SII is developing the vaccine in India, and had earlier said it was hoping for the emergency use approval by the end of this month or January in India.
The government was yet to place a purchase order for the Covishield vaccine, Cyrus Poonawalla, chairman of Poonawalla Group that includes SII, said.
"SII is ready to distribute the vaccine once the approval comes in. India will come first, then other countries," he added.

According to officials, more than 154,000 healthcare workers have been identified to help conduct the vaccination drive and the country had enough cold chain capacity to innoculate the first 30 million people.
