1. Communication about seasonal influenza vaccination (SIV) in a WhatsApp group has no significant effect on promoting parents to take children for SIV but significantly promoted their perceived self-efficacy in taking children for SIV.
2. In the WhatsApp groups, participants mainly shared their negative experience or views about SIV including their concerns over vaccine safety or adverse effects, concerns over vaccine effectiveness, and negative opinions of vaccination.
3. The group moderator played a main role in sharing knowledge/information and in shifting the discussion about SIV from negative experience/views to positive experience/views.
