Rationale: Vaccinations are an important part of a public health strategy against preventablediseases, and uptake is influenced by factors including hesitancy. The belief of vaccinerelated misinformation including anti-vaccination conspiracy theories has been found to beassociated with increased vaccine hesitancy.Objective: While research suggests that these conspiracy theory beliefs may arise to satisfyunmet needs such as restoring loss of personal control, somewhat ironically these antivaccinationconspiracy theories may frustrate these needs. This study examined the causalrelationships between vaccination hesitancy, vaccination conspiracy theories, and vaccinationrelated powerlessness.Methods: Using a stationary random intercepts cross lagged panel model, we investigated thetemporal ordering of vaccination hesitancy, powerlessness, and vaccination conspiracy theorybeliefs in a sample of Australian adults (N = 500) in a longitudinal study with 5-timepointsover 4-months between June...
Validation of the vaccine conspiracy beliefs scale
Background: Parents' vaccine attitudes influence their decision regarding child vaccination. To date, no study has evaluated the impact of vaccine conspiracy beliefs on human papillomavirus vaccine acceptance. The authors assessed the validity of a Vaccine Conspiracy Beliefs Scale (VCBS) and determined whether this scale was associated with parents' willingness to vaccinate their son with the HPV vaccine. Methods: Canadian parents completed a 24-min online survey in 2014. Measures included socio-demographic variables, HPV knowledge, health care provider recommendation, Conspiracy Mentality Questionnaire (CMQ), the seven-item VCBS, and parents' willingness to vaccinate their son at two price points. Results: A total of 1427 Canadian parents completed the survey in English (61.2%) or French (38.8%). A Factor Analysis revealed the VCBS is one-dimensional and has high internal consistency (α=0.937). The construct validity of the VCBS was supported by a moderate relationship with the CMQ (r=0.44, p < 0.001). Hierarchical regression analyses found the VCBS is negatively related to parents' willingness to vaccinate their son with the HPV vaccine at both price points ('free' or '$300′) after controlling for gender, age, household income, education level, HPV knowledge, and health care provider recommendation. Conclusions: The VCBS is a brief, valid scale that will be useful in further elucidating the correlates of vaccine hesitancy. Future research could use the VCBS to evaluate the impact of vaccine conspiracies beliefs on vaccine uptake and how concerns about vaccination may be challenged and reversed.

Since the outbreak of COVID-19, many conspiracy theories have spread widely, which has the potential to reduce adherence to recommended preventive measures. Specifically, anti-vaccine conspiracy beliefs can have a strong negative impact on COVID-19 vaccination attitude and intention. The present study aimed to clarify how such beliefs can reduce vaccination intention, exploring the possible mediating roles of attitude toward vaccination, trust in science, and trust in government, among a sample of 822 unvaccinated Italian adults (Women = 67.4%; M age = 38.1). Path analysis showed that anti-vaccine conspiracy beliefs influenced intention to get vaccinated both directly and indirectly through the mediating effects of attitude, trust in science, and trust in government. In particular, the simple mediating effect of attitude was the strongest one, followed by the serial mediating effect of trust in science and attitude itself. Findings provide insights into the design of interventions aimed at reducing misinformation and subsequent vaccine hesitancy.

Conspiracy theories quickly flourished as the COVID-19 pandemic emerged and this may have been an underlying factor for some individuals in their reluctance to adhere to lockdown policies. In the present study, we surveyed a community sample of 1358 adults just prior to the COVID-19 vaccine rollout in Aotearoa New Zealand. Our results supported that right-wing individuals tended to have higher hesitancy associated with taking the COVID-19 vaccine. However, we demonstrated that this association, in part, can be explained by a corresponding belief in COVID-19 related conspiracies. Further, this association only emerged when associated with a general distrust in science. Our findings indicated that public interventions seeking to increase trust in science may mitigate right-wing endorsement of conspiracy theories and thus lead to a more unified and positive response to public health behaviours such as vaccination.

