I think this is wildly optimistic for the US, sadly. Even Israel is likely to have supply issues.
Israel already vaccinated enough people to overcome most of the problem. It's only a question of a few weeks until the virus goes into affect. I also don't expect delays for Israel, these are very small numbers for Pfizer, it is very important to Bibbi, Pfizer is getting very good global press coverage, and Moderna is eager to step in if there really is an issue.
J&J alone is 100m. US will get at least half. By 100-150m ppl vaccinated Covid shouldn't be a problem anymore in the US.
Doesn’t that depend on how effective existing vaccines are against new mutations/variants?
The fear is very much exaggerated at this point from my understanding. The variants aren't anywhere near different enough to evade vaccines.
I'm more concerned the vaccines will fade in a year before production is ramped up enough to produce more easily, an enormous global political failure.
רבות מחשבות בלב איש, my point is just that if you look at the current course it looks like it will be over.
