Listen to whatever your OB/GYN tells you to do, misombra. You have different risk status than anyone else posting on this board.
As for my opinion, I think whether or not one should vaccinate depends on how healthy they are. For example, if you have asthma or COPD, you should definitely vaccinate, or stay away from people all together. the flu can kill you. If you are a health care worker, you should vaccinate so as not to pose a danger to your patients who are sick (likewise people who have regular contact with people whose immune system is already compromised). If you are a college kid (especially living in the dorms) that can't afford to miss a week of school, you should vaccinate. If you are otherwise healthy, and wouldn't mind the inconvenience of missing a few days to a week of your life, then you have other options.
