The White House on Monday did not respond to questions on the request by Serum Institute of India to lift export ban on certain raw materials needed for ramping up production of COVID-19 vaccine. The question in this regard was asked twice on Monday -- once during the morning White House briefing on COVID-19 and later during the daily news conference by White House Press Secretary Jen Psaki.

The Serum Institute of India has been saying that the Biden administration is blocking exports of raw materials that it needs to make COVID vaccines, and the Serum Institute has also urged President Biden to lift that embargo. So I wanted to ask which raw materials are at issue here? And do you have any plans to address Serum's concerns? asked a reporter during the morning news conference by the White House COVID-19 Response Team.
