Introduction: Infants ≤2 months are at greatest risk for morbidity/mortality from pertussis. Tdap vaccines given in late pregnancy or postpartum can protect infants from pertussis. Pregnancy increases risks for maternal and perinatal complications. Influenza vaccine (FLUV) given in pregnancy can protect women and newborns.

Objectives: To determine Tdap and FLUV rates in pregnant and postpartum patients and identify factors associated with vaccination.

Methods: Miami Valley Hospital delivery records from 01/2009-12/2011 were retrospectively reviewed. Data reviewed included age, insurance, race/ethnicity, and county of residence. Descriptive statistics analyzed prevalence of immunization, timing, and demographics. Chi-square and odds ratios detected differences between characteristics.

Main Findings:A total of 13704 charts were reviewed. Tdap was administered to 42%, with 93% vaccinated within 10 days after birth. Tdap uptake was significantly greater among younger mothers (49%, p=0.023), those with government insurance (48%, p

Conclusions: Despite current recommendations, only a minority received vaccinations during pregnancy or postpartum. Vaccination rates increased over time and with certain demographics. Improved strategies may increase FLUV and Tdap administration in this population.
