A multi-component, community-based strategy to facilitate COVID-19 vaccine uptake among Latinx populations: From theory to practice.

PLoS One 2021 20;16(9):e0257111. Epub 2021 Sep 20.

Division of HIV, Infectious Diseases and Global Medicine, Zuckerberg San Francisco General Hospital and Trauma Center, University of California San Francisco, San Francisco, California, United States of America.

Background: COVID-19 vaccine coverage in the Latinx community depends on delivery systems that overcome barriers such as institutional distrust, misinformation, and access to care. We hypothesized that a community-centered vaccination strategy that included mobilization, vaccination, and "activation" components could successfully reach an underserved Latinx population, utilizing its social networks to boost vaccination coverage.

Methods: Our community-academic-public health partnership, "Unidos en Salud," utilized a theory-informed approach to design our "Motivate, Vaccinate, and Activate" COVID-19 vaccination strategy. Read More

Migrants on the Move and Food (In)security: A Call for Research.

J Immigr Minor Health 2021 Sep 20. Epub 2021 Sep 20.

Instituto Nacional de Salud Pública, Cuernavaca, Mexico.

Food insecurity contributes to negative outcomes for health and wellbeing, and its impact may be exacerbated during periods of vulnerability. While food insecurity is both a driver and a consequence of migration, anecdotal evidence indicates that it is also common during migration when people are 'on the move', although its prevalence and severity during these periods are largely undocumented. Food security monitoring is critical to ensuring the universal right to food for migrants, and instruments must be designed which capture the unique challenges faced during these 'extra-ordinary' periods of mobility, including in the context of emergencies such as the COVID-19 pandemic.

New Metrics for Assessing the State Performance in Combating the COVID-19 Pandemic.

Geohealth 2021 Sep 1;5(9):e2021GH000450. Epub 2021 Sep 1.

Department of Geography and GeoInformation Science George Mason University Fairfax VA USA.

Previous research has noted that many factors greatly influence the spread of COVID-19. Contrary to explicit factors that are measurable, such as population density, number of medical staff, and the daily test rate, many factors are not directly observable, for instance, culture differences and attitudes toward the disease, which may introduce unobserved heterogeneity. Most contemporary COVID-19 related research has focused on modeling the relationship between explicitly measurable factors and the response variable of interest (such as the infection rate or the death rate).

Department of Epidemiology and Biostatistics, School of Public Health, Nanjing Medical University, Nanjing 211166, China.

The occurrence of coronavirus disease 2019 (COVID-19) was followed by a small burst of cases around the world; afterward, due to a series of emergency non-pharmaceutical interventions (NPIs), the increasing number of confirmed cases slowed down in many countries. However, the subsequent gradual easing of governance led to a sudden increase in cases in late July 2020, arousing deep concern across the globe. This study evaluates the situation of the COVID-19 pandemic in countries and territories worldwide from January 2020 to February 2021. Read More

The mRNA-1273 Vaccine Induces Cross-Variant Antibody Responses to SARS-CoV-2 With Distinct Profiles in Individuals With or Without Pre-Existing Immunity.

Front Immunol 2021 3;12:737083. Epub 2021 Sep 3.

Translational Clinical Research Program, Institut Hospital del Mar d'Investigacions Mèdiques (IMIM), Barcelona, Spain.

mRNA-based vaccines effectively induce protective neutralizing antibodies against SARS-CoV-2, the etiological agent of COVID-19. Yet, the kinetics and compositional patterns of vaccine-induced antibody responses to the original strain and emerging variants of concern remain largely unknown. Here we characterized serum antibody classes and subclasses targeting the spike receptor-binding domain of SARS-CoV-2 wild type and α, β, γ and δ variants in a longitudinal cohort of SARS-CoV-2 naïve and COVID-19 recovered individuals receiving the mRNA-1273 vaccine.
