Children: Immunization Data for 2 Year-Old
Child immunization data includes the percent of children that received the recommended doses of , , , , , and vaccines and the by age 24 months (2 years old). Iowa immunization data and rates are available in interactive maps and tables by single antigen and the completed series. These data provide immunization rates based upon a recommended vaccination series identified by the Advisory Committee on Immunization Practices (ACIP) and the Centers for Disease Control and Prevention (CDC). These data can identify trends and patterns in immunization coverage over time and in different geographic areas.
The Immunization Program uses data from the Immunization Registry Information System (IRIS) to calculate county and state immunization rates for 2-year-old children. The data includes patients served by both public and private health care providers with a record in IRIS that have a zip code and are an “active” patient within a health care provider organization. The Year selected in the visualization will include children turning 2 years-old in that year. For example, the 2019 results include children born between 01/01/2017 - 12/31/2017.

- County 2 Year Old Census Population: The Number of 2 Year Olds in the County, based on census estimates.
- Rate of Immunization by Children in IRIS: The Number of Immunized Patients divided by the number of same-aged children and geographic area recorded in IRIS.
- Rate of Immunization by County Population: The Number of Immunized Patients divided by the County 2 Year Old Population.
