What is this study about?

EHVA P01 / ANRS VRI08 is a phase I, prophylactic HIV vaccine trial to evaluate the safety and immunogenicity of HIV Clade C DREP alone and in combination with a Clade C ENV protein in healthy HIV-uninfected adults. 

The study is looking at the use of a new vaccine against the HIV virus. There are two parts to the study:

  • The first part is open-label and will assess the safety of this vaccine, since this will be the first time that it has been used in humans.
  • The second part aims to see how well and for how long the vaccine activates the immune system.

This trial is not looking at whether or not the vaccine is effective in terms of protecting against HIV, it is just assessing whether and how well the immune system responds.
