The Zika virus candidate, Ad26.ZIKV.001, a replication-incompetent human adenovirus serotype 26 (ad26) vector showed promising safety and immunogenicity in a phase I clinical trial. Researchers say the vaccine warrants further development should the need reemerge. The findings are published in Annals of Internal Medicine.
Zika virus (ZIKV) infection is transmitted via mosquito or sexually and may cause severe congenital disease after maternal-fetal transmission. The incidence of Zika virus has declined since the 2015-2016 outbreak, but geographic expansion of the Aedes aegypti mosquito to areas where population-level immunity is low poses a substantial risk for future epidemics. Currently, no vaccine is available.
