This statement follows the release of major studies led by ICMR and Aiims which concluded that Covid-19 vaccines do not cause sudden deaths in adults.
'No link between vaccines and cardiac deaths'
The Ministry of Health and Family Welfare (MoHFW) said multiple agencies investigated the phenomenon of sudden, unexplained deaths across India. The results confirmed no direct causal relationship between these deaths and Covid-19 vaccines.
'Sudden cardiac deaths can result from a wide range of factors, including genetics, lifestyle, pre-existing conditions, and post-Covid complications,' the ministry said in a statement.
One of the key investigations, conducted by ICMR's National Institute of Epidemiology, surveyed 47 hospitals between May and August 2023. Titled 'Factors associated with unexplained sudden deaths among adults aged 18-45 years in India', the study concluded that Covid-19 vaccination does not raise the risk of sudden unexplained death among young adults.
An Aiims-ICMR study 'Establishing the cause in sudden unexplained deaths in young', suggested that most such fatalities were attributable to heart attacks, genetic predispositions, and poor lifestyle habits.
Vaccines critical to public health, says govt
Reaffirming the safety profile of vaccines, MoHFW said that data from ICMR and the National Centre for Disease Control show only rare instances of adverse effects. The ministry warned against misinformation that could fuel vaccine hesitancy. 'Statements linking Covid vaccination to sudden deaths are false and misleading,' it said. 'Speculative claims without conclusive evidence undermine public confidence in life-saving immunisation.'
MoHFW said that Covid-19 vaccines were instrumental in saving millions of lives and continue to be vital in protecting against severe illness.

Holistic approach to type-2 diabetes management and the role of lifestyle factors
As a country, we are dining out and ordering in like never before. Convenience aside, the salty snacks and sugary desserts that get delivered to our doorstep in less than 30 minutes, come with consequences. Sheela Krishnaswamy, Wellness & Nutrition Consultant shares that an exhaustive, decade-long study published in Lancet in 2023, found that 101 million people in India are living with diabetes and another 136 million people could be living with pre-diabetes. Some people in India are genetically predisposed to developing type 2 diabetes, which is exacerbated by lifestyle factors including lack of exercise and eating an unhealthy diet. Healthy dietary habits, maintaining a healthy weight, and getting adequate exercise, are some of the factors that can help to prevent type 2 diabetes. In most people with Type 2 diabetes, the pancreas does not produce enough insulin (a hormone critical for transporting blood sugar into cells) and cells respond poorly to insulin and take in less sugar (insulin resistance). Eating a healthy diet is an important strategy to prevent and manage type 2 diabetes. Even small changes in dietary habits can lead to significant, long-term health benefits. In India, eating almonds every day has been a time-honoured tradition. The wisdom of this practice is supported by a wealth of recent scientific studies. The latest Dietary Guidelines released by the ICMR-NIN, recommended the regular consumption of nuts like almonds as part of a balanced diet. Almonds are recognized not only as an excellent source of natural plant-based protein but also as a nutritious, healthy snack that contributes to overall well-being. Two studie s by the National Diabetes, Obesity, and Cholesterol Foundation (NDOC), designed to ascertain the impact of simple changes to an individual's diet, found that consumption of 20 grams of almonds before each major meal benefited blood sugar control both in the short-term (over three days) and in the long term (over three months) among Asian Indians with overweight/obesity and prediabetes. The three-month intervention reversed prediabetes in nearly one-quarter of the participants. The study results must be viewed in the context of the overwhelming array of associated risks and complications—heart attack, stroke, kidney damage, limb amputation, blindness, and nerve damage—that diabetes brings with it. More than 60% of people with pre-diabetes are likely to convert to diabetes in a span of five years. Moreover, 50% of people are unaware of their diabetic status, further increasing chances of these complications. There's yet another pertinent reason for caution. Asian Indians—characterized by tendency for abdominal adiposity, higher waist circumference, lower BMI, and greater insulin resistance—are more prone to developing diabetes. It is also well documented that obesity increases diabetes risk. A seminal study conducted on overweight and obese Asian Indian adults found that eating 43 grams of almonds daily for 12 weeks reduced insulin resistance, improved insulin sensitivity, and helped control blood glucose levels. The people eating almonds achieved significant reductions in body weight, body mass index (BMI), and waist circumference over the intervention period and lowered their total cholesterol. Overtime, these changes could reduce the risk of diabetes and other cardiometabolic diseases. Rich in natural sources of some of the essential nutrients, almonds are a smart and satisfying food not only for blood glucose control but also to boost intake of key nutrients. A typical 28 grams serving has 13 grams of unsaturated fat and just 1 gram of saturated fat. They make for a good snacking choice as they are also a rich and natural source of plant protein, dietary fiber, monounsaturated (good) fat, Vitamin E, magnesium, and phosphorus. Their daily consumption is known to decrease the intake of carbohydrate calories and even help in lowering the blood sugar impact of carbohydrate foods, which affects fasting insulin levels.

