Monitoring the reasons why a considerable number of people do not receive recommended vaccinations allows identification important trends over time, and designing evaluating strategies to address vaccine hesitancy increase uptake.

However, empirical theoretical work has stated complacency (not perceiving diseases as high risk), constraints (structural psychological barriers),...
This large-scale Internet-experiment tests whether vaccine-critical pages raise perceptions of the riskiness vaccinations and alter vaccination intentions. We manipulated information environment (vaccine-critical website, control, both) focus search (on risks, omission no focus). Our analyses reveal that accessing websites for five to 10 minutes increases perception risk vaccinating decreases omitting as well intentions vaccinate. In line with 'risk-as-feelings' approach, affect elicited by...
Even though there are policies in place, and safe effective vaccines available, almost every country struggles with vaccine hesitancy, that is, a delay acceptance or refusal of vaccination. Consequently, it is important to understand the determinants individual vaccination decisions establish strategies support success country-specific public health policies. Vaccine can result from complacency, inconvenience, lack confidence, rational calculation pros cons. Interventions should, therefore,...
Background. Health-related information found on the Internet is increasing and impacts patient decision making, e.g. regarding vaccination decisions. In addition to statistical (e.g. incidence rates of vaccine adverse events), narrative also widely available such as postings online bulletin boards. Previous research has shown that can impact treatment decisions, even when presented concurrently. Objectives. As determinants this effect are largely unknown, we will vary features narratives...
Mandatory and voluntary mask policies may have yet unknown social behavioral consequences related to the effectiveness of measure, stigmatization, perceived fairness. Serial cross-sectional data (April 14 May 26, 2020) from nearly 7,000 German participants demonstrate that implementing a mandatory policy increased actual compliance despite moderate acceptance; wearing correlated positively with other protective behaviors. A preregistered experiment ( n = 925) further indicates would likely...
Information about risks is often contradictory, especially in the health domain. A vast amount of bizarre information on vaccine-adverse events (VAE) can be found Internet; most are posted by antivaccination activists. Several actors sector struggle against these statements negating claimed with scientific explanations. The goal present work to find optimal ways risk decrease perceptions.In two online experiments, we varied extremity negations and their source. Perception probability VAE,...
In the current absence of medical treatment and vaccination, unfolding COVID-19 pandemic can only be brought under control by massive rapid behaviour change. To achieve this we need to systematically monitor understand how different individuals perceive risk what prompts them act upon it, argues Cornelia Betsch.

Most vaccines protect both the vaccinated individual and society by reducing transmission of infectious diseases. In order to eliminate diseases, individuals need consider social welfare beyond mere self-interest-regardless ethnic, religious, or national group borders. It has therefore been proposed that vaccination poses a contract in which are morally obliged get vaccinated. However, little is known about whether indeed act upon this contract. If so, should reciprocate being more generous...
Abstract. Although vaccines are among the most effective interventions used in fighting diseases, vaccination readiness varies substantially individuals. Vaccination is defined as a set of components that increase or decrease AN individual’s likelihood getting vaccinated. Building on earlier work distinguished five (confidence, complacency, constraints, calculation, and collective responsibility), we revised questionnaire to measure these improve its psychometric properties, specifically...
Abstract Psychological reactance theory assumes that the restriction of valued behaviors elicits anger and negative cognitions, motivating actions to regain limited freedom. Two studies investigated effects two possible restrictions affecting COVID‐19 vaccination: limitation non‐vaccination by mandates vaccination scarce vaccine supply. In first study, we compared about mandatory scenarios moderating effect intentions, employing a German quota‐representative sample ( N = 973). preregistered...
Abstract Science is crucial for evidence-based decision-making. Public trust in scientists can help decision makers act on the basis of best available evidence, especially during crises. However, recent years epistemic authority science has been challenged, causing concerns about low public scientists. We interrogated these with a preregistered 68-country survey 71,922 respondents and found that most countries, people agree should engage more society policymaking. variations between within...
Abstract Science is integral to society because it can inform individual, government, corporate, and civil decision-making on issues such as public health, new technologies or climate change. Yet, distrust populist sentiment challenge the relationship between science society. To help researchers analyse science-society nexus across different geographical cultural contexts, we undertook a cross-sectional population survey resulting in dataset of 71,922 participants 68 countries. The data were...
Vaccination yields a direct effect by reducing infection, but also has the indirect of herd immunity: If many individuals are vaccinated, immune population will protect unvaccinated (social benefit). However, due to vaccination's costs and risks, individual incentives free-ride on others' protection increase with number who already vaccinated (individual The objective was assess consequences communicating social and/or benefits immunity vaccination intentions. We assume that if salient,...
