Biden said additional funding from Congress will be needed early next year to fund the rest of the distribution efforts for the vaccine and to prevent the United States' response from stalling.to take the vaccine because many have become skeptical about its usefulness, Biden said.
Biden also said he wants to have US schools open by the end of the first 100 days of his presidency, depending on whether Congress passes a new COVID-19 relief bill.
The US administration is expected to approve two vaccine candidates in the coming days to administer tens of millions of doses in December with hundreds of millions more in subsequent months. The plan is to vaccinate almost all US citizens by the end of the second quarter of 2021.
