I somehow lucked out and was able to find an appointment on my first try. My friend, in contrast, couldn't find anything and ended up driving to Yakima from Seattle to get a shot from FEMA. I don't understand this. Why would a large city, which is much higher risk but with far more hospitals and ultra-cold storage be far less capable of providing drive-up vaccine service than Yakima? Did we allocate far too many vaccines p/person to rural communities? The article suggests rural communities are less likely to want the vaccine but it doesn't make it clear if distribution was based on demand at all.
