WTH is going on in America with the slow rollout of the vaccines?
In America we've slowed it down massively by separating people out into multiple groups. This is a noble idea but terrible in practice, because administrators of the vaccine don't want to get in trouble for vaccinating the "wrong" person before their turn, and are spending lots of time trying to find and schedule all of the "right" people in one group before moving on to the next group.
This is why federal bailout money has gone out to almost everyone of a certain income level, regardless of personal circumstances (employment, savings, etc.). The time and money it would have required to sort out the "worthy" from the "non-worthy" recipients would have gummed up the process, so they just bypassed that and sent everyone under a certain income level a check/direct deposit.
That is what should happen with vaccine distribution. There should only have been two very simple phases:
Phase One, in which vaccines are administered in hospitals & other health care locations to all of their willing workers once (and if you don't show up for your shot that day, too bad, so sad, you can get in line with everyone else), and in which mobile units go into nursing homes to vaccinate all willing workers & residents there (& if you're not present that day, again, you'd have to get in line with everyone else later).
Phase Two, in which everyone else has the opportunity to electronically sign up for a vaccine at major distribution centers (like city convention centers, megachurches, concert halls, etc.) that can handle a large volume of people, and if you don't show up on your vaccine day, too bad, get in line electronically again.
That might sound "unfair", but it would get shots into arms much faster than the "let's evaluate which patients deserve to be in this round, make old-fashioned appointments with them individually, then give them more chances until it seems this group is finally finished". That is what is happening now and it's a very slow process. And meanwhile Covid is raging.
There is a maxim, "the perfect should not be the enemy of the good". The ultimate goal of vaccination is herd immunity, and that will only happen once a large percentage of the population is vaccinated. And that day would come much faster if our government & health care providers stopped micromanaging the process, and just gave out the vaccine to all, first come, first served (via electronic sign-ups to avoid massive crowding).
