The vaccines are known to usually lessen the symptoms even when they aren't a perfect match, so even if the herd immunity stuff doesn't float one's boat, self-interest should.

Last year was the first year I ever got a flu shot. A couple months after being vaccinated, I got a different virus that caused a near-fatal case of bronchitis. I suspect, but cannot prove, that if I had contracted the flu at the same time I got the bronchitis, I wouldn't be here to bore you with this.

Infections that affect essential organs like the heart and lungs shouldn't be taken lightly, especially as we age. Flu isn't a big deal for young folks, but it kills us elders with great frequency, even when we appear to be healthy prior to infection. That said, everyone here is an adult and gets to make his/her own decisions. Whatever anyone decides, I hope it works out for the best.
