...Vaccines against both viruses would benefit from improvements that would allow them to be more cost-effective, provide higher immune protection, and decrease the risk of disease development by ensuring complete virus inactivation without affecting the antigens responsible for inducing the immune response [36,37]....

...Whereas members of class I isolates are grouped into only one genotype, isolates belonging to class II are further subdivided into genotypes IXVIII which are all predicted to be virulent in chicken, except some isolates in genotypes I, II, and X [21, 22]....

...In fact, there are indications that the replication and shedding of the virulent virus can be substantially reduced when much higher doses of the live vaccines are administered [21, 22]....

...During the late 1990’s, reverse genetics technology was developed to rescue infectious NDV from assembled sub-genomic overlapping cDNA fragments under control of a T7 RNA polymerase promoter (Peeters et al., 1999; Romer-Oberdorfer et al., 1999)....

...Inactivated vaccines became commercially available in the USA in 1945, but were not adopted by the poultry industry at that time as they were comparatively expensive, and were unable to prevent clinical disease to a sufficient level to merit wide spread use....

...However, it is likely that all bird species are susceptible to infection with NDV strains, and to date, more than 236 avian species have been documented with NDV infections (Kaleta and Baldauf, 1988)....
