Average completion rates for routine childhood and adolescent vaccinations in Michigan decreased from 2017 to 2023, according to a study published in Pediatrics in August. The study, which analyzed data from the Michigan Care Improvement Registry, compared completion rates across all Michigan counties.

In an email to The Michigan Daily, Dr. Kao-Ping Chua, senior author of the study, wrote that researchers focused on a seven-vaccine series for children and a six-vaccine series for adolescents, and found that completion rates for both decreased over the six-year period.
