Overview of the R21/Matrix-M Malaria Vaccine

The R21/Matrix-M malaria vaccine represents a significant advancement in the fight against malaria. Developed by the University of Oxford in collaboration with the Serum Institute of India, this vaccine incorporates Novavax's innovative adjuvant technology to boost its efficacy.

WHO Approval Status

The World Health Organization (WHO) has officially recommended the use of the R21/Matrix-M malaria vaccine. This endorsement comes after the vaccine satisfied stringent safety, quality, and effectiveness benchmarks set by the WHO.

Approval Process

Before receiving WHO approval, the vaccine underwent a comprehensive scientific evaluation. This assessment was conducted by the WHO's independent advisory body, the Strategic Advisory Group of Experts (SAGE), along with the Malaria Policy Advisory Group (MPAG). Their thorough review process ensured that the vaccine met all necessary criteria for public health.

Vaccine Availability

With the WHO's recommendation in place, additional regulatory approvals are anticipated soon. It is expected that vaccine doses could be available for broader distribution as early as next year, significantly enhancing malaria prevention efforts.

Production Capacity

The Serum Institute has established a robust production capacity, currently able to manufacture 100 million doses annually. This capacity is projected to double within the next two years, highlighting the critical role of large-scale vaccine production in combating malaria.

Role of Novavax

Novavax plays a vital role in this vaccine's formulation through its proprietary saponin-based adjuvant technology, known as Matrix-M. Novavax has licensed this technology to the Serum Institute specifically for use in endemic regions while retaining commercial rights in non-endemic countries.

Development Support

The development of the R21/Matrix-M malaria vaccine was supported by various organizations, including the Jenner Institute at Oxford University and the Serum Institute of India. Key partners in this initiative include the European and Developing Countries Clinical Trials Partnership (EDCTP), the Wellcome Trust, and the European Investment Bank (EIB).
