A radical new approach to vaccination seems to completely protect monkeys from HIV
This technique uses gene therapy to introduce a new section of DNA inside healthy muscle cells.
That strip of DNA contains the instructions for manufacturing the tools to neutralise HIV, which are then constantly pumped out into the bloodstream.
Experiments, reported in the journal Nature, showed the monkeys were protected from all types of HIV for at least 34 weeks.
As there was also protection against very high doses, equivalent to the amount of new virus that would be produced in a chronically infected patient, the researchers believe the approach may be useful in people who already have HIV.
