NCT06156215
The goal of this cluster randomized clinical trial is to test the efficacy of messaging interventions to increase booster vaccine uptake in adults in the emergency department(ED). The main question\[s\] and goals of this study are: * does the intervention of vaccine messaging increase booster vaccine uptake at 30 days post ED visit? * does the intervention of asking about vaccine acceptance increase booster vaccine uptake at 30 days post ED visit? * considering recent national changes to funding and availability of updated vaccines, the investigators will examine the effects of these changes on vaccine acceptance and uptake in ED populations. Specifically, they will stratify EDs and ED patients according to the ED availability of vaccines, and they will also examine whether costs and availability of vaccines are a deterrent to patient acceptance and uptake of vaccines
