Ghana to pilot WHO – coordinated malaria vaccine programme

Ghana, Kenya, and Malawi will take part in a WHO-coordinated malaria vaccine implementation programme (MVIP) that will make the world’s first malaria vaccine available in selected areas, beginning in 2018.

The WHO Regional Office for Africa (WHO/AFRO) announced this programme on Monday, in a release made available to the Ghana News Agency.

The injectable vaccine, RTS, S, was developed to protect young children from the most deadly form of malaria caused by Plasmodium falciparum.

It said RTS,S would be assessed in the pilot programme as a complementary malaria control tool that could potentially be added to the core package of WHO- recommended measures for malaria prevention.

Dr Matshidiso Moeti, WHO Regional Director for Africa said: “The prospect of a malaria vaccine is great news.

“Information gathered in the pilot programme will help us make decisions on the wider use of this vaccine.

“Combined with existing malaria interventions, such a vaccine would have the potential to save tens of thousands of lives in Africa,” she added.

Africa bears the greatest burden of malaria worldwide. Global efforts in the last 15 years have led to a 62 per cent reduction in malaria deaths from 2000 to 2015, yet approximately 429,000 people died of the disease in 2015, the majority of them young children in Africa.

The programme will assess whether the vaccine’s protective effect in children from 5 – 17 months old during Phase 3 testing can be replicated in real-life.

Specifically, the pilot programme will assess the feasibility of delivering the required four doses of RTS, S, the vaccine’s potential role in reducing childhood deaths, and its safety in the context of routine use.

RTS, S was developed by GSK and is the first malaria vaccine to have successfully completed a Phase three clinical trial.

The trial was conducted between 2009 and 2014 through a partnership involving GSK, the PATH Malaria Vaccine Initiative (with support from the Bill & Melinda Gates Foundation), and a network of African research sites in seven African countries—including Ghana, Kenya, and Malawi.

RTS, S is also the first malaria vaccine to have obtained a positive scientific opinion from a stringent medicines regulatory authority, the European Medicines Agency (EMA).

The opinion indicated that, in EMA’s assessment, the quality of the vaccine and its risk-benefit profile was favourable from a regulatory perspective.

It said two independent WHO advisory groups, comprised of the world’s foremost experts on vaccines and malaria, recommended pilot implementation of RTS, S in three to five settings in sub-Saharan Africa, in October 2015.

The recommendation came from the Strategic Advisory Group of Experts (SAGE) on Immunisation and the Malaria Policy Advisory Committee (MPAC), following a joint review of all available evidence on the vaccine’s safety and efficacy. WHO formally adopted the recommendation in January 2016.

The three countries were selected based on the high coverage of long-lasting insecticidal nets (LLINs); well-functioning malaria and immunisation programmes, a high malaria burden even after scale-up of LLINs, and participation in the Phase three RTS, S malaria vaccine trial.

It said each of the three countries would decide on the districts and regions to be included in the pilots.

High malaria burden areas will be prioritized, as this is where the benefit of the vaccine is predicted to be highest.

Information garnered from the pilot will help to inform later decisions about potential wider use of the vaccine.

The malaria vaccine will be administered via intramuscular injection and delivered through the routine national immunisation programmes.

WHO is working with the three countries to facilitate regulatory authorisation of the vaccine for use in the pilots through the African Vaccine Regulatory Forum (AVAREF).

It said regulatory support will also include measures to enable the appropriate safety monitoring of the vaccine and rigorous evaluation for eventual large scale use.

Gavi, the Vaccine Alliance, the Global Fund to Fight AIDS, Tuberculosis and Malaria and UNITAID are partnering to provide $ 49.2 million for the first phase of the pilot programme (2017-2020), which will be complemented by in-kind contributions from WHO and GSK.
