Here are five things you must know for Thursday, Dec. 3:

1. — Stock Futures Mixed as U.S. Records Deadliest Day From Covid-19

Stock futures were mixed Thursday as a rally fueled by vaccine breakthroughs was tempered by the deadliest day in the U.S. from Covid-19, the disease caused by the coronavirus.

Contracts linked to the Dow Jones Industrial Average fell 20 points, S&P 500 futures were up 1 point and Nasdaq futures rose 24 points.

Wednesday was the deadliest day for Covid-19 fatalities, with more than 2,700 Americans dying from the disease, according to Johns Hopkins University. The number of Covid-19 patients in U.S. hospitals topped 100,000 for the first time.

The enthusiasm that followed Great Britain becoming the first western country to approve a Covid-19 vaccine – the shot from Pfizer and BioNTech – was dented by the realization the U.S. could be in for a very difficult winter until a vaccine is widely distributed.

The director of the Centers for Disease Control and Prevention warned that total deaths from Covid-19 could reach “close to 450,000” by February unless Americans take greater precautions.

“The reality is, December and January and February are going to be rough times,” said Dr. Robert Redfield, the head of the CDC. “I actually believe they’re going to be the most difficult time in the public health history of this nation.”

On Wednesday, the S&P 500 posted its second straight record close after House Speaker Nancy Pelosi and Senate Minority Leader Chuck Schumer called for stimulus talks to begin. Federal Reserve Chairman Jerome Powell and Treasury Secretary Steven Mnuchin urged Congress on Wednesday to approve a Covid-19 relief bill.

Asian shares finished mostly to the upside Thursday while stocks in Europe traded mixed.
