Abstract

ABSTRACT Immunoglobulin G reactive with primary isolate virions was detected in 36% of serum samples from individuals infected with human immunodeficiency virus type 1. Of these individuals, serum samples from only 7% captured significant quantities of virus. Virion-specific antibody correlated with CD4 counts and, of more significance, primary isolate neutralization. Further dissection of this response should lead to the identification of antibodies and antigenic epitopes for vaccine purposes.
