Some years they get the strain wrong.
so, like others have said, sometimes they get the strain wrong, but my understanding is that the shot lasts for more than one year for that strain, so I would hazard to guess that if you get it every year each year you're immune to more strains. Also, as far as I know they've injecting dead virus and not just weakened, but your immune system will still respond as it's building antibodies, but there isn't any chance of the virus spreading in your body or to others.
I've never fully understood the point of the flu shot.
It's an estimated guess that they got the right strain. It's a pretty good guess, but still pretty much a guess.
So you get a jab, and you hope it works. Or maybe it won't.
Kinda like reality... maybe you'll get the flu anyway, or maybe not.
If you aren't exposed to a lot of children or adults, and spend a lot of time away from people, though, it doesn't make much sense to get a flu shot, does it?
You're at greater risk that you'll be injected with something against which your body reacts poorly, versus risking catching the flu from some asshat in a grocery store who didn't cover their mouth.
But then, we have fewer considerate people these days, and populations only grow, so, I dunno, maybe that risk is worse than I originally thought.
I just fucking hate needles, though.
It seems to me that when a particularly virulent strain comes along, they NEVER get it right.

Everyone I know who gets a flu shot feels sick for days after. Maybe
not quite the flu, but flu like symptoms.
Not me. When I get it, I have no response. None.
