The Biden administration is planning to purchase an additional 200 million doses of Covid-19 vaccine, marking a stepped-up effort to vaccinate the vast majority of Americans this year.
Federal officials negotiating for the new supply expect to receive 100 million doses each from Moderna and Pfizer, in deals set to boost the nation’s total vaccine capacity to 600 million.
That would give the U.S. the ability to eventually vaccinate up to 300 million Americans, President Joe Biden said on Tuesday.
