10 Myths About The Common Cold

The sun may still be shining most of the day, the temperatures may still be above 70 degrees, and the pro football season hasn't kicked off yet. But around the country, some doctors are already receiving their shipments of flu vaccine.

With the start of flu season less than a month away, we took a look at 10 common bits of advice about colds and flu. Some of these common wisdom gems are, indeed, things you can and should do (it turns out that it's not too early for a flu shot -- and you might want to pick up some chicken soup). Others, however, are things you might want to pass on (the zinc and echinacea -- at least for now).

While you may have heard some of these rumors since childhood, they aren't all things you really need to worry about. But some are useful to keep in mind.

Fact or Myth? If you get the flu vaccine too early in the year, your protection will wear off before flu season ends.

Answer: Myth

Some physicians already have their first flu vaccine shipments in, so people who believe this myth may be holding out when they don't need to.

The flu vaccine -- once understocked and reserved for the people most at risk -- is now readily available and recommended for everyone, so some doctors receive their shipments as early as August.
