No link between Covid vaccine, deaths: Centre
'Studies by the Indian Council of Medical Research (ICMR) and National Centre for Disease Control (NCDC) affirm that COVID-19 vaccines in India are safe and effective, with extremely rare instances of serious side effects. Sudden cardiac deaths can result from a wide range of factors, including genetics, lifestyle, pre-existing conditions, and post-COVID complications,' read the health ministry statement.
On Tuesday, Karnataka chief minister Siddaramaiah alleged that the hastily approved and distributed Covid vaccines could also be a reason for sudden deaths. In a post on X, he wrote that more than 20 people had died of heart attacks in the past one month alone in the Hassan district of the state.
ICMR and NCDC have been working together to understand the causes behind sudden unexplained deaths, especially in young adults between the ages of 18 and 45 years. To explore this, two complementary studies were undertaken using different research approaches—one based on past data and another involving real-time investigation.
The first study, conducted by ICMR's National Institute of Epidemiology (NIE), was titled 'Factors associated with unexplained sudden deaths among adults aged 18-45 years in India – A multicentric matched case–control study.' This study was carried out from May to August 2023 across 47 tertiary care hospitals in 19 states and Union Territories. It looked at individuals who appeared to be healthy but died suddenly between October 2021 and March 2023. The findings have conclusively shown that COVID-19 vaccination does not increase the risk of unexplained sudden death in young adults, said the health ministry.
The second study, titled 'Establishing the cause in sudden unexplained deaths in young,' is currently being conducted by the All India Institute of Medical Sciences (AIIMS), New Delhi with funding and in collaboration with ICMR. This is a prospective study aimed at determining the common causes of sudden deaths in young adults. Early analysis of data from the study indicates that heart attacks, or myocardial infarction (MI), continue to be the leading cause of sudden death in this age group. Importantly, no major changes in the pattern of causes have been observed when compared with previous years. In the majority of the unexplained death cases, genetic mutations have been identified as a possible cause of these deaths. The final results will be shared once the study is complete, said the statement.
'Together, these two studies offer a more comprehensive understanding of sudden unexplained deaths in young adults in India. It has also been revealed that COVID-19 vaccination does not appear to increase the risk, whereas, the role of underlying health issues, genetic predisposition and risky lifestyle choices does play a role in unexplained sudden deaths.'
Scientific experts have reiterated that statements linking Covid vaccination to sudden deaths are false and misleading, and are not supported by scientific consensus. Speculative claims without conclusive evidence risk undermining public confidence in vaccines, which have played a crucial role in saving millions of lives during the pandemic.
'Such unfounded reports and claims could strongly contribute to vaccine hesitancy in the country, thereby adversely impacting public health. The Government of India remains committed to evidence-based public health research to protect the well-being of its citizens,' read the statement.

New COVID variant Stratus (XFG) spreads in the US: Symptoms, risks, and what you need to know
As the United States experiences another wave of COVID-19, a variant named Stratus (XFG) has caught the attention of health authorities. Officially identified as XFG, this recombinant strain was first detected in Southeast Asia in January 2025. While initially flying under the radar in the US, XFG accounted for 14% of all cases by late June, making it the third most prevalent variant according to the Centers for Disease Control and Prevention (CDC). Globally, the World Health Organization ( WHO ) has added XFG to its monitoring list, though it continues to classify the variant's overall public health risk as low. Experts reassure that current COVID-19 vaccines remain effective against symptomatic and severe disease caused by this strain. What is the new covid variant in the US Stratus (XFG) and how is it different XFG is a recombinant variant, meaning it combines genetic material from two earlier strains: F.7 and LP.8.1.2. While LP.8.1.2 is now the second most common strain in the US, XFG is notable for its mutations that may help it evade the immune system. Importantly, experts emphasize that these mutations do not make XFG more dangerous. According to Dr. Subhash Verma, microbiology and immunology professor at the University of Nevada, XFG does not cause more severe illness or different symptoms compared to earlier Omicron variants. