WATCH: Biden unveils national strategy on COVID-19, announces vaccine supply purchases

WASHINGTON — President Joe Biden is announcing that the U.S. is purchasing an additional 100 million doses each of the two approved coronavirus vaccines for delivery this summer, with the government expecting to be able to deliver enough of the two-dose regimens to states this summer to vaccinate 300 million people.

Watch Biden’s remarks in the player above.

The additional purchases from drugmakers Pfizer and Moderna come as the Biden administration is trying to ramp up vaccine production and states’ capacities to inject them into arms. Biden is also announcing that vaccine deliveries to states and territories will be boosted to at least 10 million doses per week over the next three weeks.

Seeking to address concerns from state and local leaders that supplies have been inconsistent, prompting last-minute cancellations of booked appointments, the White House is also pledging to provide states with firm vaccine allocations three weeks in advance of delivery to allow for accurate planning for injections.
