§ Mr. Alfred MorrisTo ask the Secretary of State for Health what information is available to him on the effectiveness of anti-viral drugs in preventing or delaying the development of AIDS in people who are HIV positive; and if he will make a statement.
§ Mr. Mellor[holding answer 25 January 1989]No anti-viral drug to prevent or delay the development of AIDS in people who are HIV positive has yet reached a stage at which it is licensed for general use. The most advanced is Zidovudine which is currently undergoing clinical trials to assess its efficacy for this purpose.
