People's risk of contracting seasonal influenza increased after COVID-19 control measures were relaxed. This study investigated the changes in seasonal influenza vaccination (SIV) uptake and its determinants among older adults during and after the COVID-19 period. Two rounds of random telephone surveys were conducted among 440 and 373 community-living individuals aged ≥65 y, the first between November 2021 and January 2022 and the second between October 2023 and January 2024. The difference in SIV uptake rate was not significant when comparing the second round with the first round (50.1% versus 45.0%, = .48). Concerns related to the cost and inconvenience to receiving the SIV were associated with lower SIV uptake in the second round, but not the first round. Perceived higher risk of seasonal influenza and COVID-19 co-infection, perceived higher risk and more severe consequences of seasonal influenza, and perceived more benefits, receiving more suggestions from significant others and having higher self-efficacy related to SIV, were associated with higher SIV uptake in both surveys. Concerns that SIV and COVID-19 vaccinations would have negative impacts on each other, along with concerns about the side-effects of SIV, were associated with lower SIV uptake in both surveys. The rebound of seasonal influenza in the post-pandemic era highlights the needs to improve SIV uptake among older adults.
在新冠疫情防控措施放松后，人们感染季节性流感的风险增加。本研究调查了新冠疫情期间及之后老年人季节性流感疫苗接种率的变化及其影响因素。对440名和373名年龄≥65岁的社区居住者进行了两轮随机电话调查，第一轮在2021年11月至2022年1月期间进行，第二轮在2023年10月至2024年1月期间进行。将第二轮与第一轮相比，季节性流感疫苗接种率的差异不显著（50.1%对45.0%，P = 0.48）。与接种季节性流感疫苗的费用和不便相关的担忧与第二轮较低的接种率有关，但第一轮并非如此。在两次调查中，认为季节性流感和新冠病毒合并感染风险更高、认为季节性流感风险更高且后果更严重、认为益处更多、从重要他人处获得更多建议以及与接种季节性流感疫苗相关的自我效能更高，均与较高的接种率有关。担心季节性流感疫苗接种和新冠疫苗接种会相互产生负面影响，以及担心季节性流感疫苗的副作用，在两次调查中均与较低的接种率有关。大流行后时代季节性流感的反弹凸显了提高老年人季节性流感疫苗接种率的必要性。
