On Monday, the head of the federal General Services Administration acknowledged that Biden is the apparent winner of this month's presidential election. That allows the incoming president to coordinate with federal agencies on plans for taking over on Jan. 20, despite ongoing efforts by President Donald Trump to overturn the election.

Widely admired in the financial world, Yellen would be the first woman to lead the department in a line stretching back to Alexander Hamilton in 1789, taking on a pivotal role to help shape policies at a perilous time.

On Monday, drugmaker AstraZeneca reported surprisingly good results from ongoing vaccine studies. It said its potential vaccine, which is being developed with Oxford University, was up to 90 per cent effective.

Last week, Pfizer and Moderna both reported study results showing their vaccines were almost 95 per cent effective. And, over the weekend, Regeneron Pharmaceuticals received U.S. government approval for emergency use of its COVID-19 treatment. The drug, which Trump received when he was sickened last month, is meant to try to prevent hospitalization and worsening disease from developing in patients with mild-to-moderate symptoms.
