Coronavirus: Vaccine Standby Lines in Los Angeles

I've written a couple other articles about how people are jumping the vaccine line (or attempt to jump the line). I've written about how the wealthy are attempting to bribe their way to the front or just have certain healthcare benefits that will get them ahead of others. I've also written about vaccine tourism, which probably is an upper middle class and above situation. Now it appears that ordinary people have figured out a way to jump the line. The LA Times (Jan 23) reports on this:

There is, officially speaking, no such thing as a standby line for COVID-19 vaccinations in Los Angeles County.

But some clinics have soon-to-expire doses left over at the end of the day or during an early-afternoon lull, and word has quickly spread about this potential back door to vaccine access. Some who flock to the sites spend hours waiting in the hope of catching a lucky break. 

This isn't a significant loophole to get a vaccination ahead of others. The article mentions that LA county health officials believe it is between 20 to 30 people a day (not sure if that was per location, doesn't say). The journalist did determine that 40 people in the standby line were given the vaccine at one location (out of 800 that were administered). And there was a rumored 200 given out by one location, but then that is just a rumor which could have gotten exaggerated.

What about the ethics of standing in the standby line? My own personal opinion, it is far less than trying to bribe your way to the front or going on a vaccine tourism trip. As mentioned in the article, Pfizer and Moderna vaccines have a limited shelf-life. It is use it or lose it. If someone doesn't show up for their vaccination (for a variety of reasons), it is better to give those doses to other people even if those individuals are way outside the age group that currently qualify for the vaccine. Now if the Johnson & Johnson or Astrazeneca vaccines have a longer shelf-life, I'd assume that standby lines would not be allowed.

Now: are these lines potential super spreader situations?
