If a person lives in an environment where they are exposed to lots of other people, getting these shots is probably a good idea. When I was working, and had to enter crowded elevators with "hackers", and handle door knobs, etc., that someone had probably slobbered on, I could usually count on a bout of flu, and a couple of head colds every Winter. Now, that we have moved to the country, I haven't had the flu once, and only a couple of minor sniffles in the past 14 years. The wife got a flu shot about 2 years ago, and all it did was Give her the flu...and she had to stay close to the stool for 3 or 4 days. I will continue to "pass".
