The government is pinning its hopes for mass supply on Serum Institute, which lodged the first formal application for emergency-use approval of AstraZeneca's shot on Monday.

Chief Executive Officer Adar Poonawalla had earlier said the vaccine would be priced at 1,000 rupees ($13.55) per dose in India's private market, but governments signing large supply deals would likely buy it at lower prices.

Poonawalla had said Serum will first focus on supplying the vaccine to Indians before distributing it to other countries.

With 9.70 million COVID-19 cases recorded so far, India is second only to the United States and is accelerating its review of vaccines developed by Pfizer Inc and AstraZeneca to authorize for emergency use, a senior official said on Monday.

While the state-run Indian Council of Medical Research and Indian Ministry of Health did not respond to Reuters request for comments, Serum Institute declined to offer one.
