Researches have reported a breakthrough in the search for a treatment for Zika virus. To better understand this report, you will need to know the following words: antibody, vaccine and immune system. Researchers have discovered an antibody that greatly reduces infection with Zika. This antibody could possibly be made into a vaccine to protect people against the virus. Researchers named the antibody ZIKV-117. An antibody is an immune system protein. Researchers got the antibody from a Zika patient. Then they tested the antibody in pregnant mice infected with Zika. ZIKV-117 protected the fetus against infection. The antibody creates a strong reaction to the virus in the immune system. In fact, ZIKV-117 neutralized, or made harmless, each kind of Zika that the scientists tested. The antibody also greatly decreased the amount of virus in the pregnant mice. And, the researchers found decreased levels of the virus in fetal tissue, including brain tissue.
