Niti Aayog's Dr VK Paul on June 8 said that the provisional scientific date of the vaccine Biological E's Corbevax is very promising. “We should wait for the company (Biological E) to announce the price of their vaccine (Corbevax). It will depend on our negotiation with the company, under the new policy. The financial aid that has been given will meet part of the price.
