U.S. Buys 100 Million Extra Doses of Pfizer/BioNTech, Moderna Vaccines

The U.S. government has purchased 100 million additional doses of both the Pfizer/BioNTech and Moderna messenger RNA (mRNA)-based COVID-19 vaccines in an effort by the Biden administration to ramp up inoculations.

With the new orders, the government has bumped up its total number of doses purchased from the two drugmakers to 600 million. The U.S. is on track to have enough supply to inoculate 300 million Americans by the end of July, according to President Biden.

Moderna said that it expects to deliver the additional supply of doses before the end of July and continues to scale up its manufacturing in the U.S. and abroad. Pfizer did not comment on its new supply commitment.
