Cardiologist Debunks Myths Linking COVID-19 Vaccines to Heart Attacks
News Mania Desk / Piyal Chatterjee / 11th August 2025
A senior cardiologist has dismissed widespread misinformation suggesting that COVID-19 vaccines cause heart attacks due to harmful ingredients such as mercury. The doctor criticised such claims as “nonsense,” stressing that the vaccines are safe and have no such toxic additives.
The remarks come amid lingering public concerns over a perceived rise in heart attack cases since the pandemic, with some attributing it to vaccination drives. The cardiologist clarified that while rare side effects like myocarditis and pericarditis have been reported, particularly in younger males after mRNA vaccines, these cases are generally mild, treatable, and far outweighed by the benefits of immunisation.
Multiple global and Indian studies have found no credible link between COVID-19 vaccination and a surge in heart attack cases. In Karnataka’s Hassan district, where a spate of cardiac deaths prompted public alarm, investigations by the Indian Council of Medical Research (ICMR) and AIIMS ruled out any causal association with vaccines. Instead, experts cited lifestyle factors, pre-existing heart disease, stress, and pollution as more plausible contributors.
Health authorities, including the World Health Organization, have consistently emphasised that COVID-19 infection itself poses a far greater risk to the heart, significantly increasing the likelihood of myocarditis, heart attacks, strokes, and other complications. Vaccination, they note, helps reduce these risks by preventing severe illness.
The cardiologist urged the public to rely on verified medical guidance rather than circulating unsubstantiated claims on social media. “The focus should be on controlling actual risk factors like poor diet, inactivity, smoking, and untreated hypertension, rather than blaming life-saving vaccines,” he said.
Medical experts reiterate that widespread vaccination remains a cornerstone of pandemic response, safeguarding not just against COVID-19, but also against the virus’s long-term cardiac impact.
