2009 H1N1 Influenza Virus and Seasonal Influenza Virus
In the wake of the 2009 H1N1 influenza virus (formerly known as Swine Flu) outbreak, the College has compiled pertinent clinician guidance and resources, including information for pregnant and postpartum women, and updates this regularly.
CDC's message is that the highest priorities are to immunize and treat pregnant and postpartum women with influenza-like illness with oseltamivir as soon as possible; treatment should not be withheld pending results of testing for influenza, if testing is done. CDC states that "case reports of adverse pregnancy outcomes and maternal deaths have been associated with severe illness."

Important Information about the Safety of the H1N1 Flu and Seasonal Flu Vaccines! Some pregnant women are concerned about the safety of 2009 H1N1 flu and seasonal flu vaccines. Both flu vaccines are safe. Vaccination is one of the most important things that you can do for yourself and your baby. Vaccination is safe for you and your baby. Both shots protect your baby from getting the flu. Your baby cannot get the flu shot until 6 months of age. The seasonal flu vaccine has been given safely to millions of pregnant women over the past 45 years. Flu shots have not been shown to cause harm to pregnant women or their babies. The 2009 H1N1 flu vaccine is made the same way as the seasonal flu vaccine. The type of mercury used in some vaccines has not been shown to be harmful to a pregnant woman or her unborn baby. Mercury has not been found to cause autism. However, if you are still concerned, there is an H1N1 shot without mercury [may or may not be available in your area]. The risk for a pregnant woman and her unborn baby of getting sick with the flu is far greater than being vaccinated. If you did not get the flu vaccines during pregnancy, you should still get them even if you are breastfeeding. This will help prevent you and your baby from getting the flu.
The College and the CDC recommend that pregnant women receive the 2009 H1N1 and seasonal influenza vaccines. Pregnant women should receive the "flu shot" for both H1N1 and seasonal flu and should NOT receive the nasal spray. Both flu shots can be given DURING ANY TRIMESTER in pregnancy. updated January 14, 2010. Seasonal Influenza guidance from the College can be found in the following Committee Opinion: Influenza vaccination during pregnancy. ACOG Committee Opinion No. 305. American College of Obstetricians and Gynecologists. Obstet Gynecol 2004;104:1125-6. Available from the Resource Center (resources@acog.org) or the members' side of the College Website. Pregnant women who have been vaccinated for H1N1 and/or seasonal influenza are being asked to participate in a study on vaccine safety. Ob-gyns that are providing influenza vaccines to pregnant women who would like to contribute to the study can send an e-mail to flustudy@jhsph.edu with the subject “ACOG H1N1” or call Howard Choi or Mari Griffioen at 410-955-6964 for more information. Ob-Gyns and their health care staff should be vaccinated for both 2009 H1N1 influenza and seasonal influenza to protect themselves as well as their pregnant patients. Health care providers were designated by ACIP as a target group to receive the H1N1 vaccine. See also the following ACOG Committee Opinion: Primary and preventive care: periodic assessments.
