Patent

CA 2392653

Novel means and methods are provided for the production of mammalian viruses, comprising infecting a culture of immortalized human cells with the virus, incubating the culture infected with virus to propagate the virus under conditions that permit growth of the virus, and to form a virus-containing medium, and removing the virus-containing medium. The viruses can be harvested and be used for the production of vaccines. Advantages - human cells of the present invention can be cultured under defined serum free conditions, and the cells show improved capability for propagating virus. In particular, methods are provided for producing in cultured human cells Influenza virus and vaccines derived thereof. This method eliminates the necessity to use whole chicken embryos for the production of Influenza vaccines. The method provides also for the continuous or batchwise removal of culture media. As such, the present invention allows the large scale continuous production of viruses to a high titer.

L'invention concerne de nouveaux moyens et procédés de fabrication de virus mammaliens qui consistent en ce qui suit: infecter une culture de cellules humaines immortalisées avec le virus, incuber la culture infectée avec le virus pour assurer la propagation du virus dans des conditions permettant la croissance du virus et former un support contenant la virus puis évacuer le support contenant la virus. Les virus peuvent être recueillis et utilisés dans la production de vaccins. Les avantages consistent en ce qu'il est possible de cultiver les cellules humains dans des conditions définies, sans sérum, et les cellules manifestent une capacité améliorée d'assurer la propagation du virus. L'invention concerne notamment des procédés pour produire dans les cellules humaines de culture le virus d'Influenza virus et les vaccins dérivés de ce virus. Le procédé élimine le besoin d'utiliser des embryons de poules entiers dans la production de vaccins contre l'Influenza. Le procédé permet aussi de récupérer le milieu de culture de façon continue et par lots. La présente invention permet de fabriquer des virus en continu à large échelle, avec un titre plus élevé.
