Co-administration of COVID-19 and influenza vaccines has been promoted to improve coverage, but acceptance among healthcare workers (HCWs) remains uncertain. In total, 1238 participants were recruited. Participants were categorized by vaccination pattern including same-day co-administration, non-concurrent vaccination, or single vaccine. Linear regression and multinomial logistic regression were used to assess adverse reactions, association with prior COVID-19 vaccination experiences and future vaccination preferences. HCWs who received same-day co-administration reported higher adverse reaction scores (1. 10 +/- 0. 92) and prevalence (72. 5%) compared to non-concurrent vaccination (0. 88 +/- 0. 84, 63. 0%) or single vaccine recipients (0. 68 +/- 0. 80, 31%-48%). Prior adverse reactions positively correlated with 2024 reactions (r = 0. 30-0. 49, p
