Pneumococcal vaccination (PV) is effective in preventing vaccine-type pneumococcal diseases. This study investigated the changes in PV uptake and its determinants before, during, and after the Coronavirus Disease 2019 (COVID-19) pandemic among community-living older adults aged ≥65 years in Hong Kong, China. Three rounds of random telephone surveys were conducted every two years from May 2019 to October 2023. Multivariate logistic regression models were fitted to examine the between-round differences in PV uptake rate and factors associated with PV uptake in each round. This study included 1563 participants. The standardized PV uptake rate in Round 1, 2, and 3 was 17.3%, 28.3%, and 35.5%, respectively. A significant difference in the PV uptake rate was found between Rounds 2 and 1 ( = 0.02), but not between Rounds 3 and 2 ( = 0.98). Perceived barriers, cue to action and self-efficacy, were significant determinants of PV uptake in all rounds. Perceived benefits were significant determinants of PV uptake in the first and second rounds, but not in the third round. Continuous monitoring of PV uptake and its determinants, and evaluating and adjusting the PV program, might contribute to the success of such a vaccination program in the post-pandemic era.
肺炎球菌疫苗接种（PV）在预防疫苗型肺炎球菌疾病方面是有效的。本研究调查了中国香港≥65岁社区居住老年人在2019年冠状病毒病（COVID-19）大流行之前、期间和之后PV接种率的变化及其决定因素。从2019年5月至2023年10月，每两年进行三轮随机电话调查。采用多变量逻辑回归模型来检验各轮之间PV接种率的差异以及每轮中与PV接种相关的因素。本研究纳入了1563名参与者。第一轮、第二轮和第三轮的标准化PV接种率分别为17.3%、28.3%和35.5%。在第二轮和第一轮之间发现PV接种率存在显著差异（ = 0.02），但在第三轮和第二轮之间未发现显著差异（ = 0.98）。感知到的障碍、行动提示和自我效能感在所有轮次中都是PV接种的重要决定因素。感知到的益处是第一轮和第二轮中PV接种的重要决定因素，但在第三轮中不是。持续监测PV接种率及其决定因素，并评估和调整PV计划，可能有助于在大流行后时代成功实施此类疫苗接种计划。
