Covishield generated 93% protection against Covid, whereas mortality due to the infection came down by 98% during the second wave which was driven by Delta variant, officials said citing a vaccine effectiveness study conducted by Armed Forces Medical College (AFMC).

The study was conducted on 15 lakh doctors and frontline workers in AFMC who were administered with Covishield. “Protection to the extent of 93% was seen and this was during the second wave which was driven by the Delta variant also 98% mortality reduction was seen,” Niti Aayog member, health, Dr V K Paul said underlining the role of vaccination to protect against death as well as infection.

He, however, also highlighted the need to follow Covid-appropriate behaviour as no vaccine alone can guarantee protection against the infection. “No vaccine guarantees that infection will not happen but serious disease gets prevented and nearly eliminated,” he said.

Underlining that all vaccines available in India are effective against Delta variant, officials said the Indian Council of Medical Research is also studying their effectiveness against the Delta Plus variant and results are being analysed and will be shared soon.
