A recent study by researchers from Hyderabad-based Centre for Cellular and Molecular Biology (CCMB) and AIG (Asian Institute of Gastroenterology) Hospitals found that the severity of the COVID-19 disease among people infected with the Delta variant of coronavirus was significantly lower among vaccinated individuals.

“Severity of the disease (3.2% Vs 7.2%) and requirement of ventilatory support (2.8% Vs 5.9%) were significantly low in the vaccinated group despite the fact that these individuals had significantly higher age and risk factors,” the study said.

The rate of mortality was found to be about 50% lower in fully vaccinated individuals having a breakthrough infection (despite completing 14 days after the second dose). Preliminary results suggest that both Covishield and Covaxin have comparable efficacies in reducing the severity (ICU requirement at the time of admission) and mortality among patients infected with the Delta variant, the study said.
