The present invention relates to modified avian eggs which can be used to produce increased levels of virus. The present invention also relates to methods of producing viruses in avian eggs of the invention, as well as the use of the viruses obtained to prepare vaccine compositions. 134.-. (canceled)35. A method of replicating a virus , the method comprising;1) inoculating an avian egg with a virus, wherein the avian egg comprises a genetic modification which reduces expression of an antiviral gene in the Type I interferon pathway in the egg when compared to an isogenic egg lacking the genetic modification, wherein the egg is capable of producing more virus than the isogenic egg; and2) incubating the egg for a predetermined period of time to replicate the virus.36.
