Addressing Vaccine Acceptance in Carceral Settings Through Community Engagement

November 6, 2026 updated by: Yale University

The objective of this study is to identify a set of interventions that are effective in improving preventive healthcare engagement, including vaccination and chronic disease prevention, among incarcerated individuals and correctional staff in the Pennsylvania prison system.

Study Overview

Detailed Description

Aim 1: Identify promising strategies and implementation approaches for respiratory preventive health engagement, including vaccination, among correctional staff and formerly incarcerated individuals from high-performing correctional systems.

Aim 2: Select community-endorsed prevention strategies for a statewide correctional system.

Aim 3: Test the effectiveness of strategies to improve respiratory preventive health engagement using rapid-cycle, cluster randomized trials and related evaluative activities, as applicable.

Description

Inclusion Criteria:

  • All incarcerated people in the Pennsylvania DOC are included in the study population for these low risk interventions. In this each individual intervention, inclusion criteria will be based on where incarcerated people are housed and therefore what intervention they will be exposed to.

Exclusion Criteria:

  • Exclusion criteria will likely include severe physical or mental illness as these individuals are often incarcerated in special units which will not be included in the study (i.e. medical units).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Treatment as usual

Participants receive standard interventions currently in use (treatment as usual).

Experimental: ADVANCE Steering Committee chosen interventions

Interventions will be selected by the ADVANCE Steering Committee and will be rapidly deployed without additional effort on the part of front-line staff at four distinct levels: patient, provider, practice and prison level. Interventions will be tested one at a time in an iterative process. A participatory, assets-based framework will be used to identify acceptable and feasible strategies to improve vaccine acceptance. Each round of testing will include 1 month of preparation by the steering committee,12-week intervention period, and 2 months for analysis and rapid dissemination.
