No vaccine or therapy currently exists for Zika, a mosquito-borne illness that can cause fevers and rashes in infected people. It rarely requires hospitalization, although scientists have found links between the virus and a pair of serious and rare conditions.
Pregnant women who have Zika can give birth to babies suffering from microcephaly, a birth defect that gives newborns smaller than average heads. It can also cause Guillain-Barré syndrome, a rare condition that causes temporary weakness and sometimes paralysis.
The disease can also be sexually transmitted.
At least six pregnant women in the U.S. have reported Zika-related complications, according to numbers released last week by the Centers for Disease Control and Prevention. Of those, three lost or terminated their pregnancies because of the virus.
Of the 756 cases of Zika infection reported in the U.S., all but one was contracted abroad. The remaining infection was contracted in a laboratory, according to the CDC.
Three of those cases resulted in Guillain-Barré syndrome.
In addition to Innovo, at least 15 other companies are working to develop a Zika vaccine, according to WHO.
