The Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices and the American College of Obstetricians and Gynecologists recommend that all adults receive an annual influenza vaccine. Influenza vaccination is an essential element of preconception, prenatal, and postpartum care because pregnant women are at an increased risk of serious illness due to seasonal and pandemic influenza. Since 2010, influenza vaccination rates among pregnant women have increased but still need significant improvement. It is particularly important that women who are or will be pregnant during influenza season receive an inactivated influenza vaccine as soon as it is available. It is critically important that all obstetrician-gynecologists and all providers of obstetric care advocate for influenza vaccination, provide the influenza vaccine to their pregnant patients, and receive the influenza vaccine themselves every season. It is imperative that obstetrician-gynecologists, other health care providers, health care organizations, and public health officials continue efforts to improve the rate of influenza vaccination among pregnant women.
