Vaccine trial results generate debate and calls for further research

The first large-scale human trial of an HIV vaccine produces disappointing results overall, but finds that the vaccine may have been effective among some of the minority populations participating in the trial. Whatever the significance of this finding (the debate continues), there was a consensus: (a) that the trial provided very useful information on how to conduct large-scale HIV vaccine trials; (b) that further research needs to be conducted; (c) that governments need to contribute more to vaccine research and development; and (d) that existing prevention efforts must be maintained or expanded.
