No linkages between Covid vaccine and heart-related deaths: Govt
Siddaramaiah had on Tuesday said 'hasty approval and distribution' of the Covid vaccine to the public could also be a reason for these deaths.
He urged everyone to visit the nearest health centre immediately for a check-up if they have symptoms such as chest pain or difficulty breathing, and not to ignore these signs.
The ministry said the matter of sudden unexplained deaths has been investigated through several agencies in the country and these studies have conclusively established that there is no direct link between COVID-19 vaccination and reports of sudden deaths.
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, it said.
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.
The 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 multi-centric 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, the statement said.
It looked at individuals who appeared to be healthy but died suddenly between October 2021 and March 2023.
The findings have conclusively showed that COVID-19 vaccination does not increase the risk of unexplained sudden deaths in young adults.
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, the statement said.
Importantly, no major changes in the pattern of causes have been observed when compared with previous years. In 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.
Together, these two studies offer a more comprehensive understanding of sudden unexplained deaths in young adults in India.
It has also been found 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, the statement said.
'Scientific experts have reiterated that statements linking Covid vaccination to sudden deaths are false and misleading, and are not supported by scientific consensus,' the statement said.
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, it said.
Such unfounded reports and claims could strongly contribute to vaccine hesitancy in the country, thereby adversely impacting public health.
The government remains committed to evidence-based public health research to protect the well-being of its citizens, the statement said.
The Karnataka chief minister had said more than 20 people have died due to heart attacks in the past month alone in just one district of Hassan.
'The government is taking this matter very seriously. To identify the exact cause of these series of deaths and to find solutions, a committee of experts has been formed under the leadership of Dr Ravindranath, Director of Jayadeva Institute of Cardiovascular Sciences and Research, and they have been instructed to submit a study report within 10 days,' he said in a post on X.

Hassan heart attack death cases: India's top drugmakers rally behind Covid vaccines
Leading drugmakers on Thursday rallied in support of Covid vaccines , using various social media platforms, amid a series of deaths in Karnataka's Hassan district due to heart attacks. Dilip Shanghvi, chairman and managing director at Sun Pharmaceuticals said in a post on LinkedIn, 'The deaths of multiple young individuals in one district of Karnataka due to cardiac ailments are unfortunate. While this appears to be specific to the district, linking it to the Covid-19 vaccine without any scientific evidence is "incorrect and misleading". "India's vaccine approval process is rigorous and science-driven, and we must continue to have confidence in it. The vaccine has been administered to millions across the country. If there were a connection, we would have seen similar incidents in many other places — which is not the case. The State health authorities should thoroughly investigate the situation to determine the cause,' Sanghavi said. Sorting to allay the apprehensions, Pankaj Patel, chairman, Zydus Lifesciences , which also manufactures Covid DNA vaccine, said in a post on X, 'There are other multiple reasons like age, environmental factors, genetics, lifestyle etc, that could be the leading cause of heart attacks in people. Several scientific studies globally and in India have conclusively shown that the risk of heart attack or myocarditis is greater after SARS-CoV-2 infection. #Vaccines save lives.' Appreciating the vaccination programme, Patel said, "the massive vaccination programme in our country during the peak of Covid phase saved millions of people and families. In fact a study published in Lancet estimated that India averted almost 3.4 million deaths due to vaccination in the year 2021," he said. Live Events Satish Reddy, chairman, Dr Reddy's Laboratories, wrote, 'India-made vaccines are by WHO and used worldwide. They helped end polio and fight Covid. At a time when India is seen as a vaccine leader, let's build trust in science, not doubt it. Public health must stay above politics.' A post on X attributed to Samir Mehta, executive chairman, Torrent Pharma said, 'India has earned global recognition as the Pharmacy of the World, supplying safe and effective vaccines to over 90 countries…Let's not allow misinformation to erode trust in science or the integrity of India's healthcare ecosystem.' Responding to rising concerns over the sudden deaths of more than 20 people in Hassan district, the Karnataka health department formed an expert committee to probe a possible link to Covid vaccines. However, support came pouring in for Covid vaccines. The Indian Vaccine Manufacturers Association said Covid-19 vaccines were developed and manufactured in the country with the highest safety and quality standards. Assuring about the safety of these vaccines, Dr/ G.V.J.A. Harshavardhan, director general at the association said the approvals were based on extensive evaluation in preclinical studies and human clinical trials with positive results on safety, efficacy, and immunogenicity of the vaccines. 'Patient safety and product quality are always prioritised during the vaccine development and its manufacture,' he said in a statement. He said prior to releasing the vaccines, they were tested extensively for safety by the manufacturers and are also provided batch release certification by the Central Drugs Laboratory (CDL) of the Ministry of Health and Family Welfare. Sudarshan Jain, secretary general, Indian Pharmaceutical Alliance (IPA) said during the pandemic, vaccines played a crucial role, and India consistently supplied medicines and vaccines across the world. "These vaccines have been well documented and rigorously tested as per regulatory processes. Misinformation and distortion of facts endanger public health and undermine the trust built on science and patient care globally".

