Increasing Appropriate Vaccination: Client Reminder and Recall Systems
Client reminder and recall interventions involve reminding 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, or other. Most reminder systems involve a specific notification for a specific client, and may be accompanied by educational messages regarding the importance of immunization for the targeted vaccine.
Summary of Task Force Recommendations and Findings
- In children and adults
- In a range of settings and populations
- When applied at different levels of scale from individual practice settings to entire communities
- Across a range of intervention characteristics (e.g., reminders and recall, content, theoretical basis and method of delivery)
- When used alone or with additional components
Results of the Original and Updated Systematic Reviews
The Task Force recommendation is based on evidence from an original review (search period 1980-1997) and an updated review (search period 1997-2007). Updates of reviews are conducted to incorporate more recent evidence.

Original Review (search period 1980–1997)
Forty-two studies qualified for the original systematic review.
Updated Review (search period 1997–2007)
Twenty studies were identified in the search period considered in this update.
- Median increase in vaccination coverage:
- Overall: 6.1 percentage points (20 studies)
- Client reminder and recall alone: 5.1 percentage points (12 studies)
- Client reminder and recall combined with additional components: 10 percentage points (8 studies)
- Reviewed studies evaluated the effectiveness of client reminder and recall interventions in a wide range of client and provider populations and settings.
These updated results were based on a recent systematic review of available studies, by a team of specialists in systematic review methods, and experts in research, practice and policy related to vaccinations to prevent diseases.
