Estimated Vaccination Coverage¹ with Influenza Vaccine
Among Age-eligible Children² by State and Immunization Action Plan Area
US, National Immunization Survey, 2005³

¹ The 95% confidence intervals are approximations, particularly in states or immunization action plan areas with low coverage.
   In these areas, the 95% CI may include zero or negative values as a result of the approximation breaking down.
   Estimate=NA (Not Available) if the unweighted sample size for the numerator was <30 or (CI half width)/Estimate > 0.5 or (CI half width) >10.
   Estimates presented as point estimate (%) ± 95% Confidence Interval.

² For Influenza vaccines, age-eligible children were 6-23 months of age during the 9/1/2004-12/31/2004 time period.
   Children who were age-eligible for influenza vaccines represented a subset of all children included in the NIS (unweighted n=12,056).

³ Children in the Q1/2005-Q4/2005 National Immunization Survey were born between February 2002 and July 2004.

⁴ One or more doses of influenza vaccine administered between 9/1/2004 - 12/31/2004.

⁵ Children were considered fully vaccinated if they received either of the following:
   (1) No doses of influenza vaccine prior to 9/1/2003; then 2 doses of influeza from 9/1/2004 to either the date of interview or 1/31/2005.
   (2) At least one dose of influenza vaccine prior to 9/1/2004; then at least one dose of influenza vaccine from 9/1/2004 - 12/31/2004.
