Multiple vaccine doses could be necessary to protect from coronavirus, Bill Gates says

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.

Foreign Aid from top donors drops even as need soars

JOHANNESBURG (AP) — A new snapshot of the frantic global response to the coronavirus pandemic shows some of the world’s largest government donors of humanitarian aid are buckling under the strain: Funding commitments, for the virus and otherwise, have dropped by a third from the same period last year.

C.D.C. says the number of people infected ‘far exceeds the number of reported cases’ in parts of the U.S.

 The number of people infected with the coronavirus in different parts of the United States was anywhere from two to 13 times higher than the reported rates for those regions, according to data released Tuesday by the Centers for Disease Control and Prevention.

The findings suggest that large numbers of people who did not have symptoms or did not seek medical care may have kept the virus circulating in their communities. The study is the largest of its kind to date, although some early data was released last month.

“These data continue to show that the number of people who have been infected with the virus that causes Covid-19 far exceeds the number of reported cases,” Dr. Fiona Havers, the C.D.C. researcher who led the study, said in an email. “Many of these people likely had no symptoms or mild illness and may have had no idea that they were infected.”
