Dear Dr. Husam Bakri, appreciate your efforts. Thanks & Regards.

Good day, Dr. H Bakri: AI H9 is endemic in the area, I think it is playing a role in hindering ND & I.B variants - vaccinations ( i.e vaccines failures ) , due to high pressure in the field early exposure to the virus leads to interference & immune - suppression , in that situation advice on bio-security is a high priority & not to blame vaccines & vaccinations.Regards.

Thanks a lot for your kindness & good will , Dr. Bakri , my e - mail reads as follows : msiddig50@hotmail.com , with best wishes ...

Good Morning , Dr. Husam Bakri -( MSD ) - Many thanks for your immediate response . Kindly requested to provide us ( if possible) with those cross protection studies of I.B variants done in Emirates ( if any ), with kind regards

Dear, Dr. Husam Bakri - ( M SD) - The ProtectotypeTM Concept may not give full protection in the event of the presence of a complex of mixed strains of .I.B variants . I think why not to include extra I.B variant vaccines with homologous strains prevalent in the area to the program to broaden/ increase the level of protection .

Many thanks to Dr. Husam Bakri ( MSD ) - As we all know - Avian influenza strain H9 - , is endemic in the middle east area . I think we need to discuss & rule out the - Role of the presence of Avian Influenza H9 strain - on failure of vaccinations against I.B - Variants & Newcastle diseases , . . . (Interference & Immune suppression , . . .ect )
