Ans. D
of the vaccination procedures listed, the FDA is most likely to test the procedure that uses a human monoclonal antibodies that react with intact CD4 (T4) recpetor. Antibodies that react with CD4 should look like the portion of HIV that reacts with CD4 receptors. therefore, the vaccinated person should make an antibody to the human monoclonal antibody, which may protect against HIV.
