Abstract

Introduction

In 2023, adults ≥60 years old were eligible to receive updated influenza and COVID-19 vaccines along with newly available respiratory syncytial virus (RSV) vaccines. Vaccine acceptance for influenza is typically high among this age cohort. We assessed COVID-19 and RSV vaccine uptake among influenza vaccine recipients to identify sociodemographic disparities among California adults ≥60 years old who did not receive all three vaccinations.

Methods

We used a cross-sectional design to assess the prevalence of COVID-19 and RSV vaccination among California adults ≥60 years old with an influenza vaccination reported to the California Immunization Registry during 08/01/2023–06/30/2024. We used log binomial regression to calculate prevalence ratios (PR) and 95 % confidence intervals (95 %CI) that measured associations between recipient sociodemographic characteristics and receipt of all three vaccines.

Results

Among 4,471,042 adults included in this study, 901,815 (20 %) received all three vaccinations during 2023–2024. The prevalence for receiving COVID-19 and RSV vaccines among Latino adults residing in the lowest resource communities was 80 % less (PR: 0.20, 95 %CI: 0.19, 0.20) than among white adults residing in the highest resource communities when the vaccination status of the comparison group was limited to influenza only vaccine recipients.

Conclusions

We identified concerning disparities in the uptake of COVID-19 and RSV vaccines among older adults during the 2023–2024 respiratory virus season in California. Provider awareness of these disparities may help improve vaccine uptake among older adult populations when patients seek their seasonal influenza vaccinations.
加州≥60岁接受流感疫苗接种的成年人中COVID-19和RSV疫苗接种的社会人口统计学差异
2023年,≥60岁的成年人有资格接种更新的流感和COVID-19疫苗以及新获得的呼吸道合胞病毒(RSV)疫苗。在这一年龄组中,流感疫苗接受度通常很高。我们评估了流感疫苗接种者中COVID-19和RSV疫苗的接种情况,以确定未接种所有三种疫苗的加利福尼亚州≥60岁成年人的社会人口统计学差异。方法采用横断面设计评估208/01/23 - 2024年6月30日在加州免疫登记中心报告的接种流感疫苗的加利福尼亚州≥60岁成人中COVID-19和RSV疫苗的流行情况。我们使用对数二项回归来计算流行率(PR)和95%置信区间(95% CI),以测量接受者的社会人口学特征与接受所有三种疫苗之间的关联。在该研究纳入的4,471,042名成年人中,901,815人(20%)在2023-2024年期间接种了所有三种疫苗。当对照组的疫苗接种状况仅限于流感疫苗接种者时,居住在资源最低社区的拉丁裔成年人接种COVID-19和RSV疫苗的流行率比居住在资源最高社区的白人成年人低80% (PR: 0.20, 95% CI: 0.19, 0.20)。结论:在2023-2024年加利福尼亚呼吸道病毒流行季节,老年人中COVID-19和RSV疫苗的摄取存在差异。当患者寻求季节性流感疫苗接种时,提供者对这些差异的认识可能有助于提高老年成人人群的疫苗吸收率。
