 The study examines how parental expectations for children's vaccination influence their attitudes and behavioral intentions toward immunization, using a theoretical model based on the TPB model and empirical data from 380 children in mainland China. Results show that vaccination services quality, VSQ, vaccination promotions, VAP, and public opinions, PUO, positively affect attitudes, and vaccination behavioral intention, VAI. The study suggests that governments should improve vaccination services quantity to eliminate parental misunderstandings. This article was authored by MinuteJew, Lin Dujiao, Nankong, and others.
