- Vaccine administration data are updated with data as of 12 a.m. on the Sunday prior.
- Health equity data are updated bi-weekly on Thursdays with data as of the previous Friday.
- Unless otherwise noted, all denominators based on 2019 American Community Survey (ACS) 5-year estimates for the state of Minnesota available at United States Census Bureau: Explore Census Data.
- All data by county is based on residence.
- Statewide estimates by age and gender are based on ACS tables DP05 and S0101, except for the 5-11 and 12-15-year-old age groups, which are based on summing the county-level estimate based on ACS table B01001. The age groups have been split based on the assumption that ages are equally distributed within age groups.
- Vaccine administration data are based on vaccination records in the Minnesota Immunization Information Connection (MIIC), a confidential immunization information system. Immunizations in MIIC are submitted by participating health care providers.
- Providers who receive vaccine from MDH must submit COVID-19 vaccination information to MIIC within 24 hours; pharmacies have 72 hours. Providers getting vaccine directly from the federal government are not required to report to MIIC, but some may.
- MIIC is a useful resource to monitor state and county immunization coverage in Minnesota. The data can also help to identify at-risk populations and encourage public health actions and policies aimed at increasing immunization. The data cannot tell us why people are not vaccinated.
- However, MIIC data may underestimate the actual number of people receiving vaccines due to several limitations:
- While it is a requirement for most providers to report COVID-19 vaccine administration data to MIIC, some data may not be submitted to MIIC properly or there could be errors in the data that result in missing immunization information. MDH staff monitor and address any lapses in data exchange to ensure that timely and accurate COVID-19 vaccination information is submitted.
- Cross border-state immunization data exchange currently occurs with Iowa, Wisconsin, and North Dakota. Vaccines received in Iowa, Wisconsin, and North Dakota when the person gave a Minnesota address are in MIIC. At this time there is no similar data exchange with South Dakota.
- Age and gender are self-reported at the time of vaccination.
- Due to data collection and reporting timing, there may be discrepancies between data from the Minnesota Department of Health (MDH) and other sources.
