President-elect Joe Biden will get his second vaccine dose in public on Monday “to continue to instill confidence in the vaccine’s safety and efficacy,” said incoming White House press secretary Jen Psaki.

This will be 21 days after Biden received the first dose, she said.

When Vice President-Elect Kamala Harris receives her second dose, it will also be in public, she said.

Psaki added, “The Biden-Harris transition team today started to vaccinate incoming members of the administration. Up to 35 individuals will be vaccinated.”

“These individuals are people who will be in close proximity to the President or Vice President, who are critical members of the National Security team or are Cabinet nominees in the line of succession to the presidency,” she said. “These vaccinations are being conducted now so that these individuals can complete their inoculation shortly after January 20. The vaccine being used for this purpose is coming from supplies previously allocated to the White House medical unit.”

State Farm Stadium, home of the Arizona Cardinals, will open as a 24/7 vaccination site on Monday, Gov. Doug Ducey said.

The site aims to "vaccinate thousands more individuals each day as Maricopa County, the state’s largest county, moves into Phase 1B of vaccine distribution," the governor’s office said. “The start of that phase prioritizes protective service workers, teachers and K-12 school staff, child care workers, and those age 75 and older.”

State Farm Stadium will offer vaccines beginning Monday for law enforcement and other protective service workers. Appointments for others in Phase 1B and Phase 1A will be available starting Tuesday.

In New York, daily cases are nearly 50% higher than they were during the spring surge.

The U.S. surpassed 132,000 patients in hospitals this week -- meaning more people were hospitalized than during the peak of the spring and summer surges combined.

Arizona, Nevada and Alabama currently hold the highest hospitalizations rates per million people in the country.

Thursday marked the nation's deadliest day on record with 4,085 deaths, according to data collected by Johns Hopkins University.
