Zimbabwe
selected for ground-breaking HIV vaccine research
ZIMBABWE will participate in the first ever HIV
vaccine research trials conducted in four continents to establish if an
anti-body mediated prevention (AMP) can help to end HIV.
HIV and Aids continue to kill thousands of people
annually in Sub-Saharan Africa and the disease has no known cure.
A vaccine may help to eradicate the pandemic
globally through preventing new infections.
The study, researchers say, will test whether giving
people an investigational anti-HIV anti-body called VRC01 as an intravenous
infusion every 8 weeks is safe, tolerable and effective at preventing HIV
infection.
Sub-Saharan Africa remains the region most affected
by HIV with 25 million adults and children living with the disease.
Zimbabwe whose HIV prevalence rate is 14 percent, is
the fifth highest in Sub-Saharan Africa.
In an interview at the world HIV Research for
Prevention Conference in Chicago United States of America, Dr Nyaradzo Mmgodi,
the University of Zimbabwe and University of California San Francisco (UZ-UCSF)
project manager said South Africa, Tanzania, Mozambique, Malawi, Botswana and
Kenya would also participate in the research dubbed the HVTN702.
“We’ve never seen cases of polio in Zimbabwe because
we’ve an effective vaccine against it and that’s the aim with HIV. The most
effective public health intervention to deal with infectious diseases is
vaccines and we would want to bring an end to HIV,” said Dr Mmgodi.
“We’re excited about the study which is going to
take us about 15 to 20 years. In the meantime, we are promoting Prep
(Pre-exposure prophylaxis), vaginal ring and other interventions to prevent and
treat HIV.
“It’s a big study being conducted on four
continents, North and South America, Europe and Sub-Saharan Africa and will
incorporate 4 200 women across the continents and 1 500 women in the seven
African countries,” she said.
Dr Mmgodi said the anti-body concept was taken from
a group of people known as elite controllers who can manage and suppress HIV
without treatment.
“One of these elite controllers was found to have
VRCO1 like antibodies which help them control HIV without treatment. This
antibody was taken and a similar anti-body was manufactured in the lab by the
Vaccines Research Centre. Our readers must understand that this anti-body which
we will be testing didn’t come from a HIV infected. this VROC1 was manufactured
to resemble the anti-body which was found in the elite controller,” she said.”
Dr Mmgodi said during the research, the anti body
would be given as an infusion to each participant for 22 months. The
participants will get a total of 10 infusions once every eight weeks.
“They will visit the clinic monthly for examinations
so we also check for HIV and other health related conditions. This will be a
proof of concept study and we really want to prove if anti bodies can help.”
Dr Mmgodi said to date more than 500 participants in
America have used the VROC1, which has proven to be safe with no complications.
In Sub- Saharan Africa, the research has started in
South Africa and Botswana.
“We have received most of our approvals for Zimbabwe
and Kenya so we should be starting soon. The information gathered from AMP will
eventually help us bring an end to HIV so that for once after decades we can
focus on other diseases.”
At present HIV infected people are taking anti-
retroviral medication to suppress the virus. Other interventions that have been
proven so far include Prep. This is when people at very high risk for HIV take
HIV medicines daily to lower their chances of getting infected and this is yet
to be rolled out in Zimbawe.
By reducing new HIV infections, Aids vaccination
could reduce total resources needed to sustain effective prevention and
treatment programmes.
The HIV Research for Prevention 2016 is the world’s
only global scientific meeting dedicated exclusively to biomedical HIV
prevention research.
It works to promote interaction and debate among
attendees and to break down silos between prevention research specialties.
About 1 419 researchers, advocates, clinicians,
policy makers and private sector partners from 41 countries attended the
five-day conference, which ended last Friday.
