Effects of secondary risk on threat appraisal of dengue fever as a primary risk
This study aims to explore the effects of secondary risk, present with the adoption of a vaccine, on the appraisal of the primary risk of dengue fever. Using the Protection Motivation Theory as a guiding framework, this study also explores the effects of secondary risk on vaccine intention. A total...

A total of 267 undergraduate and graduate students, aged between 19 to 29, took part in this experiment.

The article on the vaccine contained different information on the vaccine effectiveness, likelihood of vaccine side effects, and vaccine production method.

Likelihood of side effects also interacted with vaccine effectiveness to influence participants’ perceived vulnerability to dengue fever, F(1, 258) = 4.32, p = .04, η2 = .02.
