Nasty cough, three days of high temperatures, lethargy, refusing to eat -- I swore that the virus causing my two-year-old to suffer last week was the flu. But I had gotten her a flu shot back in October. What gives?

The CDC recently announced that there's a variation of the flu circulating this season that isn't covered by this year's flu vaccine. When vaccines are created, they include the top three most likely viruses to be spread. This year, a fourth bug is circulating that wasn't included in the vaccine. Is that bug the cause of our current woes? I have no idea, and since she's recovering nicely, whatever it was, I'm just glad that it's on its way out.

Does this mean that you shouldn't get a flu shot? Not at all. In fact, if you haven't gotten yours this year, it's not too late. The vaccine will still fight the three targeted viruses, and may even help you fight off this other virus and lower your risk of complications if you do contract it.
