Increasing Appropriate Vaccination: Client Reminder and Recall Systems

Task Force Finding

The Community Preventive Services Task Force recommends client reminder and recall interventions based on strong evidence of effectiveness in improving vaccination rates:

  1. In children, adolescents and adults
  2. In a range of settings and populations
  3. When applied at different levels of scale—from individual practice settings to entire communities
  4. Across a range of intervention characteristics (e.g., reminder or recall, content, theoretical basis and method of delivery
  5. Whether used alone or with additional components.

Read the full Task Force Finding and Rationale Statement for details including implementation issues, possible added benefits, potential harms, and evidence gaps.

Intervention Definition

Client reminder and recall interventions are used to remind members of a target population that vaccinations are due (reminders) or late (recall). Reminders and recalls differ in content and are delivered by various methods—telephone, letter, postcard, text messages, or other. Most reminder and recall notices are tailored for individual clients, and many are accompanied by educational messages about the importance of vaccination.

About the Systematic Review

The Task Force finding is based on evidence from a Community Guide systematic review completed in 2008 (19 studies, search period 1997-2007) combined with more recent evidence (10 studies, search period 2007-2012). The finding updates and replaces the 2008 finding for Client Reminder and Recall Systems.

This review was conducted on behalf of the Task Force by a team of specialists in systematic review methods, and in research, practice and policy related to increasing appropriate vaccination. Subscribe External Web Site Icon to be notified as new materials on this topic become available.
