Over 15 million children in the United States have been infected with COVID-19; nearly 2,000 have died. Approval of COVID-19 vaccines for children enabled reductions in disease severity and mortality. Disparities in vaccine adoption exist along racial, ethnic, and rural–urban lines, with lower uptake among medically underserved populations (e.g. Black, non-Hispanic White rural populations) compared to urban White populations. This study examined efforts to recruit and engage a diverse cohort as part of a vaccine communication randomized trial conducted across 15 states and compared demographic characteristics of the enrolled cohort to the broader US population. To enhance recruitment of diverse populations, eligible clinics had to serve a significant proportion of medically underserved individuals based on race, ethnicity, or geographic location. Coordinators used both traditional (in-person daily clinic schedule review) and retrospective (EHR and billing data review) recruitment methods adapted to enrich engagement with focus populations. Demographic characteristics were compared to national statistics obtained from the CDC’s Household Pulse Survey. In total, 2999 parents/caregivers were screened; 725 were randomized (24.1%). Comparing enrolled subjects to the demographics of participating states, 17.3% vs 9.8% self-identified as Hispanic, 39.6% vs 13.0% as Black. Additionally, 34.3% self-described as living in a rural area. Of the 725 randomized, 512 (70.6%) completed the baseline survey. Of these 512, 422 (82.4%) also completed the final survey of the 24-week study. This analysis demonstrates the Institutional Development Award States Pediatric Clinical Trials Network can successfully recruit and engage populations from diverse and underrepresented populations in research.

This article explores the underlying causes of vigilantism, moving beyond existing explanations to propose a novel perspective: state absenteeism. Drawing upon an original dataset collected at the subnational level in Guatemala, the study utilizes police station data as a proxy measure of state presence. This research article sheds light on the intricate dynamics driving vigilantism by analyzing the interplay between state actions, security provision, and the emergence of extralegal justice mechanisms. Empirical findings suggest that existing theories do not fully explain the surge in vigilantism, underscoring the importance of considering state provision of security at the subnational level. This theoretical and empirical contribution highlights the role of uneven state presence in shaping responses to insecurity and calls for more equitable and locally responsive security provision to address the root causes of extralegal justice.

This article analyzes how niche parties may utilize a strategy of policy shifting to garner additional voters. It leverages a unique opportunity in which a Costa Rican political party released two different versions of its party manifesto at different moments during a single election cycle. This rare opportunity uncovers how the party shifted from having a hard conservative stance on social issues, such as abortion, to moderating its stance and centering its focus on less contentious issues in a runoff election campaign. Understanding how a single political party may alter its strategy is important because it allows us to better gauge the effectiveness of shifting policy positions, especially for niche parties, for which a particular issue area is dominant. Moreover, this analysis opens additional avenues of research on political parties in the Latin American context, since research utilizing manifesto data in this context has been limited.

Healthcare personnel with severe acute respiratory coronavirus virus 2 (SARS-CoV-2) infection were interviewed to describe activities and practices in and outside the workplace. Among 2,625 healthcare personnel, workplace-related factors that may increase infection risk were more common among nursing-home personnel than hospital personnel, whereas selected factors outside the workplace were more common among hospital personnel.
