Taking a few days off

Welcome to flu and cold season!! My official welcome came a couple of days ago. With me trying to fight the illness for the last couple of days, waking up really stuffed up and with a sore throat, I woke up extremely early to three kids in my bedroom. Turns out that the Mya has been attacked by the flu bug. There we are, 4:30 in the morning dealing with a sick girl. Blah. It's now 11am and she's finally slowed down enough to sleep. Ahh, relief.

What I don't get is why you get the flu shot, but end up getting sick with the flu anways! She's the only one in our house that had the flu shot this year. So wy is she the only one in this house that got the flu? Kinda pointless don't ya think?
