Abstract
Abstract This invention pertains to immunogenic conjugates comprising a carbohydrate containing antigen or other antigen bound to or genetically fused with a cytokine, lymphokine, hormone or growth factor having immunomodulating activity, wherein the cytokine, lymphokine, hormone or growth factor is capable of modifying immunogenicity of the carbohydrate containing antigen. The cytokine or lymphokine can be an interleukin or an interferon. The immunogenic conjugate can be used in vaccine and co-vaccine formulations.
