British Vaccines may or may not work and not due this year

Professor Robin Shattock, who heads a team developing a coronavirus vaccine at Imperial College London ... said that until a vaccine is found, "cycles of virus" will continue and more local lockdowns will be needed.

The other vaccine also in human trials is at University of Oxford. 

The professor said ... "still not a certainty that either of those two will work."... and if the human trials worked ... "we could have that vaccine rolled out across the UK in the first half of next year."...
