Thanks all of you for this good article.I'd like to ask about the study that you mentioned about use of HVT vector vaccine expressing HA to protect against multiple lineages of HPAI; Did you have challenged birds with different types of AI like H9 or H7? And what's the explanation for this protection?

Thank you both (Dr. Bakri/Dr. Belwal) for sharing your views.
