To address this, we examined neonatal survival from 17 litters of AIR mice resulting in 100 offspring that were treated according to our standard model which includes a 104-plaque forming unit (PFU) inoculum dose of ZIKV to mice treated with 1 mg/mouse anti-IFNAR1 on -1 and 3 dpi (days post infection) and 0.5 mg/mouse on 7 and 11 dpi (Fig. 1a, AIR, red circles). This evidence concerns the gene IFNAR1 and infection.
