  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.


  2. For Influenza vaccines, age-eligible children were 6-23 months of age during the 9/1/2003-12/31/2003 time period. Children who were age-eligible for influenza vaccines represented a subset of all children included in the NIS (unweighted n=13,831).


  3. Children in the Q1/2004-Q4/2004 National Immunization Survey were born between February 2001 and May 2003.


  4. One or more doses of influenza vaccine administered between 9/1/2003 - 12/31/2003.

  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 9/1/2003 to either the date of interview or 1/31/2004.
    2. At least one dose of influenza vaccine prior to 9/1/2003; then at least one dose of influenza vaccine from 9/1/2003 - 12/31/2003.
