This initiative includes a minimum order of 100 doses and a maximum of 6 million doses, with strict compliance to FDA standards and specific delivery requirements. Proposals are due by November 12, 2024, and interested parties should direct inquiries to Matheu Wilson at zlb4@cdc.gov or David Dombeck at vwj8@cdc.gov. The contract period will extend from the date of award through February 28, 2026.
