Daddkev, I'm sorry to hear that you and your family got the flu. It is miserable, and I hope you folks recover soon.
For folks debating on flu shots, they are good to get in my opinion. They'll reduce the odds of getting it but not eliminate the chances altogether. Given that they are very easy to get these days and free or very cheap (and given how miserable it is to get the flu), I think it's worthwhile for the whole family to get them to reduce the odds of getting the flu.
