Risk Factors for Delayed Immunization Against Measles, Mumps, and Rubella in Colorado Two-Year-Olds

Abstract

Based on our findings of the importance of immunization knowledge and demographic characteristics as risk factors for delayed immunization, we suggest that a message (the recommended age for immunizations) and a target group for that message (families who move frequently, have older children, and are headed by younger parents) be evaluated as an intervention to improve immunization rates.
