> I imagined a lot of low income and poor people lining up for a shot they may not need, and in fact may be harmful

That's an interesting spin, which may be true of other types of injection. However for flu shots, it can save lives (the poor are particularly susceptible and potentially focal for infection clusters). In that way the financial incentive is progressive.

Does the flu shot save lives? Various outlets report the vaccine may only be roughly 50% effective [0] which seems little more than a coin toss. They're pushed very hard in these drug stores, every time you check out, signs everywhere, plus the financial incentives. I wonder what the danger would be to a poor person to getting a flu shot multiple times?
