This year’s swine (H1N1) flu outbreak and subsequent vaccine program has spurred a great deal of interest, confusion, and misinformation about flu vaccines. We recently discussed the five most common misconceptions about flu vaccines, but rumors and questions about this year’s swine flu vaccine persist. We’re going to continue to answer your questions, so keep them coming in the comments section.

Q: Should I get the flu shot or the nasal spray version of the vaccine?

A: Both are safe and effective according to the Food and Drug Administration (FDA), but the shot is probably best for most people. The nasal spray is not approved for those under 2 years old, those age 50 and over, or anybody with an underlying condition. This version contains a weakened live virus, rather than a dead virus, can cause some minor flu-like symptoms as a side effect, unlike the flu-shot.
