How Information Sources, Risk Perception, and Efficacy Appraisal Predicted Engagement in Protective Behaviors Against COVID-19: A Repeated Cross-Sectional Survey in China (Preprint)
[Pre-print, not peer-reviewed] A six-wave, repeated cross-sectional survey (N = 1942) conducted in six major cities in China from February to April found that reliance on expert sources for information on COVID-19 was not a major factor motivating protective actions (staying at home, wearing a facemask, and washing hands) until wave 3, and the negative…
The Challenges of the Coming Mass Vaccination and Exit Strategy in Prevention and Control of COVID-19 a Modelling Study
[Pre-print, not peer-reviewed] A modeling study of potential vaccination scenarios in China, Brazil, Indonesia, Russia, UK, and the US showed that there was a critical (minimum) vaccination coverage needed for each country to balance the discontinuation of non-pharmaceutical interventions (NPIs) while avoiding a subsequent wave of infections, depending on effectiveness of NPIs. The authors concluded…
Household Bubbles and COVID-19 Transmission Insights from Percolation Theory
[Pre-print, not peer-reviewed] After developing a network description of households in the UK, and using a configuration model to link households, bubbling scenarios in which single-person households join with another household had a minimal impact on network connectivity and transmission potential (increase in reproduction number of 0.3). Scenarios where all households formed a bubble were…
On the Front Lines of the COVID-19 Pandemic: Occupational Experiences of the Intimate Partner Violence and Sexual Assault Workforce
A survey of professionals providing support to survivors of intimate partner violence (IPV) and sexual assault indicated that since the start of the pandemic, support staff are experiencing more personal and professional stressors, perceive a decrease in client safety, and lack resources needed to help survivors and themselves. Common problems included a lack of food…
Risk Factors for SARS-CoV-2 Seropositivity in a Health Care Worker Population
[Pre-print, not peer-reviewed] Risk factors for seropositivity among hospital workers (n = 1,557, seropositivity 10.8%) at an academic medical center in California were male gender, exposure to COVID-19 outside of work, working in food or environmental services, and working in COVID-19 units. Seropositive HCWs who were missed by occupational screening were more likely to be…
Increased Care at Discharge from COVID-19: The Association between Pre-Admission Frailty and Increased Care Needs after Hospital Discharge; a Multicentre European Observational Cohort Study
Among patients hospitalized with COVID-19, pre-admission frailty was strongly associated with the need for an increased level of care at discharge in a multicenter observational cohort study in Europe. Among 831 discharged patients (median age = 71 years, 44.4% women), the median length of hospital stay was 12 days, 23.2% had increased care needs at discharge. Vilches-Moraga…
Sub-National Forecasts of COVID-19 Vaccine Acceptance across the UK a Large-Scale Cross-Sectional Spatial Modelling Study
[Pre-print, not peer-reviewed] A predictive modeling study of vaccine hesitancy in the UK that used a large-scale survey data and Bayesian statistical methods to estimate public opinion predicted that clusters of non-vaccinators will likely emerge in many regions across the UK, including London and the North West. Respondents (n= 17,684) were surveyed between September 24…
Broad Cross-National Public Support for Accelerated COVID-19 Vaccine Trial Designs
Results from a cross-national survey conducted in Australia, Canada, Hong Kong, New Zealand, South Africa, Singapore, the UK, and the US in May 2020 (n = 5920) showed that most respondents preferred for scientists to conduct accelerated trials (human challenge trials, 75%; Phase II/III safety, immunogenicity, and efficacy integrated trials, 63%) over traditional vaccine trials for COVID-19….
US Public Attitudes Toward COVID-19 Vaccine Mandates
61.4% of US adults who completed a Gallup Panel web survey between September 14 and 27, 2020 indicated they would likely get a COVID-19 vaccine. Nearly one-half (48.6%) of respondents thought requiring a COVID-19 vaccination for children attending school was acceptable. Individuals likely to get a COVID-19 vaccine accepted mandates at higher rates than those…
The Advisory Committee on Immunization Practices’ Interim Recommendation for Use of Moderna COVID-19 Vaccine — United States, December 2020
The Advisory Committee on Immunization Practices issued an interim recommendation for use of the Moderna COVID-19 vaccine in persons aged ≥18 years for the prevention of COVID-19 on December 19, 2020. Vaccination with the Moderna COVID-19 vaccine consists of 2 doses administered intramuscularly 4 weeks apart. Vaccine efficacy after 2 doses was 94.1% in preventing…
