A new ICMR study has found that most Covid positive patients, who had received at least one vaccine dose before catching the infection, were infected by the Delta variant.
According to the ICMR study, most vaccinated individuals were infected by the Delta variant in India. ICMR is the first such analysis on breakthrough infections post-vaccination. But the death rate among vaccinated individuals was found to be very low and the clinical characterization was done on about 677 participants.
As per the reports, out of these 677 Covid positive participants, 71 had taken the Covaxin vaccine while the rest 604 had got the Covishield vaccine and two of the participants had also taken the Chinese Sinopharm vaccine. The report further informed that three death were reported among the vaccinated individual.
The ICMR study shows that the overall majority (86.09%) of the breakthrough infections were caused by the Delta variant (B.1.617.2). 9.8% of the positive Covid-19 cases required hospitalization while fatalities were observed in only 0.4% of the cases.
Further, the study has suggested that vaccination does provide a reduction in hospital admission and mortality. A total of 677 people had tested positive in the real-time RT-PCR tests done across North, South, West, East, Northeast and central parts of India. The samples were collected from 17 states and Union Territories. The 17 states are Maharashtra, Kerala, Gujarat, Uttarakhand, Karnataka, Manipur, Assam, Jammu and Kashmir, Chandigarh, Rajasthan, Madhya Pradesh, Punjab, Pondicherry, New Delhi, West Bengal and Tamil Nadu.
