Reducing Vaccination Disparities During a National Emergency Response: The US Mpox Vaccine Equity Pilot Program.

Context: In response to the first reported mpox cases in May 2022, the US government implemented plans to bring testing, treatment, and vaccines to communities disproportionately affected by mpox-including the population of men who have sex with men (MSM) and Black/African American and Hispanic/Latino men, 2 subpopulations experiencing vaccination disparities. We describe the development and implementation of the US Mpox Vaccine Equity Pilot Program (MVEPP), characteristics of completed vaccination projects, and challenges that occurred. We also discuss opportunities for reducing vaccination disparities in future outbreaks.

Program: To address reported vaccination disparities, the US government launched MVEPP in 2 phases. Phase 1 centered around public events attended by large numbers of gay, bisexual, and other MSM, such as Pride festivals. Phase 2 asked health departments to propose mpox vaccination projects specifically aimed at reducing or eliminating racial/ethnic and other demographic disparities in mpox vaccination.

Implementation: MVEPP received 35 vaccination project proposals. We analyzed data from 22 completed projects that resulted in 25 675 doses of JYNNEOS administered. We note 3 innovative strategies that were implemented in several projects: direct collaboration with organizations providing services to MSM and transgender women; implementation of MVEPP projects in unique nonclinical community settings and at venues frequented by MSM and transgender women; and offering an array of services as part of mpox vaccination projects, rather than offering only mpox vaccination.

Evaluation: MVEPP highlighted the importance of recognizing and working to eliminate racial/ethnic and other disparities in access to medical countermeasures during a public health emergency. Jurisdictions developed and implemented innovative strategies to bring mpox vaccination and related services to communities disproportionately affected by mpox-including MSM and the subpopulations of Black/African American and Hispanic/Latino MSM. Lessons learned from MVEPP may inform efforts to reduce disparities during future public health responses.
