The first study to test this new technology that started with COVID-19 vaccines will have sites in Rwanda and South Africa which are building on recent findings from a similar trial conducted among healthy adults in the US where researchers found vaccination induced the targeted immune responses in 97% of recipients.
global scientific research organization IAVI announced on Wednesday that they are
set to start screening participants into a Phase I Clinical trial in which they
are testing effectiveness of an mRNA vaccine in preventing HIV.
study to test this new technology that started with COVID-19 vaccines will have
sites in Rwanda and South Africa which are building on recent findings from a
similar trial conducted among healthy adults in the US where researchers found
vaccination induced the targeted immune responses in 97 per cent of recipients.
study dubbed IAVI G003 will involve 18 healthy, HIV-negative adult volunteers
who will receive two doses of the vaccine, which contains a portion of the
viral sequence and cannot cause an infection with HIV.
a statement released on Wednesday, there is no blinding and no randomization in
this open-label study and that all participants will receive the intervention.
is designed to test the hypothesis that vaccination... developed
by scientific teams at IAVI and delivered via Moderna’s mRNA platform can
induce similar immune responses in African populations as was seen for IAVI
G001 in the US”, reads the statement in part.
remarks, IAVI CEO Mark Feinberg said while the road to an HIV vaccine has been long and
winding with the search starting more than 30 years ago, mRNA technology has
the potential to accelerate the development of a safe, effective, affordable,
and durable HIV vaccine for use throughout the world.
this announcement that collides with the World HIV Vaccine Awareness day marked
every 18th of May, Linda – Gail Bekker, an HIV activist and Professor
of Medicine said this renews their hope for a vaccine after a hitherto promising Phase 2b trial known as Imbokodo
was discontinued last year when people in the study got infected.
She said the
pipeline is rich with five mRNA vaccine candidates now being tested across the
world. In addition to these, there’s a PrEPVACC ongoing in East and Southern
Africa testing an experimental vaccine and Pre-Exposure Prophylaxis at the same

On her part,
Maureen Luba, a Programs Officer at the Global Advocacy for HIV Prevention
(AVAC) said even with other HIV prevention innovations recently found, the
vaccine remains an important public health intervention and this new technology
marks a new research age.

key important lessons.”//
participants in the new study will be monitored for safety for six months after
receipt of the last dose, and their immune responses will be examined in
molecular detail to evaluate whether the targeted responses will be achieved.
trial endpoints are safety and immunogenicity, defined as the ability of a substance
to elicit an immune response.
