  • Patent number: 7179457
    Abstract: The invention provides a nodavirus RNA1 molecule modified to include a heterologous insertion which is downstream of its replicase ORF and, preferably, its B2 ORF. The insertion preferably comprises one or more protein-coding regions. The modified RNA1 may be packaged in a VLP, such as a papillomavirus VLP. The small size of nodavirus RNA1 makes it ideal for HPV packaging.

  • Patent number: 6855321
    Abstract: The invention relates to polyepitope carrier proteins that comprise at least five CD4+ T cell epitopes, for conjugation to capsular polysaccharides. The carrier proteins are use useful as components of vaccines that can elicit a T-cell dependent immune response. These vaccines arm particularly useful to confer protection against infection from encapsulated bacteria in infants between the ages of 3 months and about 2 years.

  • Patent number: 6638513
    Abstract: The present invention pertains generally to Neisseria meningitidis serogroup B glycoconjugates. More particularly, the invention pertains to glycoconjugates formed from a Neisseria meningitidis serogroup B capsular oligosaccharide derivative (MenB OS derivative) in which sialic acid residue N-acetyl groups are replaced with N-acyl groups. The invention also pertains to vaccine formulations containing the glycoconjugates, methods of making the vaccine formulations, and methods of using the vaccine formulations to treat or prevent Neisseria meningitidis serogroup B or E. coli K1 disease in a mammalian subject.
