				Abstract 
 
              Aim: 
              To develop a mucosal inactivated 
              vaccines for Newcastle disease (ND) and H9N2 viruses to protect 
              against these viruses at sites of infections through mucosal 
              immunity. 
              Materials and Methods: 
              In this study, we prepared two 
              new formulations for mucosal bivalent inactivated vaccine 
              formulations for Newcastle and Avian Influenza (H9N2) based on the 
              use of nanoparticles and polymer adjuvants. The prepared vaccines 
              were delivered via intranasal and spray routes of administration 
              in specific pathogen-free chickens. Cell-mediated and humoral 
              immune response was measured as well as challenge trial was 
              carried out. In addition, ISA71 water in oil was also evaluated. 
              Results: 
              Our results showed that the use of 
              spray route as vaccination delivery method of polymer and 
              nanoparticles MontanideTM adjuvants revealed that it enhanced the 
              cell mediated immune response as indicated by phagocytic activity, 
              gamma interferon and interleukin 6 responses and induced 
              protection against challenge with Newcastle and Avian Influenza 
              (H9N2) viruses. 
              Conclusion: 
              The results of this study 
              demonstrate the potentiality of polymer compared to nanoparticles 
              adjuvantes when used via spray route. Mass application of such 
              vaccines will add value to improve the vaccination strategies 
              against ND virus and Avian influenza viruses.
