Most Americans to be vaccinated for COVID-19 by July, CDC chief expects

U.S. Centers for Disease Control and Prevention head Robert Redfield said he expects there to be about 700 million doses of vaccines available by late March or April, enough for 350 million people. "I think that's going to take us April, May, June, you know, possibly July, to get the entire American public completely vaccinated," Redfield told the U.S. Senate Health, Education, Labor and Pensions Committee. Redfield, U.S. Food and Drug Administration head Stephen Hahn, U.S. National Institute of Allergy and Infectious Diseases head Anthony Fauci and Health and Human Services official Brett Giroir were testifying on the COVID-19 pandemic, which has caused more than 200,000 deaths in the United States.
