I haven't and have no real plans to this year.
They guessed wrong this year and didn't pick one of the strains that was on the upswing. They did get the secondary one though, I believe. So while you wouldn't be fully protected against the most common strain this year, you would be against the lesser one.
Really, though, this year it's only worth getting if you're a healthcare worker, work around the elderly a lot, work around kids, or are a kid. The rest of us, with decently working immune systems, really should only bother with it if they feel a pressing need.
