In a joint statement Wednesday morning, the Department of Health and Human Services and Department of Defense announced the purchase of 100 million additional doses of the Pfizer-BioNTech COVID-19 vaccine. This brings the total doses of Pfizer’s vaccine bought by the federal government to 200 million. The terms of agreement state Pfizer will deliver at least 70 million of those doses by the end of June 30, 2021, and the remaining doses no later than July 31, according to the statement. HHS Secretary Alex Azar said in the statement, “This new federal purchase can give Americans even more confidence that we will have enough supply to vaccinate every American who wants it by June 2021.”