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Use an AI Writing Tool That Actually Understands Your Voice Grammarly Install Now Undo Health authorities classify the variant as low risk, but continued monitoring is essential to track its evolution. How fast is this covid variant As reported by USA Today, XFG's prevalence in the US has increased rapidly in recent months: March 2025: 0% of cases April 2025: 2% of cases May 2025: 6% of cases Late June 2025: 14% of cases Globally, the WHO reported a rise from 7.4% in early May to 22.7% by the end of June across 38 countries. Despite this growth, XFG has not surpassed the top two variants, but its upward trend underscores the importance of ongoing genomic surveillance and vaccine coverage. Symptoms of Stratus (XFG) variant As USA Today reported, know the familiar COVID-19 symptoms for XFG infections. These include: Fever or chills Cough Fatigue Sore throat Loss of taste or smell Nasal congestion Muscle aches Shortness of breath Headache Nausea or vomiting Health officials stress that symptom patterns remain consistent with prior Omicron variants, and early testing, vaccination, and isolation are key to controlling spread. Prevention tips for Stratus (XFG) variant To reduce the risk of infection from the XFG variant (Stratus), follow these recommended safety measures: Stay up to date with COVID-19 vaccines: Ensure primary doses and booster shots are current, as vaccines remain effective against severe disease. Practice good hygiene: Regular handwashing, using hand sanitizer, and avoiding touching the face can reduce transmission. Wear masks in crowded or enclosed spaces: Especially in public transport, healthcare facilities, or areas with high case counts. Maintain physical distancing: Avoid close contact with people showing respiratory symptoms. Monitor symptoms and test early: Get tested if you experience fever, cough, fatigue, or other COVID-related symptoms. Isolate if infected: Follow local health guidelines to prevent spreading the virus to others. Ventilate indoor spaces: Increase airflow in homes, offices, and public spaces to reduce viral concentration.

ICMR study flags unregulated herbal tobacco products on e-commerce sites
A new study has found that herbal cigarettes, often marketed as 'safer alternatives,' produce harmful combustion products that are similar to those found in tobacco cigarettes. The affordability and digital accessibility of these products, combined with misleading health claims, pose significant risks to tobacco users seeking genuine cessation support, said researchers from Indian Council of Medical Research (ICMR)-National Institute of Cancer Prevention and Research. Dr Prashant Kumar Singh, lead author and scientist, ICMR-National Institute of Cancer Prevention and Research, said that their study, published in the journal Tobacco Control, found at least 316 unverified herbal products targeting tobacco users across major Indian e-commerce platforms. 'Herbal tobacco cessation products (HTCPs), marketed with claims to support tobacco or nicotine cessation, are increasingly sold online in low and middle-income countries. However, there is little regulatory oversight or evidence on their safety and effectiveness. This study assessed the availability, affordability, claims and regulation of HTCPs on Indian e-commerce platforms,' Dr Singh told The Indian Express. In India, as per the report, there are approximately 266.8 million users of tobacco, the majority of whom consume smokeless tobacco products. Despite substantial progress in tobacco control, the reach of cessation services remains uneven across different population groups. According to the study authors, recent studies indicate that HTCPs are increasingly being used by young adults and the regulatory landscape for these products remains fragmented. HTCPs encompass a broad category of formulations—including herbal capsules, lozenges, gutkha substitutes, powders and herbal smokes—claimed as natural, safer alternatives to conventional pharmacotherapy. According to Dr Singh, these products are increasingly available on digital platforms, where vendors often make therapeutic claims such as 'eliminates cravings,' 'detoxifies lungs,' or 'replaces gutkha safely'. Researchers searched some of the major Indian e-commerce platforms, screened product listings and categorised product type, claimed indications, presence of disclaimers, regulatory approvals and pricing. 'We were able to identify 316 unique HTCPs across some of the major Indian e-commerce platforms,' he said. The study showed that HTCPs were marketed in three primary formulations: combustible products (42.7 per cent), raw herbal preparations (34.5 per cent) and other formats such as gummies, drops, capsules and patches (22.8 per cent). Products featured diverse flavours and varied widely in pricing. 'Our verification of regulatory claims through official databases adds credibility to the findings,' Dr Singh said. According to the study findings, only 23 per cent of products with AYUSH claims and 15 per cent with Central Drugs Standard Control Organisation (CDSCO) claims could be verified through official databases. Of the 316 HTCPs, 197 (62.3 per cent) reported at least one form of certification claim. Additionally, 43.7 per cent of products promoted ancillary health claims such as detoxification or anxiety relief. Only 12 of the products displayed age restrictions, and none had functional age verification mechanisms. A small fraction (0.5 per cent) referenced World Health Organization (WHO) affiliation, raising concerns about potentially misleading endorsements. The authors urged e-commerce platforms to implement mandatory health claims verification and functional age-restriction protocols. They added that all products must undergo testing in accredited facilities, such as the National Tobacco Testing Laboratories.

