When you say they were sick, do you mean a cold or really the flu? The flu shots won't prevent all flus, but if you get it, the shot should help lessen the severity and duration. Make no mistake, the flu can cause death in compromised individuals, maybe your husband and father were lucky last year, maybe it could have been a lot worse. I get the shot every year, especially if I've been sick and think my health may be compromised in any way.
Each season the flu mutates a little and the shot is never exactly the same flu that you may get, but the science says they're similar enough to help your body build antibodies and fight it anyway. The more similar, the better your body will fight it. You may still get a flu, but this way your body has a starting point to help fight it.
You may want to have your husbands doctor explain how the flu shot works, he could be at risk if doesn't get one.
