摘要:
A vaccine containing a H1 subtype influenza A virus hemagglutinin is adjuvanted with an oil-in- water emulsion adjuvant. The vaccine is suitable for immunizing a patient against the virus referred to as 'swine flu'. The vaccine may be monovalent. The vaccine may include two different H1 subtype influenza A virus hemagglutinins, wherein (i) the first H1 subtype influenza A virus hemagglutinin is more closely related to SEQ ID NO: 1 than to SEQ ID NO: 3 and (ii) the second H1 subtype influenza A virus hemagglutinin is more closely related to SEQ ID NO: 3 than to SEQ ID NO: 1. A monovalent vaccine may be administered in conjunction with a trivalent A/H1N1-A/H3N2- B seasonal influenza vaccine.
摘要:
The present application pertains to a composition, comprising (a) amphipathic peptides; (b) lipids and (c) at least one immunogenic species. Respective compositions are suitable for immunogenic species transport and delivery, for example for systemic or local delivery to a mammal. Also provided are pharmaceutical compositions, comprising respective compositions. Methods of forming the foregoing are also provided.
摘要:
The invention quantifies HA using a process which comprises two key steps: HA is captured using a lectin, such as snowdrop lectin; and captured HA is quantified using an immunoassay. This assay can conveniently be performed in an ELISA format. The process is specific, is robust in the face of contaminants, and is more rapid and more sensitive than the standard SRID assay.

Expression of a transgene is driven in a host cell using a pol I promoter which is not endogenous to an organism from the same taxonomic order from which the host cell is derived.
摘要:
A first antigen is administered to a subject to select progenitor B cells that are suitable for subsequent production of a desirable affinity-matured antibody, and then a second antigen is administered to stimulate the expansion of B cells that produce that affinity-matured antibody. An immunization protocol is used in which two different antigens are administered (usually in series, but in some embodiment simultaneously), where the first antigen elicits an efficient germline antibody response and the second antigen elicits an efficient and desired affinity-matured antibody response.
摘要:
The invention relates to chimeric norovirus VP1 proteins containing the S-domain of VP1 of a first norovirus strain and a P-domain that contains at least a portion of the P-domain of VP1 of a second norovirus strain. The invention also relates to nucleic acids that encode the chimeric VP1 proteins, virus-like particles that contain a chimeric norovirus VP1 protein, and to immunogenic compositions.