What your cough says about your health: Spot the difference between dry, wet, and wheezing
Coughing is more than a minor annoyance; it can reveal important clues about your health. According to a study published in PLOS One, understanding whether your cough is dry, wet, or wheezing helps identify its cause, from viral or bacterial infections to asthma or lingering post-infection irritation. A dry cough is often persistent and hacking, while wet coughs produce mucus, and wheezing signals potential breathing difficulties. Recognising these differences can guide treatment choices, self-care, and when to seek medical attention. By learning what your cough says about your body, you can act early, protect your lungs, and prevent serious complications. Different types of cough : How to spot viral, bacterial, and lingering coughs Viral cough A viral cough is typically dry, persistent, and sometimes painful. It often comes on suddenly and is caused by viral infections such as the flu, the common cold, or COVID-19. Unlike bacterial infections, a viral cough usually doesn't produce thick mucus. Cough suppressants may provide relief, but expectorants, medications that help clear mucus, are generally ineffective in this case. While uncomfortable, viral coughs often resolve on their own within a week or two. Bacterial cough A bacterial cough is generally wetter, producing yellow or green mucus. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Benefits of Trading Bitcoin CFDs IC Markets Learn More This type of cough can signal bacterial infections like bronchitis or pneumonia. If left untreated, it can escalate to serious complications. Antibiotics are typically required to tackle the underlying infection, while expectorants and adequate hydration can ease symptoms. The colour of the mucus is an important clue: yellow or green usually indicates bacteria, whereas clear mucus points toward a viral cause. Whooping cough Whooping cough, or pertussis, is a severe bacterial infection caused by Bordetella pertussis. It is marked by intense coughing fits followed by a high-pitched 'whoop' when inhaling. This condition can be particularly dangerous for infants and young children, so prompt medical treatment is crucial. Vaccination remains the most effective preventive measure, but early intervention with antibiotics is essential for those infected. Post-infection cough Sometimes, coughing persists long after the initial infection has cleared. This post-infection cough can be phlegmy and lingering, especially in smokers or people with underlying lung conditions. Though usually not dangerous, it can be disruptive and may even become chronic in some cases. Remedies like herbal teas, steam inhalation, and gentle expectorants can provide temporary relief while the airways fully recover. Not all coughs need immediate medical attention, but certain warning signs should not be ignored. If your cough persists for more than a few weeks, produces thick yellow or green mucus, or is accompanied by fever, chest pain, or difficulty breathing, consult a healthcare professional. Prompt evaluation can help prevent serious complications and ensure appropriate treatment. Wet vs. dry cough: How to tell the difference A simple way to differentiate coughs is by checking for mucus. Wet coughs produce mucus or phlegm and are often linked to infections in the lungs or airways. Dry coughs, on the other hand, don't produce mucus and are commonly associated with viral infections, allergies, or irritants like smoke and dust. Understanding this distinction can guide treatment choices and self-care measures. Mucus colour and what it reveals about your cough The colour of your mucus can provide additional clues about the cause of your cough. Clear or white mucus usually points to viral infections or mild irritation, while yellow or green mucus suggests a bacterial infection that may require antibiotics. Monitoring changes in mucus colour and consistency can help you track the progression of your illness and decide when to seek medical help. Wheezing and asthma: When coughing signals a serious issue A wheezing cough, a high-pitched, whistling sound during breathing, can indicate asthma or other bronchial conditions. Asthma-related coughing may be triggered by allergens, exercise, or respiratory infections. If wheezing is frequent or accompanied by shortness of breath, it's important to see a doctor for diagnosis and treatment. Asthma medications, including inhalers, can manage symptoms and prevent severe breathing difficulties. While most coughs resolve on their own, ignoring persistent symptoms can be dangerous. Bacterial infections can progress to pneumonia, while untreated asthma may lead to severe respiratory complications. Chronic coughing can also strain the chest muscles, disrupt sleep, and reduce overall quality of life. Recognising the underlying cause early helps prevent these complications and ensures proper care. Treatment depends on the type of cough and its cause. Dry coughs may respond well to cough suppressants, while wet coughs benefit from expectorants, staying hydrated, and resting the lungs. For asthma-related coughs, inhalers and other prescribed medications are essential. Supportive care, such as warm fluids, humidified air, and avoiding irritants like smoke, can also help alleviate symptoms.
