I get a flu shot every year. It ain't a guarantee you won't get it but it helps make it a weaker case if you do. My mother was an RN and always made us get every vaccination available. It's work'd so far except for Measles. I got them as a kid even though I had the vaccine. The doctor said it couldn't be Measles since I had the vac, but Ma was right, as usual, but it wasn't a bad case. Of course, I was also taken to the kid's house who had Chicken Pox to get that out of the way. I've gotten the Shingles vaccine too because I saw Ma go through it and don't care to have it.
