HIV-1 Multi-Clade, Multivalent Recombinant Vaccine Construct

CDC scientists developed immunogenic multi-clade, multivalent (HIV1MCMV) recombinant constructs for use as HIV-1 vaccines. These polypeptides include immunogenic CTL, T- and/or B-cell determinants that are capable of eliciting broad and effective immune responses against diverse subtypes of HIV-1. It is believed that these HIV-1 constructs provide universal vaccines, capable of effective use in any part of the world affected by the HIV-1 epidemic. The construct contains specific cellular targeting epitopes that allow optimized antigen processing and recognition, and the design of the construct allows for the addition or deletion of epitopes. Additionally, the construct may be used to develop multi-pathogen vaccines by combination with other epitope-based constructs.
