pregnant women everywhere. As the flu season approaches, it's important to consider your health this fall/winter because of the H1N1 (swine flu) pandemic. Now that an H1N1 vaccine has been approved by the FDA, it's very important for those who are at "high risk" to get vaccinated first (since we don't even know if we have enough vaccine for everyone else). This includes pregnant women.
The first place to start is the CDC's website: "2009 H1N1 Influenza Vaccine and Pregnant Women" that can be found here: http://www.cdc.gov/H1N1flu/vaccination/pregnant_qa.htm
That page is arranged in a question/answer format, so it will probably answer most of your questions. The important thing to remember is that swine flu (H1N1) can be fatal, even to healthy people. It's very important to discuss these issues with your healthcare provider and to make an appointment so that you can get the vaccine as soon as possible.
