Bovine monocyte derived dendritic cell based assay for measuring vaccine immunogenicity in vitro.

During both human and animal vaccine development phases, animal testing is necessary to demonstrate vaccine efficacy. Since the number of antigen candidates for testing is usually large when developing a potential vaccine, it is too costly, time consuming and would involve higher risks to carry out selection using in vivo models. The currently available in vitro assays that measure immunogenicity do not adequately reproduce the in vivo state and this is especially true for vaccine research in livestock species.
