Author/s : Dr. Husam Bakri. / Technical and Pharmacovigilance, Manager, MSD Middle East - Dubai.

Introduction Infectious bronchitis (IB) virus, first described in the 1930s (Schalk & Hawn, 1931), continues to be a major cause of disease in chickens of all ages and types in all parts of the world (Anon, 1988, 1991).

Salam,
We are advising the following vaccination program to cover ND , IB and AI sure gumboro is included but the time of Gumboro vaccination deepened on MDA:
- Day one Ma5+Clone30 Spray course
ND+AI killed at day one.
14-16 days Clone30+IB 4/91 spray.
The above vaccination program gave excellent results.
We do have emergency vaccination program against IB specially when we get variant IB at early age we advise the following:
MA5+4/91 at day one
Ma5+Clone30 at day 14 .


Hope this will help you according to your area.

All the best

Bakri

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 .

Salam Dr.
We have done more than 30 cross protraction study with 30 variants strain are playing a role over the world incloding Middle East . Results showed very good protection level for these strains . We strongly believe that program can give very good results . The most important is to control other diseases are playing a role .
All the best

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.

Thank you, Dr. Hussam Bakri. What is your idea about use 4./91 or 4/91+clon30 in 1 day old? Isn't this strong for 1 day old or we can do? What is your idea about reverse vaccine strain to wild strain with high usage of ib vaccines?

Dear Dr. Bahram ,
First thank you very much for your comment and question.
1- Using IB 4/9 + Clone30 at day one 100% is ok . in the middle east we are using it since we started to have early IB variant challenge as you know ND also is challenging at early age that why they need to cover IB and ND from the first day.
2- As you know vaccines before be in the market , safety study is one from the major point has to be clear to avoid the point you mentioned and I am sure most of the good companies do that .

Hope I could cover your points.

All the best

Bakri
