Amid concerns over sudden deaths in Karnataka’s Hassan, Centre says no links with COVID-19 vaccines

In the wake of Karnataka Chief Minister Siddaramaiah linking heart-related deaths in Hassan district to COVID-19 vaccine, the Union Health Ministry on Wednesday (July 2, 2025) said extensive studies by ICMR and AIIMS have conclusively established no linkages between COVID-19 vaccines and sudden deaths.

Mr. Siddaramaiah on Tuesday (July 1, 2025) said “hasty approval and distribution" of the COVID-19 vaccine to the public could also be a reason for these deaths. He urged everyone to visit the nearest health centre immediately for a checkup if they have symptoms such as chest pain or difficulty breathing, and not to ignore these signs. The Union Health 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, preexisting conditions, and post-COVID-19 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.
