Identification of putative unique immunogenic ZIKV and DENV1-4 peptides for diagnostic cellular based tests

Abstract Since the re-emergence of Zika virus in 2014 and subsequent association with microcephaly, much work has focused on the development of a vaccine to halt its spread throughout the world. The mosquito vector that transmits this virus is widespread and responsible for the spread of other arbov...
