Depends on whether you mean the local "crud" that goes around every year, or real influenza, which can kill.
I've had the real influenza twice, once in the mid 60s in Washington, D.C. As I recall, it was the Hong Kong flu. Many people were sick with it that some offices and businesses had to close because nobody was well enough to come to work. Our office was one of them.
Then somewhere in the late 90s or early 2000s I got influenza again; I forget which type they said it was, but it was terrible and flattened me for two weeks. I seriously thought I might die of it.
Ever since that last flu, I have become quite fanatic about getting the flu shot. Before that, I never got the shot unless I was forced to by work rules. I got the high dose, over 65 shot a little over a week ago.
People confuse the local "crud", upper respiratory infections, colds, etc., with influenza. They are VERY different.
