Covid vaccines reduced risk of sudden death in young adults, study finds

A comprehensive study by the Indian Council of Medical Research (ICMR) has concluded that COVID-19 vaccination does not increase the risk of unexplained sudden deaths among young adults in India. On the contrary, the study suggests that receiving at least one dose of the vaccine may actually reduce the likelihood of such fatalities.

The research, which spanned from October 1, 2021, to March 31, 2023, involved 47 tertiary care hospitals across the country and focused on people aged 18-45 years who were apparently healthy with no known comorbidities and died suddenly from unexplained causes. The analysis included 729 cases and 2,916 controls, revealing that those who had received two doses of the vaccine had lower odds of experiencing unexplained sudden death, while a single dose did not have the same protective effect.

However, the study identified several factors that increased the risk of sudden death. These include a history of hospitalization due to Covid-19, a family history of sudden death, binge drinking within 48 hours prior to death, the use of recreational drugs or substances, and engaging in vigorous-intensity physical activity within 48 hours before death.

Union Health Minister Mansukh Mandaviya had earlier cited the findings of the ICMR study, particularly cautioning those with a past history of severe Covid-19 infection against overexertion. His advice came in response to inquiries about a series of deaths reported in Gujarat during Navratri celebrations.

The ICMR's investigation has provided crucial insights into the factors contributing to sudden deaths among young adults, ruling out any connection between COVID-19 vaccination and such incidents. Instead, it points to other health and lifestyle factors as playing a more significant role in these unexpected events.
