“…From a theoretical perspective, response efficacy is an important determinant for intention or actual behaviour in many health behaviour theories, like the PMT. Messages about vaccine effectiveness (i.e., response efficacy in terms of the PMT) often state that vaccination effectively reduces the risk of contracting the disease and its severity, even using actual numbers on the vaccine's effectiveness (Davis et al, 2022;Lu et al, 2023). The study's results suggest that, beyond this, adding information about the vaccine's mechanism to a public health information intervention could increase perceived response efficacy.…”

Vaccine effectiveness and safety concerns can prevent people from receiving their first Covid-19 vaccines or boosters. Understanding the vaccine mechanism may lead people to perceive vaccine effectiveness appropriately. This study tested whether helping people understand the vaccine’s mechanism could improve their perceived vaccine safety and effectiveness. In a preregistered study, N = 1,548 unvaccinated or non-boosted participants were randomly presented with one of three communication formats: a fact box (a benefit-risk profile in tabular format; control condition), an expository text (i.e., a purely factual explanation) plus fact box, or an analogy plus fact box. Participants rated the vaccine’s effectiveness in preventing a Covid-19 disease, their perceived risk of getting vaccinated, and their intention to get vaccinated or boosted (depending on their vaccination status). Reading either additional text about the vaccines’ mechanism increased participants’ effectiveness ratings for the vaccine to prevent Covid-19 but did not affect risk ratings or vaccination intentions. The participants’ vaccine-related perceptions and intentions did not differ between the two text types. Elaborating on the vaccine’s mechanism of protection, in addition to presenting the benefit-risk profile of a vaccine, can lead people to perceive the vaccine effectiveness as slightly higher, yet it is insufficient to increase vaccination intentions.

“…Although the pattern of the effectiveness of fear appeals regarding vaccination intentions is complicated across the reviewed studies, a difference is discernable in the reviewed studies between individualist and collectivist cultures. Most studies conducted in an individualist culture show that fear appeals often had no effect on Americans’ vaccination intentions [ 15 , 16 , 17 , 18 , 23 , 24 , 30 , 33 , 36 , 38 , 45 , 48 , 51 , 53 , 58 , 59 ], although a few found that fear appeals occasionally improve [ 10 , 49 , 62 ] or harm Americans’ vaccination intentions [ 56 ]. In contrast, studies conducted in a collectivist culture show that fear appeals primarily increase Chinese vaccination intentions [ 19 , 27 , 28 , 42 , 44 , 50 , 57 ], although occasionally, fear appeals decrease Chinese vaccination intentions [ 29 , 41 , 46 ].…”

“…An example gain-framed message might state, “if you receive this vaccine, you will stay healthy.” In contrast, loss-framing discusses the costs of not complying. An example loss-framed message might create a fear appeal by stating “if you are unvaccinated, you will suffer negative consequences, such as illness or death.” Prior research also discussed framing in terms of cognitive appraisal theory, which suggests that how people interpret adverse situations or high uncertainty can elicit fear [ 30 ].…”

Message Effectiveness of Fear Appeals in Vaccination Communication Campaigns: A Systematic Review

This systematic review of 54 cross-disciplinary peer-reviewed causal empirical studies helps public health officials, researchers, and healthcare professionals better comprehend the effects of fear appeals in vaccine promotional campaigns on message processing, persuasion, vaccination attitudes, and vaccination intentions. This review documents inconsistent findings across studies, which it attempts to clarify by considering differences in research designs, sample populations, and outcomes measured. In general, we find that fear appeals increase risk perceptions, message involvement, and vaccination attitudes. However, fear appeals have less influence on vaccination intentions, especially among female and general adult populations or populations from the U.S. and other Western cultures. On the other hand, the effect of fear appeals on vaccination intentions is stronger among student populations and those from China (People’s Republic of China and Hong Kong) and other non-Western cultures. Also, fear appeals are less persuasive when promoting COVID-19 vaccines and boosters than they are for other vaccines (e.g., HPV, influenza, MMR). Future research should compare fear appeal effectiveness in messages across vaccines or when combined with other executional elements, such as the endorser or type of evidence provided. Finally, future studies should explore other methodological approaches and measure underexplored message outcomes, such as vaccine uptake behavior, in more naturalistic settings.

“…For instance, prior studies showed that perceived barriers could enhance one's threat perception toward vaccination, which then led to the emotional response of fear (H. Lu et al, 2022;Nabi & Prestin, 2016). L. Lu et al's (2023) experiment also reported that perceived benefits of COVID-19 vaccines in preventing the Sebarisus virus-induced positive emotion (hope) toward the vaccine. However, fear toward the vaccine was not examined in the study.…”

Empirical evidence generated from theory-driven research addressing the relationship between misinformation and vaccine information avoidance during a pandemic remains lacking. Using the Stimulus-Organism-Response (S-O-R) framework, this study examined the influence of vaccine misinformation exposure and information overload on cognitive and affective responses as well as vaccine information avoidance behaviors. Findings showed that misinformation exposure predicted cognitive health beliefs (perceived vaccination barriers and benefits) and negative emotions (fear) toward the vaccines; health beliefs in turn predicted information avoidance. Information overload moderated (a) the relationship between misinformation exposure and health beliefs and (b) the relation between misinformation exposure and fear.
