That is interesting. Perhaps Texas is a lot different than rural Illinois where many small towns have clinics and pharmacies. The nearest town to my residence boasts a population of 850 and has not one but two clinics affiliated with major health care providers in the region.
Plus people can get flu shots at about any pharmacy as well. I’d imagine pharmacies will be investing into the equipment necessary to administer the vaccine.
And on top of those factors, people in rural communities are also conditioned to travel long distances regularly. I dated a girl from central South Dakota for 18 months. Her parents own a large ranch 20 miles from the nearest map dot of a town. Because that little tiny town serves such a large geographic area it does have the essentials like a gas station, grocery store, pharmacy etc. There are many more just like them and they all seem to survive just fine.
So I don’t think it’s going to be a nightmare logistical issue. Rural people who want the vaccine will be able to find a way to get it. I believe the real challenge is that a relatively low percentage of those people will want the vaccine in the first place. Especially one that uses a new technology that’s been rushed through production without the usual safety protocols.
