Yellow Fever Virus Vaccine and Immune Globulin Study - Full Text View

Sponsor:	Emory University
Collaborators:	sanofi pasteur Centers for Disease Control and Prevention
Information provided by:	Emory University
ClinicalTrials.gov Identifier:	NCT00254826

Purpose

The purpose of this study is to determine whether immune globulin can limit the amount of yellow fever vaccine virus present in the blood after vaccination without compromising the immunity associated with the yellow fever vaccine. The study will enroll 80 participants in two groups of 40 each. The first group will receive the yellow fever vaccine with salt-water placebo. The second group will receive yellow fever vaccine with immune globulin. The amount of vaccine virus and immune response in both groups will be compared. Yellow fever vaccine has been used to protect humans against Yellow Fever Vaccine disease since the 1930s.

Primary Outcome Measures:

Compare the proportion of participants developing viremia between the group receiving the yellow fever vaccine/saline and yellow fever vaccine with human immune globulin.
Characterize the dynamics of T cell activation, cytokine response and dendritic cell response in vaccinees during primary response to the yellow fever vaccine and yellow fever vaccine in combination with human immune globulin.
Compare the proportion of subjects in each group that seroconverts in the group of vaccinees without prior yellow fever immunity.

Secondary Outcome Measures:

Compare the viremia levels between the group of vaccinees receiving yellow fever vaccine with the group receiving yellow fever vaccine with human immune globulin.
Compare the dynamics of T cell activation, cytokine response and dendritic cell response in vaccinees during primary response to yellow fever vaccine to vaccinees given yellow fever vaccine given in combination with human immune globulin.
Compare the geometric mean neutralizing antibody titer in the group of yellow fever vaccinees with the group of vaccinees receiving yellow fever vaccine in combination with human immune globulin.
