*DENV, dengue virus; PRNT90, plaque reduction neutralization test with neutralization defined as >90% reduction in challenge virus PFUs. †Serum samples that neutralized >90% of the challenge virus at a 1:10 dilution on initial Zika virus PRNT90 screening. ‡Serum samples that neutralized Zika virus only or had a PRNT90 titer >4-fold higher for Zika virus than for any DENV. §Serum samples that neutralized Zika virus and DENV and had a PRNT90 titer for Zika virus that was <4-fold higher than that for any DENV.
