Table 2.

Neutralization Response Demonstrated by Seroconverters^a

	Neutralization response against
Categorization of seroconverters (n = 33)	Isolate C-I	Isolate C-II	Neutralization response against isolates C-I and C-II
Responders	7 (21%)^b	9 (27%)	7 (21%)^c
Nonresponders	26 (79%)	24 (73%)	26 (79%)

^{^a}

This table shows % neutralization response demonstrated individually against isolates C-I and C-II (column 2) as well as the mean % neutralization against both isolates (column 3). The neutralization > 50% was considered as positive neutralization. Seroconverters showing < 50% neutralization and those demonstrating inconsistent positive neutralization responses between the two visits were considered as nonresponders. Seroconverters showing positive neutralization on all visits were classified as responders.

^{^b}

Number (%).

^{^c}

Of the seven responders showing neutralization against both isolates, four were early responders (responses observed within 6 months postinfection) and three were late responders (responses observed > 6 months postinfection).
