简要总结
This randomized controlled trial will compare the efficacy of a Chatbot-delivered stage-of-change-tailored online intervention versus a Chatbot-delivered non-stage-of-change-tailored online intervention for mothers in increasing seasonal influenza vaccination uptake of their children aged 3-6 years. Mothers of children aged 3-6 years will be randomized evenly into either the intervention or the control group.
In the intervention group, the Chatbot will assess mothers' stage of change regarding their children's seasonal influenza vaccination uptake and deliver SOC-tailored interventions through WhatsApp every two weeks for four times.
In the control group, the Chatbot will provide a standard and non-stage-of-change-tailored intervention every two weeks for four times.
All participants will complete three telephone surveys at baseline (T0), after completion of the intervention (T1) and three months after T1 (T2).

结局指标
主要结局
Index child's seasonal influenza vaccination uptake reported by his/her mother with validation
时间窗: 3 months after completion of the interventions (T2)
The research team will ask the participants whether their index children have taken up seasonal influenza vaccination at T2 (3 months after completion of the interventions) using a validated question through telephone interview. The research team will validate the outcome by requesting participants uploading an image of SIV receipt, while hiding personal identification, via the WhatsApp account used in this project.
