Yes, for me. I don't yet about hubby and kids. Probably. I had a flu vaccine in December, and I'm actually at home with the flu right now. I'm wondering if it's Swine...it's pretty nasty!! Yesterday I was so sick I couldn't even get out of bed to walk!! Today I can hardly get a good breath and I'm exhuasted with a bad headache, and achy body. So, if I can avoid having to go thru this again, I'll do just about anything!!
