-34. (canceled)
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;
- and
- 2) incubating the egg for a predetermined period of time to replicate the virus.
