Got mine today, always get one. Blackhorse's points were well presented, especially #4. My wife is in charge of making sure that all 4,000+ employees at a regional Hospital get theirs, so I could not avoid it even if I wanted to (which I don't). She has been in charge of the annual flu shot program for many years, it takes up about one-quarter of her annual workload, so she's quite an expert on this topic.
While there are some medical conditions that would preclude getting the shot, I think many of the excuses are pretty bogus. Perhaps it's just me, but I would think that if you worked at a major hospital, many patients with severely reduced immune systems or abilities to handle another infection, it should be expected. There are some that do not believe the hundreds of refereed and vetted medical studies over decades, but rather follow what their cousin told them, or what an actress said about how it causes just about every malady we see on earth today.
By the by, it's a quadrivalent again this year (it used to be a trivalent, but for the past couple years it has been designed to protect against the four strains that were the major ones in the southern hemisphere over their past winter. Last year, one of the strains being grown for the shot mutated in the process, so it wasn't as protective for that strain as originally predicted. Still, even if a strain the shot wasn't created to cover pops up in the northern hemisphere, it still offers some protection and helps speed the recovery.
Ozark Wizard, it seems to be a very personal thing as to whether one gets a sore arm and mild flu-like symptoms from getting the shot or not. She always feels it for a few days and her arm aches for a week. I never get any reaction.
