Abstract:

U.S. vaccination coverage is monitored by nationally representative surveys. Surveys provide consistent methodology across states but limitations can include limited age group coverage, cost, lack of provider verification, and timeliness. Immunization Information Systems (IIS) contain provider-verified population-based immunization surveillance data. We propose to estimate national vaccination coverage among 19-35 month olds using data from six IIS sentinel sites (IIS-SS) that contain 10% of the U.S. population by direct standardization and model-based approaches, and compare with the National Immunization Survey. The direct standardization approach requires linked demographic data from birth certificates and vaccination data from IIS-SS. The model-based approach requires county-level socio-demographic data from the Area Health Resource File and vaccination data from IIS-SS. We will employ a Poisson regression model to estimate vaccination coverage using IIS-SS data and extrapolate to the remaining counties in the United States. This analysis will assess the ability of IIS-SS to complement surveys by producing timely, low-cost national vaccination coverage estimates.
