RESUMEN
OBJECTIVES: The federal Section 317 Immunization Program, administered by the Centers for Disease Control and Prevention (CDC), provides funding to support adult immunization efforts; however, current information on program implementation at the jurisdictional level is limited. We assessed the use of Section 317 and other funding sources to support routine adult immunization activities among the 64 immunization programs ("awardees"). METHODS: We conducted a survey and key informant interviews with awardees in October to December 2022 to collect quantitative and qualitative data on current adult vaccine purchase and program operation activities funded by Section 317 and other funding sources. We assessed total vaccine cost and data on vaccine purchase projections for each awardee with CDC's Cost and Affordability Tool for 2023. RESULTS: Immunization program managers or their designees from 62 of 64 awardees (97%) completed the survey; 12 awardees participated in key informant interviews. Of 62 awardees, 32 (52%) used a single funding source to support adult vaccine purchases, of which 29 (91%) used only Section 317 funds, 21 (34%) reported not planning to purchase ≥1 age-based recommended vaccine for adults in 2023, and 33 (53%) reported using Section 317 funds only to support adult immunization program operations. Key informant interviews showed varied operational activities among awardees, but 8 awardees stated the need for additional staff to expand adult immunization program services in health care provider education (n = 5), program administration (n = 5), and site visits (n = 6). CONCLUSIONS: Additional efforts are needed to understand how to better support routine adult immunization activities implemented at the jurisdictional level.
