Background/Objectives: Vaccinating care home staff is essential to protect vulnerable residents by reducing infection risks and creating a safer care environment. However, vaccine hesitancy amongst staff remains a challenge, particularly since the COVID-19 pandemic raised concerns about side effects and vaccination mandates. This study examines how the pandemic influenced flu vaccine hesitancy amongst UK care home staff. Methods: Data were collected from the FluCare trials conducted over the 2021–22 and 2022–23 winter seasons to explore the impact of concurrent mandatory and non-mandatory COVID-19 vaccination policies on flu vaccine uptake. A total of 52 interviews (21 from the feasibility study and 31 from the randomised control trial) were conducted with care home managers and staff. Thematic analysis identified key themes shaping staff attitudes toward flu vaccination. Results: Four central themes emerged regarding the impact of the pandemic on staff attitudes and the contextual influences shaping vaccine hesitance: (i) tension between autonomy and morals in vaccination decisions; (ii) the COVID 'craze' and the displacement of the flu vaccine; (iii) the role of the COVID 'craze' in staff vaccine fatigue; and (iv) conspiracies, (mis)information, and the significance of trust. Psychosocial theories on decision making and health behaviour were used to further interpret the findings. Conclusions: Our findings suggest that post-COVID-19 interventions in care home setting should address the issues of autonomy, vaccine fatigue, and trust to enhance vaccine uptake. Understanding these factors could support more effective strategies to address hesitancy amongst care home staff in future vaccination campaigns. [ABSTRACT FROM AUTHOR]

Barriers and enablers to vaccination of care home (CH) staff should be identified in order to develop interventions to address them that increase uptake and protect residents. We aimed to synthesis the evidence describing the barriers and enablers that affect the influenza vaccination uptake of care home (CH) staff. We searched PubMed, MEDLINE, EMBASE, CINAHL, PsycINFO, AMED, IBSS, SCOPUS to identify quantitative, qualitative or mixed-method studies. Data related to health or social care workers in CHs reported barriers or enablers were extracted and mapped to the Theoretical Domains Framework (TDF); the data within each domain were grouped and categorized into key factors affecting influenza vaccine uptake among CH staff. We screened 4025 studies; 42 studies met our inclusion criteria. Thirty-four (81 %) were surveys. Five theoretical domains were frequently reported as mediators of influenza vaccine uptake: Beliefs about consequences (32 studies), Environmental context and resources (30 studies), Emotions (26 studies), Social influences (25 studies), Knowledge (22 studies). The low acceptance rate of the influenza vaccine among CH staff can be attributed to multiple factors, including insufficient understanding of the vaccine, its efficacy, or misconceptions about the vaccine (knowledge), perceiving the vaccine as ineffective and unsafe (beliefs about consequences), fear of influenza vaccine and its side effects (emotions), and experiencing limited accessibility to the vaccine (environmental context and resources). Interventions aimed at increasing influenza vaccine uptake among CH staff should focus on addressing the barriers identified in this review. These interventions should include components such as enhancing knowledge by providing accurate information about vaccine benefits and safety, addressing negative beliefs by challenging misconceptions, managing concerns and fears through open communication, and improving accessibility to the vaccine through convenient on-site options. This review provides a foundation for the development of tailored Interventions to improve influenza vaccine uptake among CH staff. [ABSTRACT FROM AUTHOR]
