My guess is that you have generated your own hypothesis (namely, more than two doses will work better than 2 will). I almost always leave medical hypothesis generation to the medical experts with the result that my job is to choose among the hypotheses and to tailor my choice to my situation. Of course I consider hypotheses by contrarians and alternative health-care providers, which number in the high dozens or hundreds of hypotheses for Covid.
(Experts have proposed a 3rd shot, but that would be a shot of a new vaccine, not one currently being given to people.)
it’s likely that the UK will offer third doses of the original Pfizer vaccine to everyone over 50 or especially at risk, some time towards the end of this year.

This does not seem to be the case in Turkey, where they are right now handing out third doses of existing vaccines to people.
This, and the Bahrain/UAE cases, seem more likely to be driven by concerns about whether/how well the Chinese vaccines work?
There are lots of clinical trials of third doses of the same vaccine (some completed and some still in progress, see e.g. https://www.bmj.com/content/373/bmj.n1659 https://cdn.pfizer.com/pfizercom/2021-07/Delta_Variant_Study_Press_Statement_Final_7.8.21.pdf ), and it’s likely that the UK will offer third doses of the original Pfizer vaccine to everyone over 50 or especially at risk, some time towards the end of this year.
Interesting, do you have a source for that?
