My husband and I did not get the flu shot this year even though I was admonished to by my OB. I just ran out of time. Then my 6 year old got the flu. I slept with him the first night, before I knew he had the flu, to keep tabs on his fever. Then I figured he was doomed and slept with him the second night after he had confirmed flu. His pediatrician prescribed Tamiflu, but it was $210 with insurance. We did not think the cost was equal to the benefit.
In the end, my husband and I avoided the flu. We washed our hands obsessively and lysoled the heck out of the house. I teach at a university a couple of times per week though. We will see if I last the rest of the season.
