The United States said it authorized the use of Pfizer Inc's COVID-19 vaccine on Friday, with the first inoculations expected within days, marking a turning point in a country where the pandemic has killed more than 295,000 people.
The U.S. Food and Drug Administration granted an emergency use authorization for the vaccine, developed with German partner BioNTech, which was shown to be 95% effective in preventing the disease in a late-stage trial. It said the vaccine can be given to people aged 16 and older.
Healthcare workers and elderly people in long-term care facilities are expected to be the main recipients of a first round of 2.9 million doses this month.
