There seems to be confusion as to just what "getting a vaccine" really means.
In an optimistic view, which is what Faucci seems to be taking, we could have results from a stage 3 trial that indicate that an effective and reasonably safe vaccine has been developed. That is only the first step.
The next step is to seek and get approval for the vaccine from a drug authority that is satisfied with the Stage 3 data. Typically, even in an emergency situation, this takes months, and if the process is rushed, there is likely to be strong reaction against using it. And it is unclear whether any country outside the USA will accept any approval of their FDA under the present administration, but will need to go through their own processes.
Next is the need to set up to mass produce it, and the hardware to administer it. Just what is involved will vary enormously between the candidate vaccines. Some will have a manufacturing technique similar to existing vaccines or possibly other drugs, but some require building new manufacturing techniques. One article I read pointed out that one particular drug they were familiar with had nearly 80 steps in its manufacture, all requiring very precise conditions and some crating byproducts or using inputs that could be described as extremely hazardous.
Then we have to decide on and set up how to administer it. Who gets it first? How many doses are needed and in what order? Does it need special transport and handling procedures? All of these have to be known before administration is organised.
Now there will be some overlap between these steps, but it seems to me that even if there are stage 3 results published by the end of this year (and that is by no means certain), it is likely to be close to the end of next year before we can expect Australia to be returning to something like normal, and the rest of the world (except for a few countries) is likely to be well behind that. By that time the economic impat is going to be so large that I do not see much prospect of the world looking anything close to what it did a year ago in my lifetime. (say another twenty years)
I don't think it is an exaggeration to say those times will never return. Looked back on as history, this pandemic will be regarded as a pivotal event of this century.
