President Joe Biden said he believes the US will be able to administer 1 million doses of Covid-19 vaccine each day in about the next three weeks
"I'm quite confident that we will be in a position within the next three weeks or so to be vaccinating people at the range of a million a day or in excess of that," he said on Monday.
Biden said manufacturers have said they are able to produce more vaccine "in a relatively short period of time and then continue that down the road."
"We have to meet that goal of a million a day," he said.
With that volume of vaccinations, Biden said there also needs to be enough infrastructure in place – which includes things like medical equipment to inject the vaccine into people's arms and freezing units to store the vials.
Biden also said there needs to be enough people to administer the doses and facilities were people can go to receive it, "which is not an easy task," he added.
"It's really important that we have the place, the facility, the circumstance where people can show up, stand in line and get their vaccine without having to stand in line for eight hours," he said. "All those mechanical things are really. They sound simple but they're all consequential when we're trying to get out a minimum of 100 million vaccinations in 100 days," he added.
"It's going to be a logistical challenge that exceeds anything we've ever tried in this country. But I think we can do that," Biden said.
