“The US has invoked the Defence Act and banned export of raw materials. This is as good as banning vaccines. All vaccine producers are facing difficulties because of this,” Poonawalla had said. It has already stalled the Novavax vaccine’s production. “Stock-piling of Novavax would happen to the tune of 50 per cent more if we had access to US raw materials. Till the month of April, it was not really coming in the way. From this month onwards, whatever we stockpile of Novavax would be half of what we could do, had it not been for US restrictions,” he had said.
