Immunogenicity of a DNA vaccine against herpes B virus in mice and rhesus macaques.
Herpes B virus (Cercopithecine herpesvirus 1) is endemic in captive macaque populations and poses a serious threat to humans who work with macaques or their tissues. A vaccine that could prevent or limit B virus infection in macaques would lessen occupational risk. To that end, a DNA vaccine plasmid expressing the B virus glycoprotein B (gB) was constructed and tested for immunogenicity in mice and macaques. Intramuscular (IM) or intradermal (ID) immunization in mice elicited antibodies to gB that were relatively stable over time and predominately of the IgG2a isotype. Five juvenile macaques were immunized by either IM+ID (n=2) or IM (n=3) routes, with two booster immunizations at 10 and 30 weeks. All five animals developed antibodies to B virus gB, with detectable neutralizing activity in the IM+ID immunized animals. These results demonstrated that DNA immunization can be used to generate an immune response against a B virus glycoprotein in uninfected macaques.
