2009 H1N1 vaccination in Minnesota: an evaluation by ZIP code

Area of Science:

• Public Health
• Epidemiology
• Health Disparities

Background:

• The 2009 pandemic H1N1 influenza outbreak necessitated widespread vaccination efforts.
• Understanding vaccination patterns is crucial for addressing public health challenges and health disparities.

Purpose of the Study:

• To analyze 2009 H1N1 influenza vaccination data at the ZIP code level in Minnesota.
• To identify demographic and socioeconomic factors associated with H1N1 vaccination rates.

Main Methods:

• Utilized Minnesota Immunization Information Connection (MIIC) data from 2009-2010.
• Conducted a ZIP code-level analysis of H1N1 vaccination coverage.
• Stratified analysis by urban and rural locations.

Main Results:

• Only 23% of Minnesotans were vaccinated against H1N1 influenza.
• Significant associations found between vaccination rates and poverty, non-Caucasian residency, and median family income.
• Urban vaccination rates correlated with median family income, while rural rates correlated with the percentage of non-Caucasian residents.
• Private facilities administered most H1N1 vaccines, with higher proportions in urban (81.5%) versus rural (53.2%) areas.

Conclusions:

• Socioeconomic status and race are significant factors influencing H1N1 vaccination coverage.
• Distinct urban-rural differences exist in the determinants of H1N1 vaccination.
• Further research is needed to elucidate the reasons behind these observed disparities in vaccination uptake.
