Think the frustration here comes from there not being a good reason for them refusing a vaccine in favor of another, when theres still a lot of people out there who need a vaccine. So they hear of people turning up and then saying "Well I don't want this vaccine because it's not English", and they just get frustrated. Pretty much everyone wants one, although we're getting through it, pretty much everyone knows someone who needs a vaccine. Also that those being vaccined up until now were those very, very high risk (over 70, very vulnerable), and any reopening here has been tied to the vaccine numbers. So "We've all been sat in lockdown to keep there ungrateful arses alive and they're refusing to help themselves" or similar is another one I've heard a lot.
Don't know about the tablet one, not heard of a vaccine as a tablet - but lets say we do, and it's an expensive tablet, and the vaccine costs a lot less. You have someone refusing to take a vaccine without coming up with a good reason why, but says he'd be willing to take the tablet if given to him. It's public funded healthcare, so it's the taxpayer covering that. Question will come up - why should the taxpayer cover that one for him?
Ooh, Italy now is considering getting the Russian Vaccine.
