BACKGROUND:
The ACIP has recommended that all children aged 6-23 months be vaccinated against influenza. The San Diego County Immunization Program conducted population-based random digit dial telephone surveys in the spring of 2004 to gather information on influenza vaccination in this young population.
OBJECTIVE:
Establish and monitor influenza immunization coverage levels for children aged 6-23 months in San Diego County. Identify possible strategies for improving immunization coverage levels.
METHOD:
In the spring of 2004, 1,165 parents of children aged 6-23 months completed telephone interviews. The dataset was divided into three groups: a) “primary” children who were between the ages of 6 and 23 months during the entire time period from October 2003 to January 2004, b) children who phased in, or c) children who phased out of the recommended age group during the period under study.
RESULT:
29.0% of the primary children had received an influenza vaccination in the past year. 21.9% of the phase-in children, and 19.5% of phase-out children, had received an influenza vaccination in the past year. 10.4% of the primary children were up-to-date on both of their influenza shots in the past season, as recommended by the CDC. 7.5% of the phase-in children, and 6.1% of the phase-out children, were up-to-date on the recommended two doses of influenza vaccine for the previous influenza season. Further analysis will be performed to determine predictors of receiving the influenza vaccination.
CONCLUSION:
This data provided an estimate for influenza vaccine coverage among children 6-23 months. We find that influenza vaccination coverage rates are low, and further analysis of this issue will be needed to develop strategies for increasing influenza vaccine coverage rates in this population.
LEARNING OBJECTIVES:
Describe the process for assessing coverage levels and predictors of influenza vaccination among children aged 6-23 months in San Diego County.
