Pfizer has announced that it will be able to supply more than 13 million doses of vaccine per week by mid-March doubling the current rate.  Effective in April, Moderna will deliver 40 million doses per month.  The announcements made by the respective CEO’s of the two companies were presented in written Congressional testimony.

If the contributions from the two companies are combined, the U.S. will have received 240 million doses by the end of March sufficient to vaccinate 120 million people.  To date, 75 million doses have been delivered with 64 million administered by states according to the Centers for Disease Control and Prevention.

The Johnson & Johnson vaccine has been approved and will soon enter the supply chain.

Distribution of the vaccine and actual administration is increasing as logistic problems are resolved. In theory up to 2.5 million doses could be administered each day given current resources.

The promise of additional vaccines is now raising the problem of vaccine hesitancy with approximately a third of those surveyed indicating either a wait-and-see approach or downright rejection of any vaccine. The Biden Administration has commissioned the National Ad Council to develop a promotional campaign intended to encourage adoption of vaccines especially in minority communities.
