Abstract: The present invention relates to an immunogenic composition for raising an immune response to an antigen, the composition comprising the antigen and a targeting moiety specific for lymph-resident dendritic cells. Use of the immunogenic composition in a vaccine and methods of boosting an immune response using the composition are also provided. Conversely, the invention also relates to immunogenic composition for raising an immune response to an antigen, the composition comprising the antigen and a targeting moiety specific for tissue-derived dendritic cells and a vaccine comprising said composition.

Abstract: An optical light diffuser providing a generally cylindrical pattern of light emission. The diffuser is formed from an optical fiber operable to transmit the optical radiation from its proximal end to its distal end and having a guiding core and a cladding surrounding the core. The optical fiber has an abraded section at its distal end that allows light to escape uniformly over the abraded section forming a generally cylindrical pattern of diffuse light that surrounds the distal end of the optical fiber.
