At least one dose of vaccine prior to COVID-19 infection provided 60% protection against post-discharge mortality, an Indian Council of Medical Research (ICMR) study on factors related to mortality within one year after discharge in hospitalised COVID-19 patients has found.
The study has also found that there is a higher chance of mortality within one year following discharge for those over 40 years of age, those with comorbidities, and those who suffered moderate to severe COVID.
The study observed that of the 14,419 participants contacted at least once in one year after discharge from hospital, 942 deaths or 6.5% all cause mortality was reported.
