Improving Immunization Rates During the 2019 Measles Outbreak

Area of Science:

• Pediatrics
• Public Health
• Immunization

Background:

• Measles outbreaks in the US in 2019 raised public health concerns.
• Pediatric immunization rates are crucial for community health.
• Low vaccination rates can lead to outbreaks of preventable diseases.

Purpose of the Study:

• To assess the effectiveness of a provider-led intervention to increase measles immunization rates in pediatric patients.
• To evaluate the impact of personalized communication on parental vaccination decisions.

Main Methods:

• Identified under-immunized pediatric patients using electronic medical records (EMR).
• Reviewed and updated patient charts for immunization accuracy.
• Sent personalized letters from primary care providers and CDC measles fact sheets to parents of unvaccinated children.

Main Results:

• Out of 44 patients whose parents received the mailing, 5 children received the measles, mumps, and rubella (MMR) vaccine.
• Among the 20 patients whose parents had previously documented intent to not vaccinate, none received the MMR vaccine.
• The intervention showed a modest increase in MMR immunization rates for some children.

Conclusions:

• Personalized provider guidance can encourage measles immunization among hesitant parents.
• Provider advice was ineffective in changing the minds of parents firmly against vaccination.
• Targeted communication strategies are important, but may not overcome deeply held anti-vaccination beliefs.
