A nationwide ICMR analysis finds Covid vaccination lowers sudden death risk, while Covid hospitalisation, genetics, binge drinking, drug use and intense exercise increase odds among 18‑45-year-olds.
An Indian Council of Medical Research (ICMR) national study spanning October 2021 to March 2023 has linked severe Covid‑19 hospitalization, family history, and specific lifestyle factors to unexplained sudden deaths in adults aged 18–45, while clarifying that Covid vaccination actually lowers the risk.
Researchers analyzed 729 cases of sudden, unexplained death matched with 2,916 controls across 47 tertiary hospitals. Findings show individuals hospitalised with Covid-19 were nearly 4 times more likely to die suddenly; those with a family history of unexpected death had 2.5 times higher risk.
Additional factors increasing risk included binge drinking 48 hours prior (aOR ≈ 5.3), recreational drug use (~2.9), and vigorous exercise within two days (~3.7).
The study confirmed that vaccination is not a risk factor; instead a single dose reduced risk by 42%, and two doses by 49%.
The study emphasises the importance of targeted public-health messaging, recommending individuals with past severe Covid or family death history to avoid intense exertion for up to two years—a caution already highlighted by Health Minister Mansukh Mandaviya.
Experts and prior reports suggest sudden deaths in young, fit adults often stem from genetic heart conditions, lifestyle stresses like poor diet, alcohol, drugs, or overexertion—not vaccination.
