74results about "Diphtheria-tetanus-pertussis combination vaccine" patented technology

Various improvements to vaccines that include a serogroup C meningococcal conjugate antigen, including: (a) co-administration with acellular B. pertussis antigen; (b) co-administration with an inactivated poliovirus antigen; (c) supply in a kit together with a separate pneumococcal conjugate component, which may be in a liquid form; and (d) use in combination with a pneumococcal conjugate antigen but without an aluminum phosphate adjuvant. A kit may have: (a) a first immunogenic component that comprises an aqueous formulation of a conjugated capsular saccharide from Streptococcus pneumoniae; (b) a second immunogenic component that comprises a conjugated capsular saccharide from Neisseria meningitidis serogroup C.

In one aspect, the invention relates to a composition including a first polypeptide having the sequence set forth in SEQ ID NO: 1 and a second polypeptide having the sequence set forth in SEQ ID NO: 2. In one embodiment, the composition includes about 120 μg / ml of a first polypeptide including the amino acid sequence set forth in SEQ ID NO: 1, 120 μg / ml of a second polypeptide including the amino acid sequence set forth in SEQ ID NO: 2, about 2.8 molar ratio polysorbate-80 to the first polypeptide, about 2.8 molar ratio polysorbate-80 to the second polypeptide, about 0.5 mg / ml aluminum, about 10 mM histidine, and about 150 mM sodium chloride. In one embodiment, a dose of the composition is about 0.5 ml in total volume. In one embodiment, two-doses of the composition induce a bactericidal titer against diverse heterologous subfamily A and subfamily B strains in a human.

A multi-component vaccine composition is described comprising acellular pertussis vaccine components, diphtheria toxoid, tetanus toxoid and inactivated poliovirus. The composition also may contain a conjugate of a capsular polysaccharide of Haemophilus influenzae type b and tetanus toxoid or diphteria toxoid, which may be reconstituted from a lyophilized state by the other components of the vaccine. The administration of the multiple component vaccine results in no diminution in the immunogenicity of any component as a result of interference by other components of the vaccine.

Vaccines have been studied that comprise (a) D-T-Pw-HepB-Hib antigens and (b) one or more meningococcal conjugate antigens. A number of improvements and variations of these vaccines have been discovered. The vaccines can be prepared extemporaneously at the time of use by mixing together two components: (a) a first component comprising D, T, wP and HBsAg antigens; and (b) a second component comprising a Hib conjugate and one or more meningococcal conjugates.

The present invention relates to the field of vaccines for protecting against polio, and in particular to combination vaccines for protecting against polio, diphtheria, tetanus, and pertussis diseases. Specifically, vaccines comprising reduced dose inactivated poliovirus are provided

The invention provides a process for producing a combined vaccine containing an inactivated Sabin strain of poliovirus, a Bordetella pertussis protective antigen, a diphtheria toxoid and a tetanus toxoid, the process including a step of producing a high-titer Sabin strain poliovirus. The inventive process for producing a combined vaccine, including a step of culturing, in the presence of from about 4 g / L to about 6 g / L of a microcarrier, Vero cells to be inoculated with a Sabin strain of poliovirus, is useful as a process for efficiently producing a combined vaccine containing an inactivated Sabin strain of poliovirus.

A liquid D-T-Pa component is used to reconstitute a lyophilised meningococcal component, thereby producing a combined vaccine.

The present invention relates to a method for the production of a hepatitis B antigen suitable for use in a vaccine, the method comprising purification of the antigen in the presence of cysteine, to vaccines comprising such antigens.

The present invention provides methods and compositions to induce neutralizing antibodies in mammals to serotypes of dengue virus, measles virus, mumps virus, rubella and / or VZV virus.

In one aspect, the invention relates to a composition including a first polypeptide having the sequence set forth in SEQ ID NO: 1 and a second polypeptide having the sequence set forth in SEQ ID NO: 2. In one embodiment, the composition includes about 120 μg / ml of a first polypeptide including the amino acid sequence set forth in SEQ ID NO: 1, 120 μg / ml of a second polypeptide including the amino acid sequence set forth in SEQ ID NO: 2, about 2.8 molar ratio polysorbate-80 to the first polypeptide, about 2.8 molar ratio polysorbate-80 to the second polypeptide, about 0.5 mg / ml aluminum, about 10 mM histidine, and about 150 mM sodium chloride. In one embodiment, a dose of the composition is about 0.5 ml in total volume. In one embodiment, two-doses of the composition induce a bactericidal titer against diverse heterologous subfamily A and subfamily B strains in a human.

An injectable immunogenic composition comprising capsular saccharides from at least two of serogroups A, C, W135 and Y of Neisseria meningitidis, wherein said capsular saccharides are conjugated to carrier protein(s) and / or are oligosaccharides, and wherein (i) the composition comprises <50 μg meningococcal saccharide per dose, and / or (ii) the composition further comprises an antigen from one or more of (a) serogroup B N. meningitidis; (b) Haemophilus influenzae type B; and / or (c) Streptococcus pneumoniae. Saccharide antigens in the compositions are generally conjugated to a carrier.
