"Pricing is perhaps complex because some of them (candidate vaccines) are at an early stage (of development). This information will be refined as we move along. There is no firm information. But we have asked about the price range (of the potential vaccines) from individual manufacturers," NITI Aayog member VK Paul said.

According to reports, there are 182 vaccine candidates globally in pre-clinical or clinical trials. Of these, 36 are in clinical trials and nine in final states of human trials.

In India, there are at least eight candidates being developed, two of which have entered phase II trials. But what are the vaccines that can be made available in India and at what price will they be offered?
