As of mid-2019, 87 countries have had or still have Zika cases, underlining the importance of this infectious disease. Zika virus can infect the uterus and later infect the infant during pregnancy, causing neurodevelopmental defects at birth. This study will model Zika infection in the lab using uterine mini-organs. We hypothesize that our specific antibodies can neutralize Zika virus in the uterus and thus prevent later transmission from pregnant mother to unborn child.
