今年冬天大家都要注意了

I took a day off for sick onThursday.

My current office building is a small building. A couple of coworkers have told me that the flu has been going around in the building for a quite while. My immune system is pretty good. I do not sick very often.   However, even though I got the flu shot at the beginning of October, I still got the flu two times within three months. I read an article that said the flu shot is only 10 percent effective this year, especially in the South. I think this article is probable true.
