I got the H1N1 shot last month and had no
side effects. It cheered me up so much to get it, I had been basically wincing every time anyone sneezed in the grocery store. I am someone who also got a seasonal flu vaccine at a time when I was pregnant, and had no side effects or issues from it, either. Unlike other flus, H1N1 (the illness, not the shot) has been very dangerous for pregnant women, so please don't take the threat lightly. The shot stings a little bit, is all I found.
