The present invention relates to a polypeptide comprising a mutant fragment of an outer surface protein A (OspA), a nucleic acid coding the same, a pharmaceutical composition (particularly for use as a medicament of in a method of treating or preventing a Borrelia infection) comprising the polypeptide and/or the nucleic acid, a method of treating or preventing a Borrelia infection and a method of immunizing a subject.

Provided is an immunogenic composition including a peptide, wherein consecutive amino acids of the peptide include at least amino acids 186-193 of SEQ ID NO:1 and one or more adjuvants. In an example, the peptide is covalently linked to an amino acid sequence including SEQ ID NO:2. Also provided is a method of vaccinating a subject against Borrelia burgdorferi, including administering to the subject an effective amount of the immunogenic composition.

The present invention relates to an immunogenic polypeptide, a nucleic acid encoding the same, a pharmaceutical composition comprising the same and the immunogenic polypeptide, nucleic acid or pharmaceutical composition for use as a medicament, particularly a vaccine, or for use in a method of treating or preventing a Borrelia infection.

Heptose-1-monophosphate-7-derivatives are modifiable immunomodulators that can be used to prepare clinically active conjugate compounds. Such conjugate compounds are useful in modulating an immune response in a subject.

Provided herein are recombinant Factor H Binding Protein B (FhbB) chimeric proteins comprising several different mutant variants of the Treponema denticola Factor H binding protein B (FhbB). The mutant variants cannot bind Factor H. The chimeric proteins are used to vaccinate subjects against periodontal disease either systemically and/or by direct application of antibodies generated against the chimeric proteins to the oral cavity (e.g. the gums) of a patient to prevent and/or treat periodontal disease.

This invention relates to a method of treating a dog for canine diseases comprising administering to the dog therapeutically effective amounts of a vaccine, wherein the vaccine comprises viral antigens, a bacterin, or both, and wherein the vaccine is administered subcutaneously or orally according to the schedules provided herein.

The present invention relates to a polypeptide comprising a mutant fragment of an outer surface protein A (OspA), a nucleic acid coding the same, a pharmaceutical composition (particularly for use as a medicament of in a method of treating or preventing a Borrelia infection) comprising the polypeptide and/or the nucleic acid, a method of treating or preventing a Borrelia infection and a method of immunizing a subject.

Provided is an immunogenic composition including a peptide, wherein consecutive amino acids of the peptide include at least amino acids 186-193 of SEQ ID NO:1 and one or more adjuvants. In an example, the peptide is covalently linked to an amino acid sequence including SEQ ID NO:2. Also provided is a method of vaccinating a subject against Borrelia burgdorferi, including administering to the subject an effective amount of the immunogenic composition

The present invention provides highly efficient methods, and compositions related thereto, for generating high titer human antibodies or antibody fragments thereof in a mammalian subject. The methods comprise administering a virus or virus-like particle to a mammal comprising heterologous immune cells and isolating a population of immunoglobulin-producing cells from the mammal, thereby producing the antibodies or antibody fragments thereof.

Provided is an immunogenic composition including a peptide, wherein consecutive amino acids of the peptide include at least amino acids 186-193 of SEQ ID NO:1 and one or more adjuvants. In an example, the peptide is covalently linked to an amino acid sequence including SEQ ID NO:2. Also provided is a method of vaccinating a subject against Borrelia burgdorferi, including administering to the subject an effective amount of the immunogenic composition.
