Specifically, persons with psychotic disorders, major affective disorders, suicidal ideation are to be excluded;~* Current use of psychotropic drugs prescribed for major psychotic disorders;~* Concomitant participation in any experimental study;~* Current or prior therapy with immunomodulators or immunosuppressive drugs and anticoagulant drugs within 30 days prior to study medication administration;~* Live attenuated vaccines within 60 days of study inclusion \[NOTE: Medically indicated sub-unit or killed vaccines (e.g., influenza, pneumococcal, hepatitis A and B) are not exclusionary, but should be given at least 4 weeks away from HIV immunizations\];~* Receipt of blood products or immunoglobulin in the past year;~* Previous participation in an HIV-1 vaccine trial (subjects who despite their participation as placebo in a HIV-1 vaccine trial have never been effectively administered with a HIV-1 vaccine are eligible);~* Drug and/or alcohol abuse;~* Use in the last 6 months or concomitant use of anti CCR5 inhibitors and/or integrase inhibitors and/or fusion inhibitors;~* Pregnant or lactating women
