Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Pregnant women have increased morbidity and mortality due to infection with influenza. Changes in T cell function have been proposed as possible mechanisms for this finding. We believe that pregnancy induced changes in NK cell phenotype and function also impact influenza immunity. This study will compare the immune response of pregnant women and controls to TIV influenza vaccination as a surrogate for infection. In addition pregnant women with flu like illness will be enrolled to evaluate changes in immune response following influenza infection as compared to vaccination.
