I don't have a good scientific explanation, but I've read in many places, and been told by several doctors, that when you are pregnant your immune system is somewhat repressed, making you more likely to catch whatever bug comes your way. So far I've been fine, but then cold season hasn't started yet. I counted this morning, after holidays and leave, I only have 25 days worth of work left. I feel my chances of avoiding germs will be much improved when I'm done with work.

I'm going to read the link posted above on the flu. I'm still waiting to hear from my best friend who is a DO (doctor of osteopathy) what she thinks about me getting a shot.
