Abstract
The present invention relates to immunization of hypo-responsive groups of individuals. In particular, the present invention provides methods and compositions for eliciting a potent immune response to hepatitis B virus in individuals in need thereof.
Claims14
A method for eliciting a seroprotective immune response against hepatitis B virus (HBV) in a human subject with chronic kidney disease under a vaccination schedule, comprising:
- administering to the human subject a first, second and third dose of an immunogenic composition comprising a hepatitis B surface antigen (HBsAg) and an immunostimulatory sequence (ISS) present in the immunogenic composition in amounts effective to elicit a seroprotective immune response comprising an anti-HBsAg concentration of at least 10 mIU/mL in the subject at one month after only three doses,
- wherein said ISS is single stranded and consists of the nucleotide sequence of SEQ ID NO:1, and wherein said immunogenic composition comprises from about 10 to about 20 μg of said HBsAg and from about 1000 to about 3000 μg of said ISS.
A method for eliciting a durable immune response against hepatitis B virus (HBV) in a human subject with chronic kidney disease under a vaccination schedule, comprising:
- administering to the human subject a first, second and third dose of an immunogenic composition comprising a hepatitis B surface antigen (HBsAg) and an immunostimulatory sequence (ISS) present in the immunogenic composition in amounts effective to elicit a durable immune response comprising an anti-HBsAg concentration of at least 100 mIU/mL in the subject at 28 weeks after only three doses,
- wherein said ISS is single stranded and consists of the nucleotide sequence of SEQ ID NO:1, and wherein said immunogenic composition comprises from about 10 to about 20 μg of said HBsAg and from about 1000 to about 3000 μg of said ISS.
