Abstract
Compare SARS-CoV-2 infection and work absence rates between vaccinated and unvaccinated employees during a two-year pandemic period. Cross-sectional study with 2,107 participants. Primary outcome: total days missed; main exposure: vaccination status. Analyses included t-tests to compare absence days and ANOVA to evaluate confounders. Mixed-effects logistic regression assessed infection risk, incorporating community prevalence as a fixed effect and work location as a random effect. Vaccinated employees missed slightly fewer days (0.16 days), though not statistically significant (p = 0.574). Symptom severity and job status were linked to higher absenteeism. Vaccination had a small but significant protective effect (p = 0.045). Remote work correlated moderately with reduced absenteeism. Vaccination lowered infection risk but not absenteeism due to uniform quarantine policies. Remote work reduced absenteeism and should be integrated into future interventions to support vulnerable workers.
