The CDC is establishing one or more ID/IQ contracts for the purchase of standard commercial adult vaccines. The primary intention is to procure vaccines for the 2026-2027 season, with a requirement to also purchase for the 2025-2026 season. The vaccines will be purchased for NCIRD's immunization awardees, including all fifty state health departments, several large city programs, and U.S. Territories, to support their adult immunization programs. Awardees may also opt to purchase additional quantities using state and local funds. The contracts aim to utilize Section 317 vaccine purchase funds to obtain vaccines at prices below the commercial marketplace.
