India has become the first country in the world to administer a DNA vaccine against COVID-19. The ZyCoV-D which is the World’s first plasmid DNA vaccine has been produced by Ahmedabad-based vaccine manufacturer Zydus Cadila and it was administered for the first time in Patna. It is a Painless and Needleless vaccine given at intervals of 28 days and 56 days. It is the second India-made vaccine to get emergency authorization in India after Bharat Biotech’s Covaxin.
The Indian government approved emergency use authorisation for Zydus Cadila’s DNA vaccine earlier this year, citing initial results from Phase III clinical trials that showed approximately 66 per cent efficacy for symptomatic cases.
