Communitywide activities can provide information to a target population. No studies were found that evaluated the effectiveness in changing individuals' knowledge and attitudes about vaccinations, and no studies have evaluated anything other than printed material. Variable effects were found in two studies that evaluated the impact of vaccination information statements on knowledge and attitudes about vaccination. Client or family incentives . Financial or other incentives may serve to motivate acceptance of vaccinations.
Incentives can be rewards or penalties.
Only three studies of this intervention were identified. One study found that incentives did not result in a statistically significant change in vaccination coverage. Client-held medical records . This intervention gives the records that indicate which vaccinations have not been received by family members or patients. Effectiveness of this approach has been variable in clinical studies.
