Influenza Vaccine Coverage among Pregnant Women in a Public Hospital System during the 2009-2010 Pandemic Influenza Season

الملخص EN

The purpose of this study was to compare influenza vaccination rates of pregnant women in a public safety-net health system to national coverage rates during the 2009-2010 pandemic influenza season.

A chart review of a random sample of deliveries was undertaken to determine rates of coverage and predictors of vaccine coverage of women who obtained prenatal care and delivered in our health system.

Rates were calculated from deliveries from when the vaccine was first available through April 30, 2010.

Coverage rates were 54% for the seasonal influenza vaccine and 51% for the H1N1 vaccine.

Race/ethnicity, insurance status and language spoken did not predict the receipt of either vaccine.

When we included only births which occurred through March 12, 2010, as was done in a large population-based study, the rates were 61% and 59%, respectively.

Our rates are about 10% higher than the rates reported in that study.

Our comprehensive strategy for promoting vaccine coverage achieved higher vaccination rates in a safety-net health system, which serves groups historically less likely to be vaccinated, than those reported for the pregnant population at large.
