Data from the MCIR were used to show vaccine coverage declines among most children at milestone ages in May 2020 compared to previous May estimates. Data key points:

  • From January through April 2020, the number of non-influenza vaccine doses given to children aged <18 years decreased 21.5% compared to the average for the same period in 2018 and 2019.
  • The number of doses given to children aged ≤24 months declined 15.5%.
  • Up-to-date vaccinations have declined to <50% among most children ≤2 years.
  • Coverage for the May 2020 child cohorts of children at ages 1, 3, 5, 7, 16, 19 and 24 months was lower for Medicaid-enrolled children compared with children not enrolled in Medicaid.
  • Among those aged 5 months, up-to-date status declined from approximately two-thirds during May 2016-2019 (66.6%, 67.4%, 67.3%, 67.9%, respectively) to less than half (49.7%) in May 2020.

About Michigan Care Improvement Registry, MCIR

The Michigan Care Improvement Registry (MCIR) was created in 1998 to collect reliable immunization information for children and make it accessible to authorized users. A 2006 change to the Michigan Public Health Code enabled the MCIR to transition from a childhood immunization registry to a lifespan registry including citizens of all ages in the MCIR. MCIR benefits health care organizations, schools, licensed childcare programs, pharmacies and Michigan’s citizens by consolidating immunization information from multiple providers into a comprehensive immunization record. This consolidation reduces vaccine-preventable diseases and over-vaccination, allowing providers to view up-to-date patient immunization history in one system.
