The Gujarat-based company will use a particular design known as the Tropis, which gained authorization from European regulators in 2017. ZyCoV-D will follow as the fifth vaccine approved for use in the nation. It will become the first DNA vaccination approved globally in any nation. Additionally, the company provided data analyzing a two-dose schedule for the shot. The SEC will compare the data before deciding whether to move forward.
