Through the unique properties of Nanoparticles, it has been shown that they can be used as synthetic antigens, vaccine delivery systems, adjuvants, and immunomodulators, increasing the accuracy of targeting, cross-presentation of peptides, and improving other factors. Even without adjuvants, Nanoparticles can be functionalized to attach selectively to specific cellular receptors, triggering a strong immune response, but as adjuvants, they can slow down antigen release and increase vaccine performance. With all the emerging and already employed forms of veterinary nanovaccines which utilise nano-emulsion particles, chitosan nanoparticles and many more, they start to offer wider possibilities for administration methods, practicality and vaccine effectiveness.
