The Central government has sufficient financial resources available to procure at least 400-500 million doses of Covid-19 vaccine, said Rajesh Bhushan, Union Health Secretary on Tuesday. Responding to a query about Covid procurement by next year, Bhushan informed that various countries in the world have explored different options for extending financial support. “The first one is — advanced market commitments by different countries. The second one is — providing financial help to vaccine manufacturers in terms of conducting their Research & Development (R&D). This financial support may not come directly from the government but from financial institutions. These are some of the international models,” he said.
