The question you asked is when will it have an impact and the answer is with the first dose given to the first patient. And more of an impact when the second person gets an initial dose. With each additional person who gets some protection we all get some protection. It is the accumulation of all these small incremental benefits that finally helps a community or a nation reach herd immunity. But it all starts with one person's inoculation which helps that person and everyone else.
