GMTs of neutralizing antibodies will be measured by microneutralization test 50% \[MNT50\] for each of the 4 Dengue Serotypes. The 4 dengue virus serotypes are DENV-1, DENV-2, DENV-3 and DENV-4. GMTs of neutralizing antibodies (by MNT) against each of the 4 dengue serotypes at Day 120 in the TDV (new) and TDV (current) groups will be reported.
