I do hope they have success. I would assume they would test it on high risk patients such as those having an intimate relationship with someone who was HIV + or living in areas with a very high incidence of the disease.

I agree the cost of the vaccine is likely to mean it will not be available to those at the greatest risk and even then in a number of African nations there are huge social, cultural and political issues to overcome to allow for vaccination to occur.

L&B I agree a vaccine for malaria would also save hundreds of lives and is really important too
