Moderna is set to file Monday for emergency use authorization of its Covid-19 vaccine, which new data shows to be more than 94% effective. The filing follows Pfizer's emergency use request on Nov. 20 and means Moderna's drug could be shipped out to Americans in a matter of weeks. Moderna's vaccine doesn't require storage temperatures as cold as Pfizer's, easing supply-chain complications.
Here are some of the biggest developments Monday:

The following data was compiled by Johns Hopkins University:
- Global cases: More than 62.84 million
