Recombinant proteins viral vaccine development

Despite these theoretical concerns, a number of HIV vaccines are under development. Most of these vaccines have been developed by recombinant DNA techniques that have allowed a large-scale production of individual viral proteins. The predominant HIV proteins that make up these potential vaccines are env proteins (e.g., gp 120) and, to a lesser extent, gag proteins. In addition, inactivated whole HIV virus is being tested.
