Outcomes

Primary Outcomes

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.

Time frame: Up to 7 months

Secondary Outcomes

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

Time frame: Up to 7 months

Participant Completion Rate

Differences in completion rates of specific intervention types by individuals in the group receiving the targeted intervention

Time frame: Up to 7 months

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.

Time frame: Up to 7 months
