Even if the Oxford vaccine failed, they have the infrastructure and Big Pharma connections in place. When they get a hold of one that does work (from some university or non Big Pharma rival) they can run with it. There are so many vaccines in the works, it's highly likely they can license one that does work.
I've done some antibody production work for research purposes, decades ago. It isn't all that difficult. We succeeded in making horse and goat anti-dog lymphocyte antibodies and failed when we tried to make rabbit anti-morphine antibody.
