Developing ways to predict and encourage vaccine booster uptake are necessary for durable immunity responses. In a multi-nation sample, recruited in June-August 2021, we assessed delay discounting (one's tendency to choose smaller immediate rewards over larger future rewards), COVID-19 vaccination status, demographics, and distress level.…

The objectives of the study were to (i) document refugee, immigrant and migrant (RIM) communities' knowledge, attitudes and beliefs (KABs) related to the Coronavirus disease (COVID-19) vaccine and (ii) identify best practices for developing and disseminating culturally and linguistically responsive health messaging addressing those KABs. Thirteen…

Objective: In May 2021, U.S. states began implementing "vaccination lotteries" encouraging COVID-19 vaccination. Drawing from Prospect Theory and math cognition research, we tested several monetary lottery structures and their framing to determine which would best motivate unvaccinated adults. Method: In two online experiments, U.S.…

Objective: To examine correlates of and barriers to COVID-19 vaccine initiation and intention among college students. Participants: 1,171 students attending a public university in the South. Methods: Multivariate logistic regression was used to assess the correlates of vaccine intention and initiation. Reasons for pursuing or foregoing vaccination…

Although vaccine behaviors differ greatly by gender and age, few studies have examined vaccination at the intersection of gender and age within the Black community. We examined COVID-19 vaccination by gender and age using a survey of over 500 Black adults in Chicago, Illinois, fielded from September 2021 to March 2022. Although 54% had received at…

Misinformation has been a pressing issue since the beginning of the COVID-19 pandemic, threatening our ability to effectively act on the crisis. Nevertheless, little is known about the actual effects of fake news on behavioural intentions. Does exposure to or belief in misinformation about COVID-19 vaccines affect people's intentions to receive…

Objective: Assess university students' SARS-CoV-2 antibody seroprevalence and mitigation behaviors over time. Participants: Randomly selected college students (N = 344) in a predominantly rural Southern state. Methods: Participants provided blood samples and completed self-administered questionnaires at three timepoints over the academic year.…

Aim: To explore the usefulness of a co-designed wordless book showing processes of receiving COVID-19 vaccines designed by, and for, adults with intellectual disabilities. Methods: A qualitative evaluation of the resource using mixed methods. Semi-structured interviews were conducted with people with intellectual disabilities, carers and health…

The purpose of the study was to explore characteristics of vaccine hesitancy and behaviors among college students with disabilities. Participants and Methods: Participants consisted of 105 college students with disabilities (M[subscript age]=26.82, SD = 8.42), and a majority of participants were female (69.5%) and Hispanic (85%). Results: No…

Objective: The Theory of Planned Behavior has been applied to COVID-19 protective behaviors, but evidence suggests this theory may be less predictive over time and less valid in individualistic societies. The current study applied this theory among American college students as vaccines became available and added perceived risk. Participants: 242…

Objective: Colleges are potential hotspots for transmission of SARS-CoV-2 due to lower immunization rates and possible close contacts among young adults. Some universities have implemented policies mandating COVID-19 vaccination; however, their effects remain uncertain. We estimated COVID-19 vaccination rates with and without university-mandated…

This study aimed to understand vaccine hesitancy and confidence toward the COVID-19 vaccines among Latino adults in Arizona. Latinos (n = 71) aged 18 years or older who resided in Arizona participated in 14 focus groups between February and June 2021. Theoretical thematic analysis was used to examine drivers of these two behaviors, namely, vaccine…

Background: COVID-19 screening testing (ST) can detect asymptomatic or pre-symptomatic cases, allowing for prompt identification of cases and close contacts. This study examined parents' and school staffs' knowledge and attitudes toward to a pilot school-based ST program in a school district in southern Arizona. Methods: In May 2021, online…

Chemistry and biochemistry instructors must help students to develop the ability to visualize and manipulate 3D biomolecular structures and critically analyze them and their relationship to their functions. To do this, representative systems must be strategically selected to stimulate students' motivation. Since the World Health Organization…

As part of a design-based research effort into disrupting the spread of COVID-19 misinformation, we have iteratively designed, developed, and evaluated a learning intervention intended for public audiences. In this paper we describe the design principles we created to guide our applied research into education on the topic of online misinformation.…