Tech meets touch: How doctors are adapting to the digital transformation of healthcare
As AI, telemedicine and digital tools transform healthcare, doctors are adapting to a tech-driven future while preserving the human touch. Experts say technology can enhance care but empathy, intuition and doctor-patient relationships remain essential in modern medicine's evolving role. read more As technology continues to transform healthcare at an unprecedented pace, doctors are learning to walk the tightrope between innovation and intuition. From AI-powered diagnostics to telemedicine platforms and wearable tech, physicians across India are adopting new tools with cautious optimism but insist that the irreplaceable human touch remains at the core of healing. Dr. Ajay Agarwal, Senior Director of Internal Medicine at Fortis Hospital (Noida) believes that while digital innovation brings undeniable efficiency, it must be grounded in clinical wisdom. 'We must navigate this transformation with a blend of cautious optimism and evolving pragmatism,' he said. Telemedicine for instance, has become a permanent fixture in healthcare practice, especially for chronic disease follow-ups and preliminary triage. STORY CONTINUES BELOW THIS AD 'It has enhanced accessibility and allowed us to manage patients remotely with greater ease,' Dr. Agarwal added. 'But subtle diagnostic cues like a patient's gait, expressions or behavioural signs—are still best read in person.' AI, meanwhile, is viewed by Dr. Agarwal as a powerful assistant rather than a replacement. 'It opens doors to deeper clinical reasoning by highlighting imaging patterns and supporting diagnosis, but its integration must be critically evaluated by trained physicians,' he said. Digital health portals and patient records available online have also improved data sharing across hospitals, bridging long-standing communication gaps. Still, he added, 'The art of understanding the person behind the illness, that is something no tool can replicate.' Dr. Tushar Tayal, Consultant in Internal Medicine at CK Birla Hospital (Gurugram) echoed this sentiment, saying that technology has permanently altered the landscape of healthcare. 'The COVID-19 pandemic accelerated a shift that was already underway,' he says. Telemedicine has evolved from a peripheral service to a mainstay of patient care, particularly useful for mental health, routine follow-ups and care in underserved regions. 'Doctors have had to develop virtual bedside manners—learning how to maintain empathy and build trust through a screen.' AI's role in diagnostics is particularly pronounced in radiology, pathology, and dermatology, where pattern recognition can be enhanced by machine learning. 'These tools help reduce errors and allow us to focus more on patient interaction,' Dr. Tayal added. STORY CONTINUES BELOW THIS AD Wearables and mobile health apps are another frontier. Devices that monitor heart rate, blood sugar, and sleep patterns now offer real-time data that can inform personalised treatment plans. 'Doctors are collaborating with data scientists to make sense of this information,' he said. Medical education is also adapting, with new training modules focusing on digital ethics, AI tools and critical data analysis. Still, the integration of tech in healthcare isn't without its challenges. Data privacy, screen fatigue and the risk of over-reliance on algorithms remain key concerns. Yet both doctors agree that rather than replacing physicians, technology is expanding their role. Today's doctors are no longer just healers, they are digital guides, interpreters of complex data and managers of virtual care ecosystems.

Covid Vaccines Not Behind Sudden Deaths, Suggests Top Medical Body Study
New Delhi: None of the Covid vaccine doses are linked to heart attacks and deaths, said Dr Sudheer Arava from AIIMS, who is part of the research currently underway by the Indian Council of Medical Research (ICMR) and the All India Institute of Medical Sciences (AIIMS). Speaking to IANS, he noted that preliminary data so far has shown no indication between heart attack and Covid jabs, developed in the country. "Till now, our study data says that the vaccine has no effect on the cause of death, whether it is a first dose, second dose or third dose, there is no difference in it," Arava added. His comments amid concerns over several heart attack deaths being seen in the country. About the study, Arava, from AIIMS' Department of Pathology, said that it was launched by the ICMR, in the aftermath of deaths happening in the country after the arrival of Covid. Initial results, soon to be published, indicate that 50 per cent of the deaths caused among individuals between 18 to 45 years are due to heart attacks. The other finding is "unexplained death, in which we could not ascertain the cause". Further, to understand whether the deaths match with those during pre-COVID days, they analysed previous data but found no difference in the cause of death. "We found out that the pattern of death rate among young individuals in pre-COVID times is similar to that of during COVID. We did not find any effect of the vaccine in this... There is no clear-cut indication saying that the vaccine causes sudden death in young individuals," Arava told IANS. "The benefits of vaccines far outweigh the very small possible side effects," added Dr Rajiv Narang from the Department of Cardiology, AIIMS. He added that "people should be aware that a heart attack is not a simple issue -- there can be many causes for sudden cardiac arrest". Meanwhile, the Indian Vaccine Manufacturers Association (IVMA) also issued a statement assuring the safety of the Covid vaccines developed in the country. "Covid-19 vaccines of India were developed and manufactured with the highest safety and quality standards," IVMA Director General, Dr G.V.J.A. Harshavardhan, said. "All Covid-19 vaccines in India were approved for Emergency Use Authorisation (restricted use in emergency situations of the WHO guidelines)," he added. Harshavardhan noted that the approvals were based on extensive evaluation in preclinical studies and human clinical trials. He stated that the Indian vaccines not only helped "control the Covid-19 pandemic and restrict its impact on lives, livelihoods, but most importantly, enabling India's economic activity and GDP to rebound and grow to new heights globally". Harshavardhan said that the benefits of India-made Covid jabs were also extended to several countries worldwide, under the government's Vaccine Maitri programme. "We hereby reassure the public on the safety and efficacy of Covid-19 vaccines," he said.
