In this preclinical study, 100 percent of the animal models were protected from Zika after vaccination followed by a challenge with the Zika virus. In addition, they were protected from degeneration in the cerebral cortex and hippocampal areas of the brain, while the other cohort showed degeneration of the brain after Zika infection.
“Our results support the critical importance of immune responses for both preventing infection as well as ameliorating disease caused by the Zika virus,” said lead researcher David B. Weiner, Ph.D., Executive Vice President and Director of the Vaccine Center at The Wistar Institute and the W.W. Smith Charitable Trust Professor in Cancer Research at Wistar. “As the threat of Zika continues, these results provide insight into a new aspect of the possibly protective ability of such a vaccine as a preventative approach for Zika infection.”
This study is the first of its kind to analyze a vaccine in an
