First New HIV Vaccine Efficacy Study Begins

Published

The first HIV vaccine efficacy study to launch anywhere in seven years is now testing whether an experimental vaccine regimen safely prevents HIV infection among South African adults.

The study, called HVTN 702, involves a new version of the only HIV vaccine candidate ever shown to provide some protection against the virus.

HVTN 702 aims to enrol 5,400 men and women, making it the largest and most advanced HIV vaccine clinical trial to take place in South Africa, where more than 1,000 people become infected with HIV every day.

“If deployed alongside our current armoury of proven HIV prevention tools, a safe and effective vaccine could be the final nail in the coffin for HIV,” said Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health and a co-founder of the trial.

“Even a moderately effective vaccine would significantly decrease the burden of HIV disease over time in countries and populations with high rates of HIV infection, such as South Africa.”

The experimental vaccine regimen being tested in HVTN 702 is based on the one investigated in the RV144 clinical trial in Thailand led by the US Military HIV Research Program and the Thai Ministry of Health.

The Thai trial delivered landmark results in 2009 when it found for the first time that a vaccine could prevent HIV infection, albeit modestly.

The new regimen aims to provide greater and more sustained protection than the RV144 regimen and has been adapted to the HIV subtype that predominates in southern Africa, a region that includes the country of South Africa.

“The people of South Africa are making history by conducting and participating in the first HIV vaccine efficacy study to build on the results of the Thai trial,” said HVTN 702 Protocol Chair Glenda Gray, M.B.B.C.H., F.C.Paed. (SA). “HIV has taken a devastating toll in South Africa, but now we begin a scientific exploration that could hold great promise for our country. If an HIV vaccine were found to work in South Africa, it could dramatically alter the course of the pandemic.” Dr Gray is president and chief executive officer of the South African Medical Research Council; research professor of paediatrics at the University of the Witwatersrand, Johannesburg; and a founding director of the Perinatal HIV Research Unit at Chris Hani Baragwanath Hospital in Soweto, South Africa.

Co-chairing the protocol with Dr. Gray are Linda-Gail Bekker, M.D., Ph.D.; Fatima Laher, M.D.; and Mookho Malahleha, M.B.Ch.B., M.P.H. Dr. Bekker is deputy director of the Desmond Tutu HIV Centre at the University of Cape Town and chief operating officer of the Desmond Tutu HIV Foundation in Cape Town, South Africa. Dr. Laher is a director of the Perinatal HIV Research Unit at Chris Hani Baragwanath Hospital. Dr. Malahleha is deputy director of Setshaba Research Centre in Soshanguve, South Africa.

The experimental vaccine regimen tested in the Thai trial was found to be 31.2 percent effective at preventing HIV infection over the 3.5-year follow-up after vaccination. In the HVTN 702 study, the design, schedule and components of the RV144 vaccine regimen have been modified in an attempt to increase the magnitude and duration of vaccine-elicited protective immune responses.

As the regulatory sponsor of HVTN 702, NIAID is responsible for all operational aspects of this pivotal Phase 2b/3 trial, which is enrolling HIV-uninfected, sexually active men and women aged 18 to 35 years. The NIAID-funded HIV Vaccine Trials Network (HVTN) is conducting the trial at 15 sites across South Africa. Results are expected in late 2020.

HVTN 702 begins just months after interim results were reported for HVTN 100, its predecessor clinical trial, which found that the new vaccine regimen was safe for the 252 study participants and induced comparable immune responses to those reported in RV144.

HVTN 100 and HVTN 702 are part of a larger HIV vaccine research endeavour led by the Pox-Protein Public-Private Partnership, or P5—a diverse group of public and private organizations committed to building on the success of the RV144 trial. The P5 aims to produce an HIV vaccine that could have a significant public health benefit in southern Africa and to advance scientists’ understanding of the immune responses associated with preventing HIV infection. P5 members include NIAID, the Bill & Melinda Gates Foundation, the South African Medical Research Council, HVTN, Sanofi Pasteur, GSK and the U.S. Military HIV Research Program.

