- 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.
- 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).
- Children
in the Q1/2004-Q4/2004 National Immunization
Survey were born between February 2001
and May 2003.
- One
or more doses of influenza vaccine administered
between 9/1/2003 - 12/31/2003.
- 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.
