There is a lot of misinformation and hype about vaccines out there on the internet and of course getting a vaccine is a personal decision. I did want to mention that one of the reasons health professionals really emphasize the flu vaccine for pregnant women is that when you are pregnant your body enters a state of mild immune suppression (to keep it from rejecting the baby?) Thus, it is much easier to become sick when you are pregnant and if you do get sick you have a much harder time fighting the illness because the usual immune support just isn't available to your body. If you have other little ones running around the house you have many more sources of germs to make you sick. If you are unsure about getting yourself vaccinated right now, you could protect yourself a little from those sources by having all your children (and husband and anyone else you spend a lot of time with) vaccinated. Of course, hand washing and not touching your face will also prevent exposure, but while you have a lot of control over what you do, it is a lot harder to monitor children.
Personally, I get the flu shot every year (pregnant or not) because I don't like to get sick and I trust that my doctor has my best interest in mind. I do verify that I get a thimerisol free shot, but almost all shots are thimerisol free these days.
