Those of you who have read some histories of the Flu of 1918 (as opposed to reading just headlines), or some of the less overwrought news (e.g. at the CDC) may recall that there was a 1918 Springtime outbreak of flu that preceded the more virulent Autumn one. (I liked John Barry’s book, the Great Influenza, but there are others, many others.) You may also recall that those who caught the early, less virulent form either didn’t get the deadly one or had a better outcome if they did (they lived) than those who had not been exposed previously. They were, in purely layperson’s terms, “vaccinated.”
As my father used to say about Calculus 101. If you survived it, you had been vaccinated and were immune; you didn’t have to get it (take it) again. You might go on to get Calculus 201, but you had a better chance of survival than if you hadn’t been exposed previously to Calculus 101.
This is true in many ways. Those who are exposed the most over their lifetimes to the perils of germs and viruses and different types of food, and bigger perils (including temptation), are often tougher for it and are more likely to fight off future attacks and survive.
Nothing to fear but fear itself? Maybe, but do wash your hands, keep them in your pockets, and sneeze and cough the way you were taught as a child. And if you don’t have health insurance, call your Oregon and U.S. Senators and Representatives here or here.
