A DNA/rMVA vaccine strategy is structured to bring about both T cell and antibody responses. The primary vaccination is DNA based and will express only HIV proteins as a way to produce an HIV-focused immune response. A secondary, rMVA boost vaccination, which expresses both HIV and MVA proteins will ideally amplify the focused response of the initial vaccination. The DNA and rMVA are physically two different vaccinations given at separate times but together they make up one preventive regimen. Both vaccine components express non-infectious virus-like particles.
