Vaccination roulette

Health department nurses distribute oral        
polio vaccine ca. 1960.

I have an appointment with a chain pharmacy here in Michigan to receive my first dose of one of the COVID-19 vaccines on March 9. I don't know whether I will get the Moderna or Pfizer vaccine. There isn't any way to choose; you take whatever vaccine the vaccination site has.

Having an appointment for a vaccine, of course, is not the same as actually getting the vaccine. Lags in vaccine production, shipping delays due to weather, difficulty ensuring that there are enough people trained to administer the shots--all of this has created problems in vaccine distribution here in the United States. 

In addition, state and local health departments had to create a network of vaccine distribution sites for people in each locale, and this took time.  Like a lot of people over age 65, I remember the 1960 distribution of the oral polio vaccine and couldn't help comparing that effort to the one going on now. In our town, people were directed to their local polling stations on a given day. There, the public health nurses gave us sugar cubes with the vaccine on it. I remember teasing my younger brother that he would have to get his via an eye-dropper because, at age 4, he was still a baby.
