Abstract:
NMB1870 is a protein in Neisseria meningitidis. Three families of NMB1870 are known. To increase the ability of a NMB1870 protein to elicit antibodies that are cross-reactive between the families, NMB1870 is engineered. Sequences can be substituted from one NMB1870 family into the corresponding position in another family. Proteins of NMB1870 sequences from different families can be joined to each other.
Abstract:
The efficacy of S. pneumoniae vaccines can be enhanced by adjuvanting S. pneumoniae saccharide and/or protein antigens with a mixture of a TLR agonist (preferably a TLR7 agonist) and an insoluble metal salt (preferably an aluminium salt). The TLR agonist is typically adsorbed to the metal salt. The S. pneumoniae antigen can also be adsorbed to the metal salt.
Abstract:
fHBP is a protein in Neisseria meningitidis. Three families of fHBP are known. To increase the ability of a fHBP protein to elicit antibodies that are cross-reactive between the families, fHBP is selected or engineered to have a sequence which can elicit broad-spectrum bactericidal anti-meningococcal antibodies after administration to a host animal.
