A retrospective cohort study on the impact of vaccination among Covid-19 patients by Star Health and Allied Insurance unveiled the significant impacts of vaccination among individuals 45 years and above. The study concluded that there was a marked reduction in the total hospitalisation expenses by approximately 24 per cent, the Average Length of Stay (ALOS) by a mean of 2.1 days, ICU requirement by 66 per cent and a reduction of approximately 81 per cent in mortality among patients who had completed two doses of vaccination.
