I've said this will be an incredibly difficult challenge all along. But we've had 6 months to plan it. If serious "feet on the ground" planning and work has been accomplished in the last 6 months, I've missed it. This needed to be a top-down mandate with funding to make it happen. For instance:
Priorities: First responders, people in assisted living, healthcare. After that, by age buckets.
Volumes: Each congressional district (set by population, right) must set up facilities and staffing to inoculate 50,000 individuals/wk for 6 months given 30 day's notification. It is assumed that each inoculation will require an hour's nearby parking for a vehicle, plus 5 minutes of induction time, 5 minutes of inoculation time, and 15 minutes post-inoculation observation for each recipient. Plan for 2% of recipients to have a reaction to the vaccine and to need an epi-pen or other treatment in a nearby facility. Have first responders and transpiration on-site to provide this level of care. This is likely to require a minimum of 20 locations per district, fully staffed 24/7 for the duration of the effort.
Communication: At the arrival of vaccines, communicate to the community at large the approximate vaccination "windows" for various groups. Provide weekly updates.
Responsibilities for each district: Set up 20 or more vaccination locations, complete with parking and appropriate facilities. Follow prescribed communication plan. Etc.
It is a big job and I don't think many locale's have been grinding away to comprehensively solve the "final mile" problem.
