If I haven't run out of early vaccines, I'll add a fourth, I-D, people who live in high risk zip codes. Santa Clara County breaks cases down by zip code, so I'll assume others do, too.

I think this is a very fair way to distribute the vaccine once the first three groups are served. It also has the advantage of attacking the disease where it is a problem, not where it is not a problem. Reducing spread in "hot spots" is good for everybody, not just the people who live there. It may turn out that changing the requirement to "live or work in a high risk zip code" is better from the public health point of view, but IMHO either criteria is a good one.
