Pfizer, Moderna Tell Congress a Big Jump in Vaccine Supply Is Coming

WEDNESDAY, Feb. 24, 2021 (HealthDay News) -- Officials from both Pfizer and Moderna delivered reassuring news about their COVID-19 vaccines to Congress on Tuesday: There will be a sharp rise in the delivery of doses in the coming month, and they will be able to provide enough doses to vaccinate most Americans by summer.

By the end of March, Pfizer and Moderna expect to have delivered a total of 220 million vaccine doses to the U.S. government, a significant uptick from the roughly 82 million doses that the U.S. Centers for Disease Control and Prevention says have shipped so far.
