Trump administration renews public health emergency after urging from states The news will come as a relief to health care groups who worried the declaration might not be renewed before it lapses July 25 POLITICO

The Trump administration has renewed the public health emergency for the coronavirus, ensuring that critical resources to fight the pandemic can continue while much of the country battles rising caseloads.

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.
