Women are at increased risk for morbidity and mortality from influenza during pregnancy (1). Vaccinating pregnant women for influenza can protect both the women and their infants, especially infants aged <6 months who are not old enough to receive influenza vaccination (2--4). Since 2004, the Advisory Committee on Immunization Practices and the American College of Obstetricians and Gynecologists have recommended inactivated influenza vaccine for all women who are pregnant during influenza season, regardless of trimester (1,5). Before 2009, estimated influenza vaccination coverage among pregnant women had been consistently low (approximately 15%) (1,5). However, vaccination levels increased substantially in response to the 2009 influenza A (H1N1) pandemic to nearly 50% (6--7). To estimate influenza vaccination coverage among pregnant women for the 2010--11 season, CDC analyzed data from an Internet panel survey conducted in April 2011 among women who were pregnant any time during October 2010--January 2011. Among 1,457 survey respondents, 49% reported that they had received influenza vaccination: 12% were vaccinated before pregnancy, 32% during pregnancy, and 5% after pregnancy.
