Mahima Datla, the MD of Biological E -- whose vaccine Corbevax was launched today for 12-to 14-year-olds in the country -- today indicated that the affordability of her vaccine was one of the key goals they worked for. The Corbevax has been made available to the government at a cost of Rs. 145 and Rs. 10 as taxes -- the lowest in the world. Calling it the "most affordable" vaccine, Ms Datla told NDTV today that the firm "needed to keep affordability at the centre of this".
