3.   But efforts to develop a genetically engineered AIDS vaccine from parts of HIV have failed to bear out initial enthusiasm.

4.   Hope is now centered on a new vaccine strategy, a combination of two genetically engineered vaccines, that is headed for second-stage testing.

6.   Masters has agreed to be inoculated seven times over the next three years with a genetically engineered vaccine, known as Aidsvax, to find out whether it works.

7.   The combination strategy uses two genetically engineered vaccines.

8.   The latest effort involves a genetically engineered vaccine from the bark of the South American soap bark tree, Chinese hampster ovaries and a bacteria called S. minnesota.
