It's not over. Developing the vaccine was the easy part--getting it in 6 billion+ arms is the hard part that's just barely starting. That's a Manhattan project level of work IMHO.
That's kind of like the Manhattan Project itself, where the scientists at Los Alamos were only the tip of an iceberg, the rest of it being an enormous engineering and logistics exercise to produce the plutonium and enriched uranium needed.
Yeah, for some reason last year, I was under the impression that once the vaccine had been invented and approved, that would be basically the end of it. But now the prediction is that Australia won't be done until the end of the year and all experts are calling that date optimistic marketing bullshit.
Turns out giving billions of people multiple doses is actually a hard problem.
The very few EU facilities have to supply the entire rest of the world (sans RU, CN). And now the US is talking about doing a third dose per patient before exporting any doses at all.
