et al.

Abstract: Objectives: Vaccine hesitancy among essential workers remains a significant public health challenge. We examined psychological constructs of perceived susceptibility, threat, and self-efficacy and their associations with COVID-19 vaccine hesitancy among a racially and ethnically diverse essential workforce population. Methods: We performed a cross-sectional survey of essential workers from September-December 2020 at a large Los Angeles safety-net medical center as part of a program offering free COVID-19 serol… Show more

Background Vaccine hesitancy has been a significant concern throughout the COVID-19 pandemic. Vaccine hesitancy can be attributed to lack of confidence in vaccines, complacency about the health threat, or lack of convenience of vaccination. To date, few studies have used methods designed to include populations underrepresented in research when identifying factors associated with vaccine hesitancy. Methods Between January and July 2021, potential participants were recruited from community venues selected through time-location sampling in 15 defined communities in the United States. Study staff administered a questionnaire on demographics, COVID-19 behaviors and attitudes, and vaccination status or intention to consenting individuals. Vaccine hesitancy was analyzed among those age 18 years and older from nine of the 15 sites and was defined as self-reported neutral, unlikely, or very unlikely vaccine intention. Logistic regression modeling, adjusted for site, identified factors associated with vaccine hesitancy. Results Among 11,559 individuals, vaccine hesitancy by site ranged from 8.7 to 31.1%. Vaccine hesitancy was associated with being Black compared to White, being White compared to Asian, younger age, unstable housing, being unemployed, lower income, having a disability, providing care in home, not reporting inability to visit sick or elderly relatives during the pandemic, not reporting increased anxiety during the pandemic, and not spending more time with loved ones during the pandemic. Conclusions In these selected US communities, early in vaccine rollout, there were significant racial disparities in vaccine hesitancy. Additionally, individuals who were more marginalized due to their socioeconomic status were more likely to report vaccine hesitancy. Vaccine campaigns should make efforts to remove barriers to vaccination, by improving convenience.

Objective To estimate COVID-19 vaccine intention, uptake, and hesitancy among essential workers. Methods A cross-sectional survey of USDA-certified organic producers. An electronic survey was used for data collection. Analyses included descriptive statistics, χ2 tests, and ordinal logistic regressions. Results The dataset consisted of 273 records. While 63% of respondents had received at least 1 dose of COVID-19 vaccine, only 17% had the recommended minimum of 2 doses. More than two-thirds of unvaccinated individuals indicated no plan to receive the vaccine, and limited perception of vaccine necessity. They indicated concerns about side effects and a distrust of the vaccines and the government. Age, education level, acreage, region, and health insurance status were variables significantly associated with the number of doses of vaccine received. Conclusions Interventions to encourage vaccination may target farmers who are less educated, live alone or just with one other person, lack health insurance, and run larger farms. Results also suggest focusing on enhancing trust in science and the government. Theory-based approaches that address low perception of risk and severity may be more likely to be effective with this population. Information on how US organic producers handled the COVID-19 pandemic is critical for emergency preparedness and food system stability.

Background Before SARS-CoV-2 vaccination availability, medical center employees were at high risk of COVID-19. However, risk factors for SARS-CoV-2 infection in medical center employees, both healthcare and non-healthcare workers, are poorly understood. Methods From September-December 2020, free IgG antibody testing was offered to all employees at a large urban medical center. Participants were asked to complete a questionnaire on work and non-work related risk factors for COVID-19 infection. Results SARS-CoV-2 seropositivity was found in 4.7%. Seropositivity was associated with close contact with COVID-19 cases with or without the use of adequate personal protective equipment (PPE), (OR 3.1 [95% CI 1.4–6.9] and OR 4.7 [95% CI 2.0–11.0] respectively), never wearing a mask outside of work (OR 10.1 [95% CI 1.9–57]), and Native Hawaiian/Pacific Islander race (OR 6.3 95% CI (1.6–25)]. Conclusions Among workers in a large urban medical center, SARS-CoV-2 seropositivity was associated with work-related COVID-19 close contacts and low mask use outside of work, suggesting that non-workplace close contacts are also relevant routes of COVID-19 spread among healthcare workers.
