They use existing infrastructure. We don't have government hospitals and doctors in every city, it's easier to reimburse doctors and clinics to give out vaccines. We have a post office system hundreds of years old, which has worked fine for 95+% of that time. The idea that we need to rely on Amazon to send all postal mail, which they aren't actually capable of doing, is so strange to me
