Effectiveness of a mailed reminder on the immunization levels of infants at high risk of failure to complete immunizations

Abstract

The Ohio Department of Health initiated a program of mailing an immunization reminder to the mothers of 6-mth-old children predicted to be at high risk of failure to receive vaccinations based on birth certificate information. The evaluation results indicated a 50% gain in immunizations amongst children whose parents received the letter when compared with those not receiving the letter.
