I fully agree that broiler vaccination with inactivated vaccines is not the preferred way. However, as you know at this stage we do not have any live H9N2 vaccine and our only option is to use the inactivated vaccine. The usage of the inactivated vaccine in broilers together with the selection of the right clade solved the issue of H9N2 in Israel. Still you need to take into account that early vac ...

Vaccination of Broilers with an inactivated vaccine is not very effective due to the very high maternal antibodies ...

I agree with Dr Decanini Vaccination of broilers with maternal antibodies is not effective. Birds with MDA should be vaccinated when titre decrease to HI 3-4, otherwise the vaccine will not penetrate. I found it strange that a strain from 1998 is still protective. in all the work done in Israel it was clearly demonstrated that the 2001 isolate used in the first H9 vaccine had to be replaced af ...

Great review and discussion, Interesting to see that the prevalence of Serovar C3 is increasing. C3 is very pathogenic and damages and production losses are very high compared to C2 , B, and A Serovars. Israel, Russia, Ukraine and South Africa, are using commercial C3 vaccines which also cross protect with Serovar C2. The disease is under control if vaccination program is implemented prop ...
