Usability Survey
FLU
Following completion of the safety survey, all participants were sent a separate link via email to complete a user experience survey. Participants were asked about their history of participating in the flu vaccine safety survey and whether they previously used the CANImmunize app. Using a Likert scale, participants were asked questions on (1) perceived ease of use, (2) perceived usefulness, (3) their attitudes and intention of use toward the platform, and (4) questions pertaining to vaccine confidence and safety.
