Why This Indicator Matters

Vaccines help protect infants, children, and teens from serious diseases. Getting childhood vaccines allows children to develop immunity against diseases before they come into contact with them.
It also helps keep the community safe from these diseases spreading in families, schools, child care and in the broader community.  For more info, see CDC Vaccines- Who and when

Data Source: Maine Center for Disease Control. Quarterly Child Immunizations
Other sources report on 6 vaccines, but the 7 vaccines in the group, " 4313314 coverage." is the standard in Maine. The Maine Immunization Program conducts an immunization assessment on the 1st of each quarter (January, April, July, October) which includes all 2 year-olds in the State of Maine immunization registry, ImmPact, associated to a practice which enters client specific data. This assessment follows the standard Centers for Disease Control and Prevention childhood assessment criteria of 24-35 months of age immunized as of 24 months for the 7 vaccines listed in the definitions section.   

Children are counted based on the county of the physicians' practices, In Sagadahoc County for example, children may have their medical care in Brunswick which is Cumberland County, so would be included there.

Footnotes: This new series is based on the 4th quarter of the calendar year, as annual reports are no longer available.
