National, state, and local area vaccination coverage among children aged 19-35 months--United States, 2007.

The National Immunization Survey (NIS) provides vaccination coverage estimates among children aged 19--35 months for each of the 50 states and selected urban areas. This report describes the results of the 2007 NIS, which provided coverage estimates among children born during January 2004-July 2006. Healthy People 2010 established vaccination coverage targets of 90% for each of the vaccines included in the combined 4:3:1:3:3:1 vaccine series and a target of 80% for the combined series. Findings from the 2007 NIS indicated that >/=90% coverage was achieved for most of the routinely recommended vaccines. The majority of parents were vaccinating their children, with less than 1% of children receiving no vaccines by age 19-35 months. The coverage level for the 4:3:1:3:3:1 series remained steady at 77.4%, compared with 76.9% in 2006. Among states and local areas, substantial variability continued, with estimated vaccination coverage ranging from 63.1% to 91.3%. Coverage remained high across all racial/ethnic groups and was not significantly different among racial/ethnic groups after adjusting for poverty status. However, for some vaccines, coverage remained lower among children living below the poverty level compared with children living at or above the poverty level. Maintaining high vaccination coverage and continued attention to reducing current poverty disparities is needed to limit the spread -preventable diseases and ensure that children are protected.
