- Minnesota Immunization Information Connection (MIIC) immunization information system.
- MIIC data may underestimate the actual percent of children receiving vaccines because: (1) health care provider participation in MIIC is voluntary, (2) the MIIC population may include children who have moved, and (3) cross border-state immunization data exchange is limited to Wisconsin and North Dakota.
- The MIIC population used to calculate childhood immunization rates is all individuals ages 24-35 months in MIIC.
- To protect privacy, MIIC subpopulations of 10 or fewer are displayed on the map in white, indicating “data not shown.” These subpopulations are also indicated by two asterisks (**) in the table and pop-up window.
- 2022 Data: Vaccination coverage among children ages 24-35 months in MIIC. Includes children born July 2019 through June 2020 who were up to date at 24 months. Analyzed as of July 2022.
