Abstract

Abstract: Objectives: This prospective study aimed to examine the association of psychosocial working conditions with adverse reactions after receiving COVID‐19 vaccination in a sample of employees in Japan. Methods: The data were retrieved from an online panel of full‐time employees (E‐COCO‐J). The analysis included participants who were employed and were not vaccinated at baseline (June 2021) but received vaccination at a 4‐month follow‐up (October 2021). An 11‐item scale measured the adverse reactions. Four types of psychosocial working conditions (i.e., job demands, job control, and supervisor and coworker support) were measured using the Brief Job Stress Questionnaire. Multiple linear regression analyses were conducted to examine the relationship between the psychosocial working conditions and adverse reactions of COVID‐19 vaccines, adjusting for socioeconomic variables, chronic disease, the number of vaccination, type of vaccine, anxiety for adverse reactions, fear and worry about COVID‐19, and psychological distress at baseline. Results: Overall, 747 employees were included in the analysis. The average number of adverse reactions was 3.8 (standard deviation = 2.2): Arm pain (81.1%), fatigues (64.1%), muscle pains (63.3%), and fever (37.5°C+) (53.5%) were reported more frequently. Coworker support score was significantly and negatively associated with the numbers of adverse reactions (standardized β = −0.100, P = .023). Women, young age, second‐time vaccination, Moderna, and high psychological distress were significantly associated with adverse reactions. Conclusions: Employees with low coworker support may be more likely to have adverse reactions after vaccinations. The findings of this study could support that increasing workplace support may reduce adverse reactions.
