  • Method for Producing the Flu Virus
    Publication number: 20110212129
    Abstract: The invention relates to a method for producing flu virus according to which: a) immunizing a hen by administering a flu vaccine to the hen, b) triggering embryogenesis in one or more eggs of the immunized hen, c) infecting the one or more embryonated eggs by inoculating a flu virus into the allantoic cavity of the eggs, d) incubating the one or more infected embryonated eggs under temperature and humidity conditions that allow replication of the virus, and e) harvesting the allantoic fluid of the one or more incubated eggs containing the virus.

  • Titration method for a complex viral composition
    Patent number: 6890711
    Abstract: The invention concerns a method for determining, in a composition containing different species of types of live viruses, the amount of viruses of each type or species, consisting in the following steps: propagating viruses of each type or species on cells permissive to the viruses but not inducing viral interference, assaying each type or species of virus using a specific monoclonal antibody.

  • Method for preparing an influenza virus, antigens obtained and applications thereof
    Patent number: 6048537
    Abstract: Method for preparing purified influenza antigens from a fluid containing influenza virus, comprising the steps of concentration, purification, fragmentation and, where appropriate, inactivation, characterized in that:A. either the purification step entails several ultracentrifugation steps separated by a filtration step,B. or the fragmentation step is performed on the live virus in the presence of an amphiphilic nonionic detergent, followed by a removal of undesirable substances by filtration, retaining all of the viral constituents,or these two steps are carried out in any order.
