Circumcision can halve the risk of a man picking up the HIV infection which leads to Aids, scientists in the United States said last night.

The development of vaccines against the three most lethalinfectious conditions - HIV-AIDS, malaria and tuberculosis, which together kill seven million people each year - will rely on work involving non-human primates for the foreseeable future...
Vaccine development is particularly reliant on monkey studies, to assess candidates before they proceed to expensive human trials. Neuroscience requires primates because they are the only animals with brain circuitry remotely similar to that of humans. There is also a case for allowing primate research for investigating reproductive medicine.
Sometimes there may be a reason we started doing things.
