Hypothesis
What is the vaccination coverage among children aged 6–23 months during the 2004–05 influenza season?
Conclusion
About one-third of children received at least one dose of the influenza vaccine, but the rate of full vaccination was low.
Supporting Evidence
- 30% of children in Arizona received at least one dose of the vaccine.
- 27% of children in Michigan received at least one dose of the vaccine.
- 13% of children in Arizona were fully vaccinated.
- 11% of children in Michigan were fully vaccinated.
- Vaccination coverage was higher among younger children.
Takeaway
This study looked at how many young kids got their flu shots. It found that many got at least one shot, but not enough got the full two shots they need.
Methodology
Data was collected from immunization information systems in Arizona and Michigan to assess vaccination coverage among children aged 6–23 months.
Potential Biases
Some sites may not contribute their immunization data to the IIS, potentially underestimating vaccination coverage.
Limitations
The study results may not be generalizable to the entire U.S. population and the completeness of reporting by participating sites is unknown.
Participant Demographics
In Arizona, 50% were white, 32% Native American or Alaskan Native, 17% Hispanic, and 1% black or Asian; in Michigan, 85% were white, 9% black, 1% Asian, and 5% other or unknown.
