Abstract

Events in the pathogenesis of infection and the host response to VZV are very closely linked. Our experiments demonstrate that CD4- and CD8+ T-lymphocyte populations that are targets of cell-associated VZV viremia also mediate protection against severe infection. Diminished cell-mediated immunity predisposes the host to progressive primary or recurrent VZV disease because infected lymphocytes persist in the circulation and carry the virus to major organs, causing pneumonitis, hepatitis, or other life-threatening complications. The live attenuated varicella vaccine induces cell-mediated immunity and protects against or significantly reduces the morbidity associated with primary VZV infections. The universal administration of varicella vaccine is likely to generate new insights about host-virus interactions, particularly in relation to how VZV immunity is maintained, that will be relevant to the design of vaccines for other human herpesviruses.
