Abstract: The present invention relates to polyclonal antibodies for use in the prevention and/or treatment of the Ebola virus disease. In one embodiment, the polyclonal antibodies are specific for a truncated Ebola virus GP glycoprotein. Said polyclonal antibodies are preferably non-human antibodies and are provided in a serum free pharmaceutical composition. The present invention also relates to a method of prevention and/or treatment of Ebola virus disease in a subject in need thereof, comprising administering to said subject polyclonal antibodies specific for the Ebola virus.

Abstract: An immunogenic product including IFN? coupled to a carrier protein molecule is capable to induce in vivo anti-IFN? antibodies and is useful in treating IFN? related conditions.

Abstract: An immunogenic product includes TNF? coupled with KLH, wherein the TNF? is strongly inactivated, which means that the product shows less than 30% of cytolytic activity and/or an inactivation factor of more than 15000, in the conditions of TEST A. An emulsion and a vaccine including the immunogenic product and methods for preparing the immunogenic product are also described.

Abstract: Stabilizers for live vaccines and attenuated mono- or multivalent live vaccines, stabilized vaccines containig such stabilizers, and methods for preparing such vaccines, are disclosed. Said stabilizers for vaccines containing one or more attenuated live viruses include one or more components selected from each of the following groups: amino acids, disaccharides, polyalcohols and buffer solutions, with the proviso that one component selected from the disaccharide group is saccharose.

Abstract: A method is disclosed for industrially producing a Japanese encephalitis vaccine, wherein (a) cells from a cell line are cultured, (b) the resulting cell culture is inoculated with a Japanese encephalitis virus in the presence of a viral growth medium, (c) the virus is propagated and multiplied on the cells, (d) the viral growth medium is recovered in the form of a suspension of viruses produced by the cells, (e) the virus suspension is purified in at least one ion exchange chromatography step and a gel permeation step, and (f) the virus suspension is formulated and converted into a pharmaceutical form to preserve it until the moment of use. A Japanese encephalitis vaccine characterised in that it comprises a Japanese encephalitis virus produced by culturing cells from a cell line, and in that the cellular DNA content is less than 100 pg/dose, is also disclosed.

Abstract: A method for purifying viruses from a cell line culture by chromatography, comprising an anion exchange chromatography step followed by a cation exchange chromatography step and optionally a metal-binding affinity chromatography step. The method is particularly suitable for producing viruses for use in vaccines.

Abstract: Process for preparing hepatitis A (HAV) antigens and vaccines.The HAV virus is multiplied on competent cells, the infected cells are lysed, the supernatant is recovered and the purification is carried out by a chromatographic procedure on an anion-exchange support and a gel filtration procedure, the purification procedures being carried out in the presence of a detergent, and the chromatographic procedure being carried out under conditions which retain the virions or viral capsids, which are then eluted.
