I did not get it because I never get the flu shot (I believe in building my own immunity). I may feel different if I had underlying health issues though.
My OBGYN suggested it but did not push it and showed now concerns that I chose not to get it. Also, apparently there is more concern if you are giving birth during flu season but even then I don't think she would have pushed.
So far everyone that I know who got the flu this year, HAD the shot. Those of us who did not get the shot, have not got the flu yet. Don't forget that the shot only protects you from a few strains of the flu- there are still other strains, you can still get the flu ! It just "protects" you from the few most prevalent strains.
Do what YOU feel is best for you.
