I did have Bronchitis several years ago, which I got from an Acquaintance at Walmart, and I wasn't even close to her. I was probably 10-15 feet away from her. She told me that she had it.
The pneumonia shot us very effective and a good thing for seniors ( yeah Im one) to get. Pneumonia ( even when you are young) can be really nasty
Im not a fan of flu shots. Have only ever taken one. Didnt do much because they guessed wrong. Got sick. Ive had Hong Kong flu (68-69 season). And the original H1N1 go around. Influenza aint fun. Neither is pneumonia. Worst I ever felt was with measles
