Everyone in my family has gotten vaccinated, including my six and nine-year old daughters.
How about you?
This is at the CDC website today:
Significant increases in flu activity in the U.S. in the last three weeks indicate that an early flu season is underway. CDC urges you to get a flu vaccine now if you have not done so already this season.
Prometheus Unbound 
Perhaps you have a different vaccine, but here it’s been known to cause narcolepsy. It’s hard to know what to do but I don’t trust the authorities. I have a robust immune defence so I rather catch it and sweat it out than risk being really sleepy for the rest of my life. Small risk admittedly, but large consequence. But maybe for children it would still be advisable to take the vaccine given the increased risk. Who can tell?
It’s not a hard call. It’s reasonable for every person to get an annual flu shot. In about five years, they’ll have a flu shot that will last for the rest of one’s life (with perhaps one booster).
