Serum Institute of India (SII) CEO Adar Poonawalla on Friday said the US needs to lift its embargo on raw material exports to help ramp up vaccine production. SII is currently manufacturing anti-coronavirus vaccine Covishield, developed by Astrazeneca and Oxford University. The vaccine is not only being used in India, but exported to a number of countries. 

Poonawalla had earlier admitted that SII has been facing problems in sending out required number of batches of vaccines due to the bureaucratic and government-related hurdles.