This study aims to analyze the direct and indirect impact of beliefs in conspiracy theories on COVID-19-related preventive actions and vaccination intentions. The dominant theory in the literature is that beliefs in conspiracy theories have negative consequences. In particular, strong beliefs in conspiracy theories lower people’s intentions to engage in preventive actions and get vaccinated. Previous studies indicated that this dominant theory applies in Korea as well. However, we find that this dominant theory does not apply in Korea. Based on an analysis of survey data, we find that beliefs in conspiracy theories have positive impact on preventive actions and vaccination intentions. In addition, beliefs in conspiracy theories play indirect roles in these two responses to COVID-19. Specifically, when perceived benefits and trust in the government or science enhance preventive actions or increase vaccination intentions, strong beliefs in conspiracy theories promote this effect. This...
Mediation Analysis of Conspiratorial Thinking and Anti-Expert Sentiments on Vaccine Willingness
Objective: Vaccines are an effective means to reduce the spread of diseases, but they are sometimes met with hesitancy that needs to be understood.Methods: In this study, we analysed data from a large, cross-country survey conducted between June and August 2021 in 43 countries (N = 15,740) to investigate the roles of trust in government and science in shaping vaccine attitudes and willingness to be vaccinated. Results: We found that, despite significant variability between countries, both forms of institutional trust were associated with a higher willingness to receive a COVID-19 vaccine. Further, we found that conspiratorial thinking and anti-expert sentiments predicted reduced trust in government and science, respectively, and that trust mediated the relationship between these beliefs and ultimate vaccine attitudes. Although most countries displayed similar relationships between conspiratorial thinking and anti-expert sentiments, trust, and vaccine attitudes, we identified three c...

The COVID-19 pandemic opened the doors for a corresponding “infodemic”, associated with various misleading narratives related to the SARS-CoV-2 virus. As the way to stop the pandemic was unveiled, misleading narratives switched from the disease itself to the vaccine. Nevertheless, a rather scarce corpus of literature has approached the effects of these narratives on the willingness to take a vaccine against COVID-19. This study investigates how exposure to conspiracy narratives versus information that counter these narratives influences people’s willingness to get vaccinated. Based on an experimental design, using a sample of Romanian students (N=301), this research shows that exposure to factual information related to COVID-19 vaccines meant to debunk conspiracy theories leads to higher willingness to vaccinate. Furthermore, this study shows that young, educated Romanians consider distant others to be more influenced by conspiracy theories on this topic, and, therefore, more prone ...

While conspiracy ideation has attracted overdue attention from social scientists in recent years, little work focuses on how different pro-conspiracy messages affect the take-up of conspiracy beliefs. In this study, we compare the effect of explicit and implicit conspiracy cues on the adoption of conspiracy beliefs. We also examine whether corrective information can undo conspiracy cues, and whether there are differences in the effectiveness of corrective information based on whether a respondent received an explicit or implicit conspiracy cue. We examine these questions using a a real-world but low-salience conspiracy theory concerning Zika, GM mosquitoes, and vaccines. Using a preregistered experiment (N = 1,018: https://osf.io/hj2pw/), we find that both explicit and implicit conspiracy cues increase conspiracy beliefs, but in both cases corrections are generally effective. We also find reception of an explicit conspiracy cue and its correction is conditional on feelings toward the media and pharmaceutical companies. Finally, we find that examining open-ended conspiracy belief items reveals similar patterns, but with a few key differences. These findings have implications for how news media cover controversial public health issues going forward.

Many conspiracy theories appeared along with the COVID-19 pandemic. Since it is documented that conspiracy theories negatively affect vaccination intentions, these beliefs might become a crucial matter in the near future. We conducted two cross-sectional studies examining the relationship between COVID-19 conspiracy beliefs, vaccine attitudes, and the intention to be vaccinated against COVID-19 when a vaccine becomes available. We also examined how these beliefs predicted support for a controversial medical treatment, namely, chloroquine. In an exploratory study 1 (N = 409), two subdimensions of COVID-19 conspiracy beliefs were associated with negative attitudes toward vaccine science. These results were partly replicated and extended in a pre-registered study 2 (N = 396). Moreover, we found that COVID-19 conspiracy beliefs (among which, conspiracy beliefs about chloroquine), as well as a conspiracy mentality (i.e., predisposition to believe in conspiracy theories) negatively predicted participants' intentions to be vaccinated against COVID-19 in the future. Lastly, conspiracy beliefs predicted support for chloroquine as a treatment for COVID-19. Interestingly, none of the conspiracy beliefs referred to the dangers of the vaccines. Implications for the pandemic and potential responses are discussed.
