UK coronavirus live: Boris Johnson says £12bn test and trace helping a bit in Covid fight but must improve – The Guardian

Things are progressing well, there are vaccines that produce an immune response, they’re in phase three clinical trials, we should be seeing some data read-outs over the course of this year, but I remain of the view that the possibility of wider-spread use of vaccines isn’t going to be until spring or so next year by the time we get enough doses and enough understanding of the outputs to use them.

Now we may get a few doses this side of Christmas, maybe something could happen, but I think we should more realistically be looking at spring, and of course there are no guarantees until the studies have read out.

So we need to be cautious and carry on, but there is a good progress in terms of the vaccines.
