Many of the "loopholes" are part of waste prevention strategies - if they defrost 100 doses and only use 75 on "eligible appointments" that actually show up then the next best thing from a public health perspective is to put those extra 25 doses in a human arm. Any arm. Otherwise, they go in the trash and nobody wins on that. In Louisiana there is actually a box to check on the eligibility questionnaire that is "Waste Prevention" and that puts you in the line for the invariable extras. In California, it's a first come-first served approach as a "waitlist" lineup outside vaccine facilities. At the end of the day, they come out and call in as many extra people as there are extra doses. I heard in NY there is an app you can sign up for that will give you "last minute" same-day appointments if you can get there. Likely to cover no-shows.
