The point is that if the analogy of a $0.04 syringe is supposed to be as expensive as a cup of coffee, it's still not expensive even if you do it often. Maybe they have too many injections. Either way we have a bunch of kids with a disease that can kill because someone thought something as expensive as a cup of coffee was too expensive.
Median household income in US is $83k so 0.04/125 * 83k is about $26, much more than cup of coffee. If you're sticking like 15 kids a day with the same needle, that's like $400 a day saved.
