It looks like England are upping their second doses too, albeit not by as much (as a proportion of all vaccines) as the increases in Wales and Scotland. Be interesting to know if the trend continues ahead of the 12 week threshold or whether it levels off. I suppose it’d also be interesting to know if they’re Pfizer, AZ or a combination of both.

The variation is most likely due to the need to ensure second doses happen not more than 12 weeks after the first. If need be, that will involve doing them sooner rather than later. There’s no signal in your data that anybody has taken a clinical decision to deliberately move to a different dosage schedule.
Despite the roaring success of our vaccination programme so far, we do still have finite capacity for conducting vaccinations and finite quantities of the vaccine itself. To complicate things further, supplies of the Pfizer vaccine, which is the one given to all our earliest and most vulnerable recipients, are constrained at the moment while they concentrate on bringing new production capacity on stream. This constraint has been known about for many weeks and was planned for.
It is imperative that these people get the correct vaccine and that they don’t get it too late. It seems to me to be perfectly sensible to go slightly early if that’s what available resources dictate. How good it is, though, to be in a position to take such decisions from a position of strength.
