^aPublic animal identifiers (PAI) are used in studies on the Zika Open Research Portal (https://zika.labkey.com/project/OConnor/begin.view?). All animals were female. Animal C1 was previously infected with 10⁴ PFU of ZIKV-MR766 and rechallenged with 10⁴ PFU of ZIKV-FP 70 days after initial ZIKV infection (45). Animal C2 was previously infected with 10⁶ PFU ZIKV-FP and Dengue virus 3 164 days prior to initial ZIKV infection (47). Animals C5 and C3 were previously infected with 10⁴ PFU of ZIKV-FP during their first and late second/early third trimesters of pregnancy, respectively (46). Animal C4 was previously infected with 10⁶ PFU of ZIKV-FP and rechallenged 70 days after initial infection with10⁴ PFU of ZIKV-FP (44). All animals were rechallenged with 10⁴ PFU of ZIKV-PR 675 to 858 days after initial infection.

^bThe pregnancy status at the time of initial infection: NP, nonpregnant; P, pregnant.
