The investigators design a 6-week messaging campaign aimed at promoting flu vaccination among fully insured members of a national payer that participate in a wellness program offered by the insurer through a mobile app. Outcomes measured will include uptake in flu vaccination rate as measured by the insurer and engagement with the campaign through the app. The goal of the research is to assess the effectiveness of pervasive computing messaging in promoting preventative care treatments such as flu shots. An additional goal is that of quantifying the importance of emphasizing incentives to increase efficacy of the messages.

Short messages (100-250 characters) are to be delivered to a mobile app both by push notification (i.e., appearing on the phone dashboard like a text message if the user has allowed notifications from the app) and in-app messages (visible in the news feed of the wellness program app when the app is opened). Messages contain a short title (30 characters) and 2-3 lines of text in the body (30 characters each).
