It's that time of year again. No, not autumn, when all the leaves turn to beautiful shades of red and yellow. (That doesn't happen in southern California, where I live, anyway.) No, not postseason baseball showdowns. (My Angels are out of it this year.) And no, not the new fall television line-up of cop shows and medical dramas. (My wife is a fan, but I'm still waiting for a new "Star Trek" series to come out.)

I'm talking flu shots. Every October the new flu shots come out, people panic that this may be the worst flu season ever, and everyone scrambles to get injected. I won't bore you with all the pros and cons of whether or not you should get a flu shot. I want to focus on making sure those of you who get one are doing so in the safest manner possible.

Make sure you get the flu shot without any other simultaneous vaccines. Why? Because flu shots have not been studied for safety when simultaneously given with any other vaccines. How do I know this? It's written in every single flu shot product insert. Go to section 7.1 for most brands of the flu vaccine and you will find a version of the following statement: "There are no data to assess the concomitant administration of [the flu shot] with other vaccines." In plain English: Scientists haven't studied what the side effects might be when the flu shot is given at the same time as any other vaccines. Some brands don't have a section 7 and don't make any mention of safety research with other vaccines...
