April 20, 2023 -- The University of Oxford-developed and Serum Institute of India PvT Ltd (SIIPL)- manufactured and scaled up R21/Matrix-MTM malaria vaccine, leveraging Novavax’s adjuvant technology, has been licensed for use in Ghana by the country’s Food and Drugs Authority.

This marks the first regulatory clearance for the R21/Matrix-M malaria vaccine for use in any country. The successful registration was notified to SIIPL by the FDA Ghana. SIIPL is the manufacturing and commercialisation license holder for the vaccine. The vaccine has been approved for use in children aged 5 to 36 months, the age group at highest risk of death from malaria. It is hoped that this first crucial step will enable the vaccine to help Ghanaian and African children to effectively combat malaria. The R21/Matrix-M vaccine has demonstrated high levels of efficacy and safety in Phase II trials, including amongst children who received a booster dose of R21/Matrix-M at one year following a primary three-dose regime.

Professor Adrian Hill, Chief investigator, R21/Matrix-M programme, and Director of the University of Oxford’s Jenner Institute at the Nuffield Department of Medicine, said:

‘This marks a culmination of 30 years of malaria vaccine research at Oxford with the design and provision of a high efficacy vaccine that can be supplied at adequate scale to the countries who need it most. I congratulate our superb clinical trial partners in Africa who have generated the dataset supporting the safety and efficacy of the vaccine in children. As with the Oxford-AstraZeneca COVID-19 vaccine, our partnership with the Serum Institute of India has been key to successful very large-scale manufacturing and rapid development.’

The R21/Matrix-M malaria vaccine is a low-dose vaccine that can be manufactured at mass scale and modest cost, enabling as many as hundreds of millions of doses to be supplied to African countries which are suffering a significant malaria burden.

Oxford researchers and their partners last year reported from a Phase IIb trial that a booster dose of R21/Matrix-M at one year following a primary three-dose regime maintained high efficacy against malaria, and continued to meet the World Health Organization’s Malaria Vaccine Technology Roadmap goal of a vaccine with at least 75% efficacy. This followed 2021 results from the Phase-IIb trial reporting that R21/Matrix-M demonstrated high-level efficacy of 77%. Recent data from the large phase III trial also show high levels of efficacy and a reassuring safety profile.

Notably, Serum Institute of India Pvt Ltd (SIIPL) has provided vaccine and sponsored Phase III licensure clinical trials, demonstrating its commitment to combatting malaria. SIIPL has already established potential manufacturing capacities of more than 200 million doses annually.

This breakthrough is a critical step towards reducing over half a million malaria-related deaths annually and improving the health outcomes of millions of people in Africa and beyond.
