Individual LNI titers are presented in the same order as for Table 1. a Neutralizing titer expressed as the logarithmic neutralization index (LNI), where samples coming from MVvac2 and MVvac2(HBsAg)N immune animals (eight samples) set the zero for neutralization of DV2 infectivity (see text); b PRNT₅₀ obtained in pooled serum samples for each experimental group, all of tested pre-immune samples lacked reactivity against DV2, PRNT < 1:10, LNI ~ 0.
