The United States will not take part in the launching of a global initiative on Friday to speed the development, production and distribution of drugs and vaccines against COVID-19, a spokesman for the U.S. mission in Geneva said.
"There will be no U.S. official participation", he said in an email reply to a query.
"We look forward to learning more about this initiative in support of international cooperation to develop a vaccine for COVID-19 as soon as possible."
