NEW DELHI: A group study on the impact of vaccination among Covid-19 patients by Star Health and Allied Insurance has unveiled the significant impacts of vaccination among individuals 45 years and above. The study has concluded that there was a marked reduction in the total hospitalization expenses by more or less 24 percent, the average length of stay by a mean of 2.1 days, ICU requirement by 66 percent and a reduction of approximately 81 percent in mortality among patients who had completed two doses of vaccination. The report said the study was conducted during the second wave (March and April 2021) and considered a sample size of 3,820 hospitalised patients from across India who were 45 years and above. The study revealed that the average cost of hospitalisation of the unvaccinated group was Rs 2.77 lakh while the vaccinated group recorded an average cost of Rs 2.1 lakh. The cost reduction was due to factors like reduced need of ICU requirement and reduction in the length of hospital stay from an average of seven days among unvaccinated to an average of 4.9 days for the vaccinated group, the report said. Star Health believes that the only way to mitigate a third wave is to increase vaccination among the population, host active demystification programs and campaigns through community engagement to reach rural and urban population alike.
