Brief Summary
The goal of this cluster, randomized controlled trial is to study the impact of mobile vaccine clinics and religious conferences on pediatric vaccination coverage. The main questions will be: does vaccination coverage change in geographic areas with the mobile vaccine clinics vs those areas without mobile vaccine clinics; and does vaccination coverage change in geographic areas with religious conferences on vaccination vs those areas without religious conferences. In repeated surveys, adult participants will respond about their children's vaccination status. Participants will not be individually randomized to the interventions. Rather, their geographical area will be randomized.

Conditions
Outcome Measures
Primary Outcomes (1)
Full vaccination
Number of participants fully vaccinated. Full vaccination means 1 dose of BCG; 3 doses of DTP; 3 doses of polio vaccine; 1 dose of measles-containing vaccine
Records from vaccination cards or clinic records 6 months since the start of the intervention
Study Arms (4)
Religious Conference
EXPERIMENTALClusters will have religious conference.
Religious Conference control
NO INTERVENTIONClusters will have not religious conference. Clusters' background characteristics matched to the Conference arm.
Vaccine-in-a-van
EXPERIMENTALClusters will have deployment of a mobile vaccine clinic ("vaccine-in-a-van").
Vaccine-in-a-van control
NO INTERVENTIONClusters will not have a deployment of a mobile vaccine clinic ("vaccine-in-a-van"). Clusters' background characteristics matched to the Van arm.
Interventions
The conference will invite local subdistrict-level imams and other religious leaders, along with a range of community health workers, including those not traditionally trained to give vaccines. During the conference there will be some sessions with everyone, and some that are broken down by profession. The conference topics will be developed in conjunction with the religious leaders, but will focus on the importance of infant health
For the vaccine-in-a-van concept, our community health worker will travel to different areas in the test subdistricts. These locations will be decided on in conjunction with the local health department and the research team's knowledge of the area. We will target areas which would have families with young children, particularly: schools, mosques, and sports fields. The purpose of the van will be to bring vaccines to the community, but also to put a human face (our community health worker) to vaccines outside of a clinical setting.

Reproducibility and replicability of studies are both extremely important. Therefore, we plan to upload a final dataset (along with code detailing my statistical analysis) to a public repository. This dataset will have personally identifiable information removed - and the geographic location will be coded by a number to prevent individuals being able to locate members of the study and identify them.
