Area of Science:

  • Public Health
  • Epidemiology
  • Immunization Practices

Background:

  • The 2017 Minnesota measles outbreak, primarily affecting Somali-American children, highlighted vulnerabilities in community immunity.
  • Understanding vaccination coverage is crucial for preventing infectious disease outbreaks.

Observation:

  • Measles-Mumps-Rubella (MMR) vaccine coverage among Minnesota kindergarteners (2012-2016) varied significantly by school district.
  • Private schools exhibited notably lower MMR coverage (83.00%) compared to public schools.

Findings:

  • MMR coverage ranged from 58.3% to 100% across Minnesota districts.
  • Geographic proximity and modest coverage rates in some areas posed potential risks for future outbreaks.

Implications:

  • Heterogeneous MMR coverage necessitates targeted public health interventions to bolster community immunity.
  • Addressing disparities in vaccination rates, particularly in private schools, is essential for outbreak prevention.
