  Purpose

The purpose of this study is to evaluate the immunogenicity and safety of an inactivated, non adjuvanted A(H1N1)v influenza vaccine in 120 pregnant women.

Study procedures will include 2 doses of vaccine, blood samples, cord blood samples at delivery and recording temperature and vaccine side effects in a memory aid for 7 days following each vaccination. Participants will be involved in study related procedures about 3 at 5 months.

Primary Outcome Measures:
  • Immunogenicity: proportion of subjects achieving a serum HAI antibody titer of greater than or equal to 1:40, proportion of subjects with 4-fold or greater HAI antibody titer increases against H1N1 2009 virus following H1N1 vaccine. [ Time Frame: Day 21 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Safety: occurence of local and systemic adverse events [ Time Frame: Throughout the course of the study ] [ Designated as safety issue: Yes ]
  • Immunogenicity: proportion of subjects achieving a serum HAI antibody titer of greater than or equal to 1:40, proportion of subjects with 4-fold or greater HAI antibody titer increases against H1N1 2009 virus following H1N1 vaccine. [ Time Frame: Day 42 and at delivery ] [ Designated as safety issue: No ]
  • Safety:occurence of vaccine-associated serious adverse events [ Time Frame: Throughout the course of the study ] [ Designated as safety issue: Yes ]
