The invention provides virus-based expression vectors comprising immune-checkpoint inhibitor inserts for use as effective adjuvants in enhancing T-cell priming to an antigen in a host during a vaccination regimen. In particular, the compositions described herein are novel recombinant modified vaccinia Ankara (MVA) viral constructs encoding one or more peptides which, upon administration, are expressed in a multimer conformation and subsequently cleaved and secreted from the cell. Such peptides are capable of downregulating an immune checkpoint pathway, for example, by inhibiting the activation of programmed-cell death protein 1 (PD-1), programed cell death ligand 1 (PD-L1), cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), or another immune checkpoint regulator, or a combination thereof. When used in concert with the administration of an antigen during a vaccination strategy, the immune checkpoint expressing MVA viral construct provides significantly improved antigen-specific CD8+ T cell expansion, increased antigenic responses, and improved vaccination efficacy.

Compositions and methods are provided for reducing viral reservoirs. Stimulating viral reservoirs under conditions that reduce or clear active virus out of the body provides a two-step approach for flushing and eradicating viral reservoirs. Administration of a shock agent such as an anti-viral DNA vaccine reactivates viral reservoirs and a kill agent, such as an anti-viral vaccine or anti-viral antibody, recognizes and kills reactivated cells in the presence of systemic antiretroviral drugs to reduce or prevent infection of uninfected cells. A multiple administration regime provides repeated stimulation and flushing of viral reservoirs for effective treatment.
The present invention is directed to methods of HIV immunization, as well as methods improving an immune response to an HIV antigen(s).
