Participants
We interviewed twenty participants from nine care homes, representing different roles, level of experience, and managerial responsibility within the care home. Participants included: heads of care (n = 3); care home managers (n = 6); care assistants (n = 3) nurse (n = 1); administrative staff (n = 2) and domestic staff (n = 5 e.g., housekeeping and kitchen staff).
The size of the nine care homes varied from 24 beds and 80 beds. The care homes mainly provided residential care, some had nursing units and most had specialist provision for dementia care.
Interviewees reported different experiences of the pandemic, but most had been severely affected by COVID-19 at least once during the pandemic. Some were mainly affected in wave 1 (March-May 2020), while others were badly affected in wave 2 (October 2020-January 2021). One care home lost a third of their residents during the pandemic and other care homes reported up to 75% of residents and 50% of staff became infected with COVID-19 in wave 2.
Interviews lasted on average 46 minutes (range: 31–66 minutes). All 20 interviewees reported having been offered the vaccination and having accepted it. Interviewees did not report any serious reservations about vaccination and there was broad support for its use in care homes. However, some initial hesitation was mentioned by some participants because of how quickly these vaccines were developed and their quick authorisation approval.
From the thematic analysis, five distinct but related over-arching themes regarding factors influencing vaccination uptake were generated. These themes and corresponding sub-themes were subsequently mapped onto the COM-B domains. The full set of themes, their mapping to COM-B, classification as a barrier/enabler/mixed influence, and supporting quotes are provided in Table 1. Each theme is discussed and summarised in turn below:

Theme 1: Information-seeking strategies about vaccination
Overall, this theme was an enabler to vaccination uptake. We asked participants what kind of information sources they have used to make their decision on vaccination. The majority of participants said that they either conducted their own research or based their decision to get vaccinated on information shown in the media (e.g., radio, TV) provided by the government and local hospital communications, or through discussions with colleagues and close friends/family. A few participants mentioned social media as an informational source, but there was awareness that this was a potential source of misleading information, which had contributed to many colleagues’ decisions to refuse vaccination. Most participants felt very well informed about vaccination for COVID-19. Some discussed whether to be vaccinated with friends and/or family members and other care home colleagues, particularly when vaccination roll-out started.
Most participants expressed positive attitudes towards vaccination and some mentioned that they were also having the seasonal flu vaccine to protect the residents. In this context, previous flu vaccination acted as a familiarisation factor (and hence an enabler) for exposure to vaccine information. As a result, these individuals reported that they did not require a lot of additional information for the COVID-19 vaccine.
It was acknowledged that the care home employers supplied a lot of information to their employees, which had facilitated their decision-making. Many participants mentioned that they valued the information and support that they received through the care home employer. Some participants mentioned that a confidential helpline was also set up by their provider through which care home staff could get information on vaccinations if requested.
Overall, participants felt very well-informed and none of them expressed concern about not having had sufficient information available.
Theme 2: ease of access to vaccination
Having to travel to another location to get vaccinated was identified as a barrier to vaccine uptake, as this made some individuals reluctant to receive the vaccine initially. However, ease of access and convenience of vaccination when vaccination was later offered in the care home was reported as an enabler.
Some staff members were also taken by surprise with how quickly they were offered the vaccine and reported that they needed more time to carefully consider and process all the available information before taking the decision to be vaccinated.
Theme 3: Social interactions and support from managers, colleagues and care home organisations
Social influences, in terms of participants’ social network and interactions, were identified as a key enabler to vaccine uptake. When participants were asked about the attitudes of their friends and family members towards vaccination, they all indicated that they had very similar attitudes to their own.
Some of the main reported reasons for why people who were initially reluctant to accept the vaccine changed their mind included seeing that others who had been vaccinated remained well over time, (i.e., they had not experienced any serious side effect) and positive and reassuring conversations with colleagues and with their employers.
All participants mentioned that their care home employers encouraged their staff to accept the vaccination, but none reported that this resulted in them feeling pressured by their employers to do so. Furthermore, all participants explicitly emphasised the importance of giving people the opportunity to make up their own minds (enabler).
Participants were asked about their interactions and discussions with colleagues who decided not to be vaccinated. They all reported encouraging colleagues to be vaccinated and to change their minds, but also emphasised that they respected their colleagues’ views and their right to choose whether to be vaccinated or not. All participants valued the fact that staff had autonomy to make their own decision. They suggested that their vaccine hesitant colleagues should receive more information and that it was important to listen to and address their concerns. They felt that pointing out that vaccination was a ‘way back to normality’ was likely to have a positive influence on staff’s decision to be vaccinated (enabler).
Theme 4: Beliefs about benefits of vaccination
Participants clearly stated their perceived benefits of vaccination, which motivated them to get the vaccine (Enabler). Reasons provided for accepting the vaccination included staff own protection, protection of residents and close contacts/family members, leading by example and doing what is for the “greater” good, allowing more freedom in the future and believing that it was the ‘only way back to normality.’ Some participants mentioned that being vaccinated would allow them to travel abroad, which was particularly important to those staff members who were originally from a different country.
All participants stated they were not doing anything different following vaccination. The same protective measures were still in place post vaccination (e.g., PPE and social distancing) and continued to be followed. They also stated that they would also adhere to the same personal protective measures in their lives outside of the work environment.
In contrast, when asked about their unvaccinated colleagues’ attitudes and beliefs, participants believed that concerns about potential side-effects was the main reason for their colleagues’ hesitancy (i.e., barrier to vaccine uptake). In particular, those with pre-existing health conditions were especially concerned and apprehensive that vaccines might not have been tested appropriately and that the evidence base was still very limited.
Some participants perceived that vaccine hesitancy could be more prevalent among different ethnic and religious communities who have limited trust in public health authorities.
Theme 5: Emotional response to vaccination
Emotions represented a mixed influence on vaccine uptake. Many participants mentioned that they felt happy about getting the vaccination. One participant even reported having cried out of relief. For some others, it was less emotional, and they just felt they had to do what they had to do. One participant mentioned feeling “better about themselves” after the vaccination. Some participants reported not having any particular emotional reaction to the vaccination.

We propose four intervention types (i.e., education, enablement, persuasion and modelling) and nine BCTs (e.g. action planning, social support, credible source) to target individual knowledge, motivation and emotional influences on vaccine uptake. Some interventions focus on increasing the individual knowledge about vaccination and the motivation of CH staff to get vaccinated. Other interventions focus on reducing any emotional concerns from being vaccinated. Therefore, an educational-based intervention aims to increase knowledge and to address the perceived lack of credible, reliable sources of evidence about vaccination. This educational intervention can be tailored to the care home setting, for example, provide details of where to locate scientifically robust evidence about vaccination that is in a comprehensible and reader-friendly format.
Other interventions focus on increasing ease of access to vaccination centres (enablement) and improving communication and promotion of vaccination by appointing a person in a leadership role to ‘champion’ being vaccinated (persuasion and modelling). This role is to encourage staff to be vaccinated and to reduce any concerns about side-effects (e.g., not being able to work), vaccine safety and risks from having pre-existing health conditions.
