Evolving Interoperability Across a State Public Health Immunization Registry and Electronic Health Records.

The critical need for system interoperability and robust information infrastructure in public health was highlighted during the COVID-19 pandemic. An assessment of the evolving interoperability between immunization information system (IIS) in a state-based public health agency and electronic health records (EHRs) including pandemic-driven evolution/use was conducted. The Minnesota Immunization Information Connection (MIIC), the IIS for Minnesota (US) supports interoperability with EHRs using HL7v2.

SARS-CoV-2 Exposure and Infection Among Health Care Personnel - Minnesota, March 6-July 11, 2020.

Health care personnel (HCP) are at increased risk for infection with SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), as a result of their exposure to patients or community contacts with COVID-19 (1,2). Since the first confirmed case of COVID-19 in Minnesota was reported on March 6, 2020, the Minnesota Department of Health (MDH) has required health care facilities* to report HCP exposures to persons with confirmed COVID-19 for exposure risk assessment and to enroll HCP with higher-risk exposures into quarantine and symptom monitoring. During March 6-July 11, MDH and 1,217 partnering health care facilities assessed 21,406 HCP exposures; among these, 5,374 (25%) were classified as higher-risk (3).

Measles Outbreak in Minnesota (2017): Roles of an Immunization Information System.

The Minnesota Department of Health used its Immunization Information System-the Minnesota Immunization Information Connection-to respond to an outbreak of measles in the state in 2017 by assisting with the exclusion of unvaccinated exposed individuals from public activities, providing members of the public with their immunization records, and monitoring measles, mumps, and rubella vaccine uptake. Use of the Immunization Information System was found to be an efficient and sustainable tool in responding to the outbreak.

Timeliness of Receipt of Early Childhood Vaccinations Among Children of Immigrants - Minnesota, 2016.

Receiving recommended childhood vaccinations on schedule is the best way to prevent the occurrence and spread of vaccine-preventable diseases (1). Vaccination coverage among children aged 19-35 months in the United States exceeds 90% for most recommended vaccines in the early childhood series (2); however, previous studies have found that few children receive all recommended vaccine doses on time (3). The Minnesota Department of Health (MDH), using information from the Minnesota Immunization Information Connection (MIIC) and the MDH Office of Vital Records, examined early childhood immunization rates and found that children with at least one foreign-born parent were less likely to be up-to-date on recommended immunizations at ages 2, 6, 18, and 36 months than were children with two U.
