune-stimulating properties of C5a while limiting the inflammatory effects. According to the researchers, EP67 selectively activates dendritic cells and macrophages, two immune cells that play a central role in generating long-lasting immunity, while largely avoiding activation of neutrophils, immune cells that are often responsible for excessive inflammatory responses.
This selective activation makes EP67 a promising candidate as a vaccine adjuvant capable of producing stronger immune protection without triggering inflammation.
Previous animal studies have shown the potential of EP67 in boosting vaccine responses.
When incorporated into experimental vaccines against multiple viruses, including SARS-CoV-2, the virus responsible for COVID-19, mice developed stronger immune responses than those receiving vaccines alone. Researchers also observed faster recovery in infected animals.
Beyond vaccines, EP67 has also shown promise against bacterial infections, including methicillin-resistant Staphylococcus aureus (MRSA), a major antibiotic-resistant pathogen.
However, the molecule has not yet entered clinical use in humans, and additional preclinical research will be required before human trials can begin.
Although scientists had previously observed EP67's immune-boosting effects, precisely how the molecule worked remained vague for a long time.
The IIT Kanpur researchers found that EP67 binds to C5aR1, a receptor located on the surface of immune cells. C5aR1 belongs to the large family of G protein-coupled receptors (GPCRs), which are involved in transmitting signals into cells and are among the most common targets for modern medicines.
Using cryo-electron microscopy (cryo-EM), the team captured near-atomic-resolution images showing EP67 adopting a hook-like shape that fits into the centre of the receptor, switching it on and initiating immune activation.
The structural insights have already enabled researchers to redesign EP67 by modifying its amino acid sequence to improve its stability and receptor binding. The next steps would be refining the formulation and introducing it in pre-clinical tests.

People living with Type 2 diabetes may be significantly more vulnerable to severe, potentially life-threatening complications from dengue, according to a new review by diabetes specialists.
The paper, presented in July 2026 and slated for publication in the International Journal of Diabetes & Technology (IJDT), also recommends combining dengue vaccination into routine diabetes care in dengue-endemic regions to better protect patients who are at high risk.
The review comes as many countries, including India, continue to witness surges in dengue cases during the monsoon months.

According to the researchers, chronic high blood sugar weakens the immune system and damages blood vessels, making it harder for the body to fight dengue infection.
It increases the risk of vascular leakage, severe bleeding, organ damage, and other complications associated with severe dengue.
The review notes that diabetes contributes to chronic inflammation, endothelial dysfunction, and impaired immune responses, all of which may worsen the course of dengue infection.
The researchers argue that dengue prevention should become part of routine diabetes management in countries where dengue is endemic. Lead author Dr. Jothydev Kesavadev, diabetologist, said, "People with Type 2 diabetes represent a particularly vulnerable group during dengue outbreaks.
Preventive strategies, including vaccination where appropriate, should become an integral part of diabetes care to reduce severe illness and deaths."
The review was co-authored by several diabetes specialists from across India, including Dr. Niti Pall, President-Elect of the International Diabetes Federation Europe.
It was presented during the 14th Jothydev's Professional Education Forum Annual Global Diabetes Convention in Kovalam, Kerala, and its publication was formally released by Kerala Health Minister K. Muraleedharan.

While the current paper is a review rather than a new clinical trial, it is supported by a growing body of evidence. A 2024 review published in Health Science Reports found that diabetes is significantly associated with severe dengue, death, elevated liver enzymes, and thrombocytopenia.
Similarly, a 2025 review in the International Health journal concluded that accumulating evidence increasingly supports diabetes as an important comorbidity contributing to poor dengue outcomes.

The findings come as India recently approved its first dengue vaccine, QDENGA (TAK-003). The vaccination should follow national guidelines and individual medical advice. Experts emphasize that vaccination complements, rather than replaces, mosquito bite prevention measures.
QDENGA (TAK-003) is a live-attenuated tetravalent dengue vaccine designed to protect against all four dengue virus serotypes.
It is administered as two 0.5 mL subcutaneous doses, given three months apart.
The vaccine is built on a DENV-2 backbone, incorporating structural proteins from DENV-1, DENV-3 and DENV-4 to provide broad immune protection.
The World Health Organization (WHO) recommends QDENGA for use in dengue-endemic settings without the need for pre-vaccination screening. The vaccine is also included in the WHO List of Prequalified Vaccines, allowing procurement through agencies such as UNICEF and PAHO.
Experts recommend that people with diabetes:
