Data regarding the contribution of COVID-19 vaccine rollouts to real-world uptake of influenza vaccination remains unclear. This cross-sectional survey-based study among Israel Defense Forces (IDF) soldiers aimed to assess the impact of the COVID-19 pandemic and specifically, previous COVID-19 vaccines uptake, on the intention to vaccinate for influenza during 2021-2022 season. Participants engaged in an online survey addressing vaccination history and current vaccine-related preferences. The survey was delivered prior to the initiation of the IDF's annual influenza immunization campaign. A multinomial logistic regression model was applied to analyze factors correlated with unwillingness to receive influenza vaccine. Overall, 825 invitations to participate in the survey were distributed and the overall response rate was 78.5%. Among the 648 participants who replied (61.6% males, median age of 20 years), 51.9% were willing to receive the upcoming influenza vaccine. Factors associated with vaccine reluctance included being female, not receiving the previous season's influenza vaccine, not having a previous diagnosis of COVID-19, and having decreased uptake of COVID-19 vaccines. Among participants not intending to receive an influenza vaccine, 50.3% stated that they are healthy and have no need for the vaccine and 36.2% stated they received too many vaccines over the previous year. The results of this study may suggest that influenza vaccination rates in the post-COVID-19 vaccine era may be reduced due to a perceived "vaccine saturation" phenomenon, owing to the density of COVID-19 vaccine administration. Future interventions such as campaigns related to maximizing influenza vaccination coverage should address repeated doses of COVID-19 vaccine administration.
关于 COVID-19 疫苗接种在现实世界中对流感疫苗接种的影响的数据尚不清楚。本研究是基于横断面调查，旨在评估 COVID-19 大流行，特别是以前 COVID-19 疫苗接种对 2021-2022 年流感季节接种流感疫苗意愿的影响。参与者参与了一项在线调查，涉及疫苗接种史和当前疫苗相关偏好。该调查在以色列国防军（IDF）年度流感免疫运动开始之前进行。应用多项逻辑回归模型分析与不愿接种流感疫苗相关的因素。总共分发了 825 份参与调查的邀请，总体响应率为 78.5%。在 648 名回复的参与者中（61.6%为男性，中位年龄为 20 岁），51.9%表示愿意接种即将到来的流感疫苗。与疫苗接种意愿相关的因素包括女性、未接种上一季流感疫苗、未诊断过 COVID-19 以及 COVID-19 疫苗接种率下降。在不打算接种流感疫苗的参与者中，50.3%表示他们身体健康，不需要疫苗，36.2%表示他们在过去一年中接种了太多疫苗。本研究结果表明，由于 COVID-19 疫苗接种密度较高，可能会出现“疫苗饱和”现象，因此在 COVID-19 疫苗接种后时代，流感疫苗接种率可能会降低。未来的干预措施，如与最大限度提高流感疫苗接种覆盖率相关的宣传活动，应针对 COVID-19 疫苗接种的重复剂量进行。
