When developing integration regarding immunization services and/or interventions, program compatibility is a critical component.  Matching immunization programs to other appropriate services and/or interventions requires an in depth look at health worker skills, the target populations in mind, immunization and/or treatment options and characteristics, and program objectives.  It is also important to provide a high quality of training to staff in order to achieve high coverage with multiple services and/or interventions.  All of these characteristics and more are essential to integration with immunization programs because the characteristics build upon each other, often leading to stakeholder support for further integrated programming.  Integration with immunization programs can lead to strengthening of immunization services and where immunization coverage is low.  [i]
