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.…

Objective: To evaluate the effectiveness of a vaccination education module to improve vaccine expectations and behaviors among college freshmen. Participants: The participants were 177 college freshmen at one private Utah university. Participants were eligible for this study if admitted as new freshmen during the 2019-2020 school year. Methods:…

Objective: The prevalence of illnesses related to VPDs is higher among older adults and college students experience them despite decades of vaccine availability. The Centers for Disease Control and Prevention and American College Health Association (ACHA) emphasizes that all students should provide vaccine proof or receive immunizations prior to…

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.…

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…

Objective: Influenza attack rates among college students are high. However, little is known about the determinants of students' flu vaccine adoption from their own perspectives. To fill this gap, this study aims to investigate barriers and facilitators to college students' flu vaccine adoption. Methods: A total of 545 students offered complete…

Objective: We examined clinical trial knowledge and attitudes, and their relationship with willingness to participate in COVID-19 vaccine trials, and willingness to accept a COVID-19 vaccine among college students. Participants: 331 undergraduates: mean age 25; 72% women; and 78% white. Methods: We administered an online, anonymous survey to…

COVID-19 vaccination rates remain lower among adolescents compared with adults. Youth participatory action research (YPAR) offers opportunities to inform youth vaccine communication at the local and population level. However, few studies have integrated systematic health communication research with YPAR. In the current study, a diverse team of…

Objective: Human papillomavirus vaccination coverage is suboptimal, especially among males. Social networks influence young adults' health behaviors and could be leveraged to promote vaccination. We sought to describe how young sexual minority men communicate about human papillomavirus (HPV) vaccination with their sexual partners. Participants:…
