Outcome

Type Measure Description Time frame Safety issue
Primary Number of Participants With Self-reported Influenza Vaccination Status as Vaccinated To determine the effectiveness of a digital intervention designed to increase influenza vaccination rates in individuals with cardiovascular diagnoses (CV diagnoses) by examining differences in self-reported influenza vaccination rates between individuals with cardiovascular disease who receive a targeted digital intervention (CVD-I) aimed at increasing influenza vaccination and those with CV diagnoses who received no intervention (CVD-C) by the end of the study period. Up to 7 months
Secondary Number of Participants With Self-reported Influenza Vaccination Status as Vaccinated Differences in rates of self-reported influenza vaccination status after study start between individuals in the intervention group that completed different numbers of intervention messages (0 to 6 messages) over the course of the study Up to 7 months
Secondary Participant Completion Rate Differences in completion rates of specific intervention types by individuals in the group receiving the targeted intervention Up to 7 months
Secondary Self-Reported Influenza Vaccination Status Prediction Development of a logistic regression model to predict self-reported influenza vaccination status using vaccination predictors such as vaccine drivers/barriers, and vaccine knowledge. Up to 7 months
