not yet, but as 50+ will be getting one at some point.
mum-tat (who's 80+) has had her invite to book today. she's a bit confused about whether it's better to go to the same place as last time (she has had pfizer for all three so far) on the expectation she'll get the same again, or what.
place she's been summoned to before is a bit awkward to get to - she lives almost in one corner of lewisham borough, this place is the opposite corner, so it's 2 buses on (by london standards) not that frequent 'back road' routes to get there.
anyone know what the best thing to do is?
I cant give a omprehensive answer but I suppose I can come out with this sort of impression:
During the first 2 doses being rolled out, in theory there were places that would have struggled more with logistics of Pfizer storage/handing compared to Oxford AstraZeneca, and so sometimes location influenced which vaccine someone got. But timing of supply of the different vaccines within the system was a big factor too, and the timing of when the government went off Oxford Astrazenca vaccine, and initially the age of people during that transition away from the Oxford one.
And since then things evolved. Oxford AstraZeneca is not part of the UK picture these days, and lots of Moderna, which is the same sort of tech as Pfizer, was around from a certain stage onwards of later vaccination campaigns. My Mum ended up having three Pfizer, my Dad and brother ended up with two Oxford and then a Pfizer, I ended up with two Pfizer and then a Moderna.
On paper looking at various numbers in the UK vaccine surveillance reports, I'd say that those who had two Oxford doses to start with and then got a Pfizer or Moderna for a 3rd dose ended up with some better protection numbers on paper than they'd had after only receiving Oxford. And a Moderna third dose after two Pfizer doses also resulted in numbers that looked good to me. Three Pfizer wasnt bad either, and I cant say that I was left with a really strong sense that it would have been significantly better if my mother had had a Moderna third dose rather than a Pfizer one. But at a minimum I was happy to have received that combination myself, and would have been quite pleased if my mother had ended up with that combo too.
This time around we've got a situation where updated Moderna vaccine which now includes an Omicron component got approved, and then even more recently a Pfizer version of that new combo that includes Omicron also got approved. Some people are saying that there is enough supply of the newer vaccines that everyone should end up with one of those, although the plan does still allow for the original vaccine types to be given to people if thats what logistics in a particular time and place dictate. We wont get the fullest possible sense of how much difference these updated vaccines make compared to the old ones until that data is collected via massive amounts of real world data, including how well they end up working in practise when faced with whatever strain of Covid tries to take off in this country in the next wave(s) to come. And I dont know whether the available supply will be dominated by Moderna or Pfizer, or how the proportions may evolve over time.
Since the various unknowns mentioned there cannot be predicted, I would resort to other factors when considering what is best for your mother. She probably should not anticipate being able to control, or place high emphasis on, receiving the same vaccine as before, and should let other factors of practicality and confidence guide her I guess. Including going for the option that gives her the least personal unease even if that unease is not necessarily strongly routed in really significant factors. And as you can probably tell by now, some factors are not really within her control, they will come down to stuff that is indistinguishable from 'luck' and that cannot be accurately predicted or controlled by making a decision about location.
