Zika Vaccines Protect Mouse Fetuses

July 13, 2017

(The Scientist) – Pregnant women and their children bear the destructive brunt of Zika, and since appreciating the connection between prenatal viral infection and the irreparable fetal harm associated with Congenital Zika Syndrome, independent groups of scientists are taking initial steps toward protecting those most vulnerable. In a first-of-its-kind study published today (July 13) in Cell, researchers demonstrated that in mice, either of two vaccines—a live attenuated virus and a non-replicating, modified mRNA vaccine—can impede Zika transmission from mother to baby in utero. These data come two weeks after a multi-disciplinary collaborative of bioethicists, physicians, and immunologists published a set of guidelines outlining how to conscientiously incorporate pregnant women into Zika vaccine trials.