The HVTN 702 vaccine regimen consists of two experimental vaccines: a canarypox vector-based vaccine called ALVAC-HIV and a two-component gp120 protein subunit vaccine with an adjuvant to enhance the body’s immune response to the vaccine. The vaccines do not contain HIV and therefore do not pose any danger of HIV infection to study participants. Both ALVAC-HIV (supplied by Sanofi Pasteur) and the protein vaccine (supplied by GSK) have been modified from the versions used in RV144 to be specific to HIV subtype C, the predominant HIV subtype in southern Africa. Additionally, the protein subunit vaccine in HVTN 702 is combined with MF59 (also supplied by GSK), a different adjuvant than the one used in RV144, in the hope of generating a more robust immune response. Finally, the HVTN 702 vaccine regimen includes booster shots at the one-year mark in an effort to prolong the early protective effect observed in RV144.

The study volunteers are being randomly assigned to receive either the investigational vaccine regimen or a placebo. All study participants will receive a total of five injections over one year.

The safety of HVTN 702 study participants will be closely monitored throughout the trial, and participants will be offered the standard of care for preventing HIV infection. Study participants who become infected with HIV in the community will be referred to local medical providers for care and treatment and will be counselled on how to reduce their risk of transmitting the virus.

HVTN 702 is one of many NIAID-supported HIV prevention trials in progress in southern Africa. These include the AMP Studies, which are testing infusions of the VRC01 antibody; the open-label HOPE study, which is examining a dapivirine vaginal ring; and HPTN 076 and 077, which are studying long-acting injectable rilpivirine and cabotegravir, respectively.

resident doctors strike

By Adedapo Adesanya

The Nigerian Association of Resident Doctors (NARD) has suspended its planned nationwide indefinite strike, granting the federal government a two-week ultimatum to address lingering welfare issues affecting resident doctors across the country.

The decision was taken after an emergency meeting of the association’s National Executive Council on Tuesday, where members reviewed assurances from government representatives and resolved to give dialogue another chance.

NARD said the suspension was informed by “progress made” in negotiations, particularly commitments on the prompt payment of salary arrears, hazard allowances, and steps toward resolving issues surrounding the Medical Residency Training Fund.

The association did not declare a full resolution of the dispute. It noted that the government had shown “renewed willingness” to address the concerns that triggered the strike threat.

The association noted that while these engagements signalled a willingness by the government to resolve the dispute, several critical issues remain outstanding, particularly the delayed payment of promotion arrears, salary arrears, the 2026 Medical Residency Training Fund (MRTF), and the backlog of 19 months’ professional allowance arrears owed to resident doctors.

It also expressed concern over the Federal Government’s decision to halt the implementation of the reviewed PAT, which had earlier triggered widespread dissatisfaction among its members and raised fears of disruption to healthcare services nationwide.

Despite these unresolved issues, NARD said it opted to suspend the strike as a demonstration of goodwill and commitment to ongoing dialogue, while giving the government a two-week window to take concrete, measurable and verifiable steps to meet its demands.

The association insisted on the immediate reversal of the decision affecting the PAT, payment of all outstanding arrears, prompt disbursement of the MRTF, and full settlement of the accumulated professional allowance backlog.

It warned that it would reconvene at the expiration of the ultimatum to assess the level of compliance and determine its next course of action, adding that failure by the government to meet its demands within the stipulated timeframe would result in the resumption of the suspended strike without further notice.

NARD also called on its members nationwide to remain calm, united and resolute, while urging the Federal Government to act swiftly to prevent a potential crisis in the health sector.

The association further appreciated the interventions of the Vice President and other stakeholders, expressing hope that their involvement would lead to the timely resolution of the dispute and help sustain healthcare delivery across the country.

