The present invention relates to a process for stabilizing an adjuvant containing vaccine composition, an adjuvanted vaccine composition in dry form and in particular a process for stabilizing an influenza vaccine composition, particularly an adjuvanted influenza vaccine composition in dry form.

The present invention relates to methods of replicating viruses in vitro. In particular, the invention relates to a genetically modified population of cells, and/or a population of cells treated with an exogenous compound, wherein the cells are capable of producing more virus than cells lacking the genetic modification and/or lacking treatment with the exogenous compound. The invention also relates to methods of producing populations of such cells, as well as the use of the viruses obtained to prepare vaccine compositions.

The present invention provides antibodies that bind to the cat allergen, Fel d1, compositions comprising the antibodies, nucleic acids encoding the antibodies and methods of use of the antibodies. According to certain embodiments of the invention, the antibodies are fully human antibodies that bind to Fel d1. The antibodies of the invention are useful for binding to the Fel d1 allergen in vivo, thus preventing binding of the Fel d1 allergen to pre-formed IgE on the surface of mast cells or basophils. In doing so, the antibodies act to prevent the release of histamine and other inflammatory mediators from mast cells and/or basophils, thus ameliorating the untoward response to the cat allergen in sensitized individuals. The antibodies of the invention may also be useful for diagnostic purposes to determine if a patient is allergic to the Fel d1 cat allergen.

The development of a computationally optimized influenza HA protein that elicits broadly reactive immune response to all H5N1 influenza virus isolates is described. The optimized HA protein was developed through a series of HA protein alignments, and subsequent generation of consensus sequences, for clade 2 H5N1 influenza virus isolates. The final consensus HA amino acid sequence was reverse translated and optimized for expression in mammalian cells. Influenza virus-like particles containing the optimized HA protein are an effective vaccine against H5N1 influenza virus infection in animals.

Provided herein are compositions related to vaccines, e.g., influenza vaccines, including, peptide based vaccines, nucleic acid based vaccines, recombinant virus based vaccines, antibody based vaccines, and virus based vaccines. Also provided herein are methods related to vaccines, e.g., influenza vaccines, including methods of identifying epitopes for the vaccines, producing, formulating, and administering the vaccines.

Nanoparticles and vaccines containing these nanoparticles that elicit an immune response against hemagglutinin (HA) proteins from a broad range of influenza viruses are provided. The nanoparticles are made from self-assembling proteins, at least one of which is joined to an immunogenic portion of an influenza HA protein. This immunogenic portion is displayed on the nanoparticle surface, making the nanoparticles useful for vaccinating subjects against influenza virus.
