Zika virus is a mosquito borne virus that causes Guillain-Barré syndrome, microcephaly and death in congenitally exposed fetuses. SAB Biotherapeutics has developed a transchromosomic bovine platform that produces large quantities of fully-human polyclonal antibodies (SAB-155) which is highly effective in treating ZIKV infection, both prophylactically and therapeutically. In this study levels of infection on non-treated and treated hamsters with the SAB-155 antibody where quantified by performing a RT-PCR on the MIC, where protection was conferred even 4.5 days post infection of the Zika virus.
