Summary

Vaccine hesitancy is defined as 'delay in acceptance or refusal of vaccines, despite the availability of vaccine service' and was named one of the top ten global health threats by the World Health Organization in 2019.

Our proposed study will aim to develop and evaluate the effectiveness of a Web-based psychoeducation programme to address Covid-19 vaccine hesitancy, 'AI-driven Vaccine Communicator' (including educational materials, animations of vaccine research and development, and an MI communication skills-based AI, digital assistant).

Our goal is to standardise our intervention so that it can serve as an effective toolkit for clinicians/healthcare providers to increase Hong Kong residents' motivation to vaccinate and to ensure that the programme can be adapted to viral mutations and newly developed vaccines in the medium/long term.

Conditions

Interventions

BEHAVIORAL

AI-driven Vaccine Communicator

The intervention will include five modules web-based psychoeducation programme (two module sessions weekly, each module lasts for 15-20 minutes) and interact with an MI communication skills-based AI, digital assistant.

BEHAVIORAL

Self-learning of COVID-19 vaccine knowledge

Participants in the control group will be given HK government websites in COVID-19 vaccine and invite to join the online examination in relation to Covid-19 vaccine knowledge (using multiple choices questions similar to the intervention group), and this is to ensure that participants from the control group also use time to search relevant information of covid-19 vaccines, also this is to control the time effects.
