There is an article in The Times on the problems producing a vaccine:

"...
From Australia to America, none of these advances — impressive though they are — is cause for much hope. The hope lies in the fact that all of them are happening together.
Making a new vaccine is not a race, it is a lottery. Each of these teams has brought a ticket and whether they win depends less on speed or even skill than on getting a lot of lucky numbers in a row. Does the drug behave as they predicted? Is it effective enough to make a difference? Is it safe? Can it be made at scale?
We will only know the answers to these questions and many more when each drug has passed three phases of human trials, together taking a minimum of 12 months. We do know that this is the period when the vast majority of drugs, historically, have failed.
Cepi was set up because the process of getting to this stage — to the stage of seeing if your numbers have won- was just taking far too long.
Now, sooner than most had wanted to hope, it is facing its first major test. And precisely because so many vaccines are in play, the world’s virologists are confident that at least one will win the drug testing lottery and enter production. “Our aspiration is to have millions of doses available in 12-18 months,” says Dr Saville.
