Currently, the country is using two 'made-in India' jabs -- Covishield and Covaxin -- to inoculate its billion-plus population and has administered 20 crore doses since launching the world's largest vaccination drive in mid-January. A third vaccine, Russian-made Sputnik V, has been approved by the government and is being used on a smaller scale at present.

The aim of the mission is to accelerate the development of at least six vaccine candidates and ensure that they are licenced and introduced in market for emergency use at the earliest.
