Microsoft co-founder Bill Gates said Wednesday that people could need multiple doses of a potential coronavirus vaccine to immunize themselves from the coronavirus. If necessary, the multiple doses could require more than 7 billion vaccinations to be administered worldwide.

"None of the vaccines at this point appear like they'll work with a single dose," Gates said. "That was the hope at the very beginning."

The billionaire philanthropist, who has donated $300 million towards the global effort to combat COVID-19 through the Bill & Melinda Gates Foundation, told "CBS Evening News" anchor and managing editor Norah O'Donnell that deploying a coronavirus vaccine will require a global effort.

...So-called wraparound home care services were created, on the fly, by Northwell Health to deal with the surge in coronavirus cases that New York experienced this spring. Now this model may help relieve health systems in the Sun Belt and other parts of the United States, where rising numbers of cases are putting extraordinary pressure on hospitals, filling intensive care units and sending providers scrambling to hire extra nurses and secure medical supplies.
