Brief Summary
The objective of this study was to assess the relative effectiveness of reminder/recall strategies among children who live in an urban area targeting alternative age-specific milestones.
7 and 19 month recall groups: children not up to date for at least one vaccination at the time of notification
12 month reminder group: 12 months of age at time of notification
Hib vaccination series was not assessed due to a vaccine shortage
Exclusion Criteria:
Children were ineligible for notifications if they were designated in the Michigan Care Improvement Registry (MCIR)as having died, documented previously as having moved out of the jurisdiction ("Moved or Gone Elsewhere" (MOGE)), opted out of MCIR by their parent, or if they had been previously mailed for MCIR reminder/recall activity in the prior 60 days.
