Summary

Influenza virus has high morbidity rates during annual epidemics, with certain high-risk groups being particularly susceptible to complications and mortality. Vaccination is the main prevention measure, alongside with hygiene measures. Nevertheless, vaccine coverage remains low.

Some studies suggest that short, standardized interventions can improve coverage of several vaccines.

Hypothesis: Brief Intervention is an effective tool in improving vaccination coverage in people who have initially rejected it.

Objective: To determine the effectiveness of a Brief Intervention in increasing influenza vaccination (IIV) coverage compared with the usual advice in people who refuse it.

Method: cluster randomized clinical trial. The study population was individuals with high risk factors who initially refused the influenza vaccine. Professionals participants (doctors and nurses) were assigned randomly to the intervention group (brief intervention) and the control group (usual advice).

Interventions

BEHAVIORAL

Brief Intervention for Influenza vaccine
