The United States is buying 300 million doses of an unproven COVID-19 vaccine produced by AstraZeneca.
It has promised up to $1.2 billion to buy a third of the company’s planned production of one billion doses.
After President Donald Trump demanded a vaccine, the U.S. Department of Health made the deal with AstraZeneca which got the vaccine from the University of Oxford in England.
“This contract with AstraZeneca is a major milestone in Operation Warp Speed’s work toward a safe, effective, widely available vaccine by 2021,” U.S. Health Secretary Alex Azar said.
Immunity to the new coronavirus is uncertain and so the use of vaccines unclear.