Jacaranda Maternity

By Modupe Gbadeyanka

To expand affordable healthcare in Kenya, Swedfund has invested about $600,000 into Jacaranda Health Limited (Jacaranda Maternity) to support innovations in neonatal intensive care and strengthen Jacaranda’s ability to provide life-saving services to underserved populations.

Jacaranda Maternity provides high-quality maternal health care at more affordable pricing than typical private providers, focusing on women in Nairobi’s low- and middle-income communities.

The new funding will support the opening of new hospitals, upgrading of neonatal care, and improvements to existing facilities.

Maternal and newborn health outcomes in Kenya remain a challenge, with maternal mortality still high despite improvements in skilled birth attendance.

Public health facilities play a central role but face capacity constraints, while access to reliable, quality care varies across regions and income groups.

Private healthcare providers offering essential maternity services at accessible price points can complement public provision.

Jacaranda Maternity aims to expand its network to six hospitals to achieve financial sustainability while scaling its impact. The healthcare provider is a recognised leader in promoting women’s health, with 71 percent of its staff being women, and a track record of effective environmental and social management.

“This investment will help Jacaranda Maternity provide life-saving care to more women and families while furthering Swedfund’s mission to promote inclusive and sustainable healthcare,” a Senior Investment Manager at Swedfund, Audrey Obara, said.

Nigeria will get a $350,000 intervention from the Food and Agriculture Organisation of the United Nations (FAO) to support its response to the ongoing outbreak of Highly Pathogenic Avian Influenza (bird flu) and strengthen the country’s animal health systems.

An agreement was reached on Wednesday during a strategic meeting between the Minister of Livestock Development, Mr Idi Mukhtar Maiha, and the FAO Representative to Nigeria and the Economic Community of West African States, Mr Hussein Gadain, in Abuja.

The intervention, approved under FAO’s Technical Cooperation Programme, will support disease containment efforts in 11 affected states and enhance surveillance, coordination and response mechanisms to prevent further spread of the disease.

Speaking during the meeting, Maiha said effective disease control remains critical to improving livestock productivity and protecting the livelihoods of farmers across the country.

He explained that factors such as drought, scarcity of feed, interaction between livestock and wildlife, as well as cross-border movement of animals have contributed to the spread of diseases in some areas.

“We must continue to strengthen our animal health systems and build the capacity required to respond effectively to disease outbreaks. Our collaboration with FAO will help protect livestock assets, improve productivity and support the broader transformation of the sector,” the minister said.

Mr Gadain commended the federal government’s commitment to the development of the livestock sector and assured that FAO would continue to provide technical support to Nigeria.

He stressed the need to strengthen veterinary services at the state and community levels, improve early detection of diseases and promote biosecurity practices among livestock farmers.

The meeting also reviewed progress on the global campaign to eradicate Peste des Petits Ruminants, a highly contagious disease that affects sheep and goats.

To advance the initiative, the ministry plans to convene a national technical meeting involving veterinary institutions, researchers and practitioners to review Nigeria’s eradication strategy and address gaps in vaccine supply.

As part of preparations, the ministry will engage the National Veterinary Research Institute to assess its vaccine production capacity while exploring other options for vaccine procurement to meet national demand.

Both parties also agreed to accelerate Nigeria’s access to financing under the Pandemic Fund through the One Health approach in collaboration with the Nigeria Centre for Disease Control and the Federal Ministry of Health to strengthen preparedness and response to zoonotic diseases.

Plans are also underway for the Director-General of FAO to participate in the Antimicrobial Resistance Conference scheduled for June 2026 in Abuja, where President Bola Tinubu is expected to be recognised as the African Champion for the eradication of Peste des Petits Ruminants.

The meeting further agreed to inaugurate a Livestock Donor Working Group to coordinate development partner support and advance key initiatives, including the development of a national feed and fodder strategy aimed at improving productivity and sustainability in the livestock sector.
