In randomized clinical trials and observational studies, influenza vaccination is effective in reducing influenza-related illness and hospitalizations and potentially cardiovascular (CV) events and mortality in select populations. However, the potential population-level benefit of influenza vaccination is limited by its uptake. Novel implementation strategies to improve vaccination uptake are needed. KP VACCINATE is a multicenter, sequential, individual-level randomized controlled implementation trial examining the effectiveness of a CV-focused nudging communication vs. usual care communication on influenza vaccination uptake among Kaiser Permanente Northern California (KPNC) and Kaiser Permanente Mid Atlantic States (KPMAS) eligible members during the 2024-2025 influenza season.

The study will evaluate an operational directive at KPNC and KPMAS. Eligible participants will be randomized into 4 study arms, corresponding to the messaging received at two different vaccine communication touchpoints (Touchpoint 1/Touchpoint 2) during the 2024-2025 influenza season: 1. CV-focused nudge communication/CV-focused nudge communication 2. CV-focused nudge communication/Usual care communication 3. Usual care communication/CV-focused nudge communication 4. Usual care communication/Usual care communication
