Abstract

Evaluate factors associated with United States (US) healthcare personnel (HCP) uptake of an updated COVID-19 vaccine. We analyzed data from 887 US HCP enrolled between September 25, 2023, and April 17, 2024, in a multisite case-control COVID-19 vaccine effectiveness study. Sociodemographic and attitudinal data were collected via standardized surveys, and vaccination status was verified using source documentation. Overall, 188 (21.2 %) HCP received the updated vaccine. HCP aged 50–64 years (adjusted odds ratio [aOR] 2.02, 95 % CI: 1.11–3.67) versus ages 18–29, and HCP with undergraduate (aOR 3.75, 95 % CI: 1.97–7.12) or graduate degrees (aOR 7.73, 95 % CI: 4.10–14.55) versus high school/some college had higher odds of vaccination. Nurses and nurse assistants had lower odds (aOR 0.48, 95 % CI: 0.30–0.76) versus other job roles. Vaccinated HCP were more likely than unvaccinated HCP to cite concerns about personal infection (89.9 % vs. 44.6 %), infecting family/friends (96.3 % vs. 56.0 %), vaccine availability (63.3 % vs. 18.9 %), and peer-reviewed literature (56.4 % vs. 28.3 %) as important influences. These factors remained consistent with findings from a prior vaccine season. Vaccine access, education, and peer-reviewed information remain drivers of HCP vaccine uptake. Strategies should address occupational disparities and emphasize transmission risks. •Older healthcare personnel had higher odds of booster receipt.•Healthcare personnel with graduate degrees had higher odds of booster receipt.•Infection risk, family safety, vaccine access, and literature influenced decisions.•Factors remained consistent with findings from a prior vaccine season.•Availability and peer-reviewed info are key to healthcare personnel vaccine uptake.
