Increasing Influenza and Tdap Vaccination of Pregnant Women

Pregnant women who get influenza are more likely than non-pregnant women to have serious complications, including hospitalizations, death, preterm labor and premature birth. Pertussis can cause hospitalization or death for newborns. However, influenza and Tdap vaccination rates for pregnant women are low nationally. In this study, the investigators will perform a randomized controlled trial aimed at practice change in obstetricians\' offices, with an overall goal of reducing morbidity and mortality from influenza and pertussis infections.
