The Oxford/Astra zeneca developers did their own announcement today. They class it as 90% effective based on the testing trials, but it's two doses now (or one and half, for some reason) rather than being a planned single dose vaccine. So the Government probably hasn't bought enough of that one after all.
I would urge caution and not get too over-excited about the Oxford vaccine yet:

I am sure Boris Johnson creamed his pants when he heard those figures from something developed at his alma mater, but there is always a risk of some people potentially not doing proper science to get there first.
