I welcome what the Secretary of State has just said. There is indeed a great danger that drugs could be seen as the answer to the AIDS pandemic, but they could make it worse if they are not used properly. Does the right hon. Lady agree that while education and condom use are the only real answer in the short term, a vaccine against AIDS is the only long-term solution? The international AIDS vaccine initiative needs $1 billion to further its trials and continue research, so when she goes to the United Nations in June, will she persuade other Governments and our own to increase their contributions to ensure that the vaccine becomes a reality?
