Abstract:
The invention improves TdaP vaccines by including a TLR agonist in them. This agonist can provide stronger protection, longer-lasting protection, and/or can reduce the amount of antigen which is required to achieve a particular immune response.
Abstract:
Elimination of disulphide bond formation of cysteine-containing S.aureus antigens enhances antigen stability. The invention provides a composition comprising variant forms of cysteine-containing S.aureus antigen with a point mutation that replaces, deletes or modifies the cysteine residue.
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:
An immunogenic composition comprising a diphtheria toxoid, a tetanus toxoid, a pertussis toxoid, an aluminium salt adjuvant, and a TLR4 agonist. Preferably, the TLR4 agonist and/or at least one of the toxoids is/are adsorbed to the aluminium salt adjuvant.
