Abstract
Over the past decade, chikungunya virus (CHIKV)has emerged as a major cause of mosquito-borne disease with transmission reported in over 100 countries worldwide. Although several strategies have been pursued for the development of a CHIKV vaccine, none has been approved yet. In this study, we describe the development of several vaccine vectors that express the structural proteins of the La Réunion CHIKV strain LR2006-OPY1. Protection from virus-induced pathologic changes was observed in vaccinated C57BL/6 mice, an important model for CHIKV vaccine development because of their ability to recapitulate several signs shown in infected humans. This study uniquely demonstrates the capacity of a mucosally-administered adenovirus vaccine to induce serum antibody responses and confer protective efficacy in a pre-clinical model. Our data provide further evidence in support of the clinical development of this oral Ad-CHIKV vaccine strategy in populations at high risk of contracting the disease.
