The proportion of volunteers who develop a grade 3 or 4 local reaction
Grade 3 or 4 systemic reaction [ Time Frame: Up to 24 weeks ] [ Designated as safety issue: Yes ]
The proportion of volunteers who develop a grade 3 or 4 systemic reaction
Serious adverse event, including laboratory abnormalities. [ Time Frame: Up to 24 weeks ] [ Designated as safety issue: Yes ]
The proportion of volunteers who develop a serious adverse event, including laboratory abnormalities.

Secondary Outcome Measures:

HIV-specific CD8+ T cell responses [ Time Frame: Change from baseline (pre-HAART) and w24, to +1week, +4weeks, +12weeks and +24weeks post vaccination. ] [ Designated as safety issue: No ]
The proportion of individuals who increase by ≥ 3-fold HIV-specific CD8+ T cell responses. Responses to the HIVconsv and outside the vaccine insert will be assessed.
Magnitude and phenotype of HIV-1-specific CD8+ T cell populations [ Time Frame: Change from baseline (pre-HAART) and w24, to +1week, +4weeks, +12weeks and +24weeks post vaccination. ] [ Designated as safety issue: No ]
Magnitude and phenotype of HIV-1-specific CD8+ T cell populations , in selected volunteers with appropriate HLA class I alleles will be assessed according to first immunogenicity results.
Lymphocyte activation marker HLADR+CD38+ [ Time Frame: Change from baseline (pre-HAART) and w24, to +1week, +4weeks, +12weeks and +24weeks post vaccination. ] [ Designated as safety issue: No ]
Lymphocyte activation marker HLADR+CD38+ will be assessed at selected timepoints according to first immunogenicity results
Integrated and unintegrated viral HIV-1 DNA in PBMCs. [ Time Frame: Change from baseline (pre-HAART) and w24, to +1week, +4weeks, +12weeks and +24weeks post vaccination. ] [ Designated as safety issue: No ]
Quantification of integrated and unintegrated viral HIV-1 DNA in PBMCs will be determined at selected timepoints according to first immunogenicity results
Viral suppressive capacity of CD8+ T cells in vitro [ Time Frame: Change from baseline (pre-HAART) and w24, to +1week, +4weeks, +12weeks and +24weeks post vaccination. ] [ Designated as safety issue: No ]
Viral suppressive capacity of CD8+ T cells in vitro using a flow cytometric assay at selected timepoints according to first immunogenicity results

Experimental: 0-24 week prime/boost regimen (ARM A) ChAdV63.HIVcons and MVA.HIVconsv HIV-1 vaccines, delivered intramuscularly, 0-24 week prime/boost regimen	Biological: 0-24 week prime/boost regimen ChAdV63.HIVcons (5x10^10 vp) and MVA.HIVconsv (2x10^8 pfu) HIV-1 vaccines, delivered intramuscularly Other Name: ARM A
Experimental: 0-8 week prime/boost regimen (ARM B) ChAdV63.HIVcons and MVA.HIVconsv HIV-1 vaccines, delivered intramuscularly, 0-8 week prime/boost regimen	Biological: 0-8 week prime/boost regimen ChAdV63.HIVcons (5x10^10 vp) and MVA.HIVconsv (2x10^8 pfu) HIV-1 vaccines, delivered intramuscularly Other Name: ARM B

Detailed Description:

It is a Phase I, multicenter primary/booster therapeutic vaccination study to evaluate the safety and immunogenicity of ChAdV63.HIVcons and MVA.HIVconsv HIV-1 vaccines, delivered intramuscularly according to a 0-8 weeks or a 0-24 weeks schedule to recently HIV-1 infected individuals with early viral suppression 6 months after initiation of Tenofovir/Emtricitabine plus Raltegravir.

24 patients who meet all eligibility criteria will be enrolled, first 10 individuals will be assigned in the 0-24 week prime/boost regimen (ARM A). The next 10 volunteers will be assigned in the 0-8 week prime/boost regimen (ARM B).Four additional volunteers will be included as 'back-up' and assigned 2 in ARM A and 2 in ARM B to cover a possible 10% of patients who drop-off during the follow-up. Purpose of staging of 2 study arms is just to shorten overall study duration (from screening of first volunteer to 6 months after last immunisation of last volunteer).

Eligibility

Ages Eligible for Study:	18 Years to 60 Years
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No
