You have to be carefully in combining different type of activated vaccines are not the antigens but the emulsion(Adjuvant) be may not compatible,
What do you mean with:" after gap of 40-50" ?

Puneet JindalI am not related to CEVA but according me there would be no any problem to combine the rHVT/H5 with SB1 .

I agree with comments made by Michel
Mixing any recombinantHVT vector vaccine with a conventional HVT vaccine will interfere with the protection of the insert like in your case with the AI/H5 protection
As mentioned will not effect the MD protection
To improve protection of the recombinant for MD you can if manufacture recommend to combine the recombinant HVT vector vaccine with SB1 or Ris ...

Regarding recombinant vector CIAV vaccine construction rHVT to be used as a hatchery vaccination , no success yet, inserts expression cassettes VPs , no in vivo expression.Investigation using the CRISPR/Cas9 tool may be a possible solution to generate in the future rHVT/CIAV.

Based on comment of burning feathers to reduce spread of MDV may be of any help but in addition the chicken "dander "(chicken dust) epidermal scales frm skin material and feather follicles showed to be a very important factor in the spread/transmission of MDV . The MDV is very stable over long period of time in chicken dander. Re question of broiler vaccination : in US basically all broilers are ...

Several of the possible causes of the MDV failures have been put forward.I would like to add some comments re possible failures. In several cases the Marek's disease vaccines are simulteneously applied with other vaccines ,one has to make sure that these vaccines do not interfer with the MD vaccine (only use these vaccines as recommended by the vaccine manufactory),in addition in most ca ...

Over the last decennia different recombinant viral vector vaccines for poultry have been introduced in several countries.
The first vaccines were all based on the Fowl pox(FP) virus used as the vector (e.g. the avian influenza (AI) recombinant (r) FP/H5, NewcastleDisease (ND) rFP/ND, infectiouslaryngotrachetis (ILT) rFP/ILT vaccines. The most recent ("second generation") viral vect ...