AIIMS says no link between covid jabs and sudden deaths among young adults
Doctors at Delhi's All India Institute of Medical Sciences (AIIMS-Delhi) have refuted claims linking Covid-19 vaccines to sudden deaths in young adults in the country. This comes in the backdrop of recent claims by Karnataka Chief Minister Siddaramaiah stating that covid vaccines were linked to sudden deaths due to cardiac arrest among young adults in the state's Hassan district. The country's premier medical institution announced that its studies have found no such connection, instead attributing these tragic incidents primarily to lifestyle factors such as smoking, high blood pressure, and stress. Senior AIIMS doctors emphasized the crucial role these vaccines played in saving lives during the pandemic, noting that the studies are ongoing to determine the causes of sudden unexplained deaths. Researchers at AIIMS's pathology department are currently undertaking genomic studies to find the unexplained causes of death in approximately 25% of cases involving young individuals, where no apparent cause was initially identified. The pharmaceutical industry has also vouched for vaccine safety and debunked doubts over efficacy. Dr. Abhishek Yadav, additional professor in the department of forensic medicine at AIIMS, detailed two studies conducted by his department. A retrospective analysis from 2018 to 2022, comparing pre- and post-Covid data, found "no surge in the sudden cardiac deaths in the cases which were reported in the department". A second, ongoing study, initiated in 2023 in collaboration with the Indian Council of Medical Research (ICMR) and slated to continue for another year and a half, aims to gather more samples for scientifically validated results. This study has so far examined approximately 230 death cases, collecting family history, performing genomic and DNA level studies, and utilizing virtual autopsies. Dr. Yadav stated that this second study has also 'not found any link between covid vaccine and sudden deaths.' The research categorized cases into two age groups: 18-45 years and 45-65 years. Dr. Yadav said that coronary artery disease was identified as the most common historical factor, with over 50% of these cases linked to lifestyle factors and substance abuse, such as alcohol and smoking. The pathology department of AIIMS is continuing genomic studies on the remaining 25% of unexplained cases. Dr. Sudheer Arava, a professor in the department of pathology at AIIMS, explained that the study of 230 young individuals brought to the forensic department found heart attack to be the most common cause of death (50%), often linked to lifestyle risk indicators like high blood pressure, cholesterol, stress, and obesity. 'In 25% of cases, no identifiable cause of death was determined, and researchers are exploring potential molecular alterations. An interim report submitted to the ICMR indicates that nearly 50% of the deaths studied were due to heart attacks, with further research ongoing.' Dr. Sanjay Rai, professor at the department of community medicine at AIIMS, stated that the Covishield vaccine (developed by Oxford–AstraZeneca) showed an efficacy of 62.1%. He highlighted that various regulatory authorities have approved 37 different Covid-19 vaccines, with the World Health Organization (WHO) approving approximately 12, utilizing diverse technologies. For instance, Bharat Biotech's Covaxin uses a traditional technology, while Covishield and Russian Sputnik V are based on an adenovirus vector. Globally, over 13 billion vaccine doses have been administered, with countries like the United States completing fourth doses. The WHO now recommends vaccination for everyone aged six months and above, particularly with vaccines effective against newer variants. Dr. Karan Madan, associate professor in the department of pulmonary medicine, affirmed that Covid-19 vaccines were "highly effective and instrumental in lowering mortality rates during the pandemic". He emphasized their role as the "sole possible measure to save lives" at the time, providing "immense advantages" in preventing excess deaths. Dr. Madan also referenced a study on sudden cardiac deaths that found "no clear association" with vaccine usage. Sudarshan Jain, secretary general of the Indian Pharmaceutical Alliance (IPA), underscored India's role as a knowledge-driven sector, accounting for 60% of global vaccine production. He stated that Covid vaccines were "well documented and rigorously tested as per regulatory processes," warning that "misinformation and distortion of facts endanger public health and undermine the trust built on science and patient care globally". The Indian Vaccine Manufacturers Association also said that all Covid-19 vaccines in India received Emergency Use Authorization based on extensive preclinical and human clinical trial evaluations, showing positive results for safety, efficacy, and immunogenicity. Covid infections have been on a declining trend after showing a steady increase in the past few weeks. On Thursday, the country's active caseload dropped to 1,290 from 1,691 cases, with no deaths reported in the last 24 hours. The total number of Covid-19-related deaths this year stands at 146. The current spread is linked to Omicron sub-variants NB.1.8.1 and LF.7.

It's wrong to blame Covid jabs for cardiac arrests: Biocon chief Kiran Mazumdar-Shaw
Bengaluru: Days after chief minister Siddaramaiah blamed Covid-19 vaccines for the alarming rise in cardiac arrest cases among youngsters in the recent weeks, especially in Hassan district, Biocon chairperson Kiran Mazumdar-Shaw said Thursday his comments were "factually incorrect" and would contribute to "public misinformation". With close to 25 deaths due to cardiac arrests in Hassan alone in the last 40 days, Siddaramaiah said on Tuesday the "hasty approval and distribution of Covid vaccines" could also be a reason for the fatalities. Mazumdar-Shaw, however, wrote on X: "Covid-19 vaccines developed in India were approved under the emergency use authorisation framework, following rigorous protocols aligned with the global standards for safety and efficacy." You Can Also Check: Bengaluru AQI | Weather in Bengaluru | Bank Holidays in Bengaluru | Public Holidays in Bengaluru Responding to the CM's comment, she said, "To suggest that these vaccines were hastily approved is factually incorrect and contributes to public misinformation." Mazumdar-Shaw added, "These vaccines have saved millions of lives and, like all vaccines, may cause side effects in a very small number of individuals. It is important to acknowledge the science and data-driven processes behind their development, rather than engage in retrospective blame." As the cardiac arrest-linked casualties in Hassan district snowballed into a major controversy, the CM commented, "The state govt has taken the matter seriously and an expert committee has been constituted under the chairmanship of Dr Ravindranath, director of Jayadeva Institute of Cardiovascular Sciences and Research, to ascertain the exact cause of these deaths and to find solutions. The committee has been instructed to submit a report within 10 days. " The same committee in Feb 2025 was also tasked with conducting a thorough study on reasons behind sudden deaths of youngsters in Karnataka and exploring whether these fatalities were triggered by the Covid vaccines. Mazumdar-Shaw commented, "Heart attacks being linked to Covid vaccines even after four years does not stack up. There are many other reasons, including performance-enhancing drugs, excessive exercise routines, etc. "
