They say pretty much what you posted, which is pretty much what I posted earlier. As I posted earlier, they have also pointed out that there is some protection after the first dose, and there is the basis for an argument to support rolling out the vaccine by getting as many people as possible to receive the initial first dose, so to minimise the impact of infection in order to reduce the strain on the health service for a period, before focusing on the second injection.
As far as I can tell, the focus is still on issuing the two injections within the timescales.
My sister and brother in law in Hull have just had their first Pfizer vaccine injection and been told not to expect a second dose for up to 12 weeks. They are both in their late 70's.
just doesn't do this justice...
