Table 2. Contextual influences supporting quotes by participant (with participant number and engagement with vaccination).

Facilitators     a. It’s quite helpful seeing the pop-ups and the ads about flu, because I have a tendency to forget that one, and there’s always a bit of difficulty in actually getting an appointment in with a pharmacy or a GP or whatever to actually get that one. And it reminds me, “Oh, it’s that time of year, it’s out now. I ought to be doing something about it.” OPI022, sometimes vaccinated     b. The scale of it, yeah, and the fact that normally you don’t have access to what ICU consultants think or say but a lot of them have had enough so they are going on social media and saying, “Please get vaccinated, we can’t cope anymore." We see ambulances piled up, so this is no joke, is it? OPI001, always vaccinated     c. There’s also the Psoriasis UK, I think it is, website, where they had a big section about it, really helped. It made me feel more at ease and that I was okay to get it. OPI162, often not vaccinated     d. I mean I was trapped in the house…It had a complete change on everything, and it was so dominant that the thought then of not taking any help to change that would just seem bizarre. OPI225, always vaccinated     e. I suppose I didn’t ever consider the severity of disease that I might get until they started talking about, I think it was Crohn’s and Colitis UK that basically pushed forward saying that people with Crohn’s are going to be at more risk because of their immune systems and that kind of got me thinking what else should I get protected against? OPI146, often not vaccinated

Barriers     f. Probably if I saw targeted ads for the pneumococcal one, it would probably remind me to nag a GP about it again. But there just isn’t that much about it. OPI022, sometimes vaccinated     g. It’s pretty much all age-related and never really mentioned immune-suppressed or anything like that. OPI146, often not vaccinated     h. Because even though flu’s around all the time and every year you sort of don’t hear about it to the degree of what Covid has, and I guess that that made me feel that it would be more worthwhile to get it. OPI129, often not vaccinated
