Abstract

BACKGROUND. Beginning in 2002 the Advisory Committee on Immunization Practices

encouraged, when feasible, annual influenza vaccination of all children aged 6 to

23 months and household contacts and out-of-home caregivers of children <2

years of age.

OBJECTIVE.We sought to report influenza vaccination coverage for the 2002–2003

and 2003–2004 influenza seasons among children aged 6 to 23 months according

to demographic and immunization-provider characteristics.

METHODS. Data from the 2003 and 2004 National Immunization Survey were analyzed.

Two measures of childhood influenza vaccination are reported: receipt of

>1 influenza vaccination and full vaccination (ie, receipt of the appropriate

number of doses on the basis of previous vaccination history). x2 tests and

logistic-regression analyses to test for associations between influenza vaccination

status and demographic characteristics were performed.

RESULTS. In the 2002–2003 and 2003–2004 influenza seasons only 7.4% and 17.5%,

respectively, of children aged 6 to 23 months received >1 influenza vaccination,

whereas only 4.4% and 8.4%, respectively, were fully vaccinated. In both seasons,

adjusted influenza vaccination coverage was significantly lower among children

living below the poverty level; non-Hispanic black children; older children; children

with less-educated mothers; children vaccinated only at public clinics; and

children not residing in a metropolitan statistical area.

CONCLUSIONS. During the first 2 years of the Advisory Committee on Immunization

Practices’ encouragement for children aged 6 to 23 months to receive influenza

vaccination, coverage was low, with significant demographic differences in receipt

of vaccination. Beginning with the 2004–2005 influenza season, they replaced the

encouragement with a recommendation that children aged 6 to 23 months receive

annual influenza vaccination. Substantial work remains to fully and equitably

implement this new recommendation and ensure vaccination with 2 doses for

previously unvaccinated children.
