WASHINGTON — Testing in humans of an HIV vaccine that uses messenger RNA technology has begun, the biotech firm Moderna and the International AIDS Vaccine Initiative said Thursday (Jan 27).

This Phase 1 trial is being carried out in the United States among 56 healthy adults who are HIV negative.

The vaccine is supposed to teach B lymphocytes, which are part of the immune system, to generate these antibodies. "Further immunogens will be needed to guide the immune system on this path, but this prime-boost combination could be the first key element of an eventual HIV immunization regimen," said Dr David Diemert, a lead investigator at one of the four sites where the trial is being carried out, George Washington University in the US capital.
