COVID-19 vaccine makers tell Congress to expect a big jump in the delivery of doses over the coming month.
The companies insisted Tuesday, Feb. 23, at a hearing that they will be able to provide enough vaccine for most Americans by summer.
By the end of March, Pfizer and Moderna expect to have provided the U.S. government with a total of 220 million vaccine doses, up sharply from the roughly 75 million shipped so far.
AdLooking ahead to summer, Pfizer and Moderna expect to complete delivery of 300 million doses each, and J&J aims to provide an additional 100 million doses.
āThe most pressing challenge now is the lack of supply of vaccine doses,ā Rep. Diana DeGette, a Colorado Democrat, said as she opened the hearing.
