  • Publication number: 20070231340
    Abstract: An immunogenic composition having 13 distinct polysaccharide-protein conjugates and optionally, an aluminum-based adjuvant, is described. Each conjugate contains a capsular polysaccharide prepared from a different serotype of Streptococcus pneumoniae (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F and 23F) conjugated to a carrier protein. The immunogenic composition, formulated as a vaccine, increases coverage against pneumococcal disease in infants and young children globally, and provides coverage for serotypes 6A and 19A that is not dependent on the limitations of serogroup cross-protection. Also described is a method for making an immunogenic conjugate comprising Streptococcus pneumoniae serotype 3 polysaccharide covalently linked to a carrier protein, the method including periodic acid oxidation of the polysaccharide in the presence of bivalent cations.

Methods for making an immunogenic conjugate comprising Streptococcus pneumoniae serotype 19A polysaccharide are also provided in which the serotype 19A polysaccharide is co-lyophilized with a carrier protein and conjugation is carried out in dimethyl sulfoxide (DMSO) via a reductive amination mechanism.

  • Patent number: 7223411
    Abstract: A herpesvirus vaccine comprising a mutated herpesvirus suspended in a pharmaceutically acceptable carrier. The mutated herpesvirus is capable of infecting cells of the mammal to be vaccinated, but incapable of completing a replicative cycle, and it is capable of eliciting a protective immune response in that mammal. The mutated herpesvirus is also capable of treating immunomodulatory or immunoregulatory diseases. The mutation occurs in at least one gene encoding a protein essential for replication of the virus, so that the mutation renders the virus replication defective.
