South Africa Launches Locally-Produced Foot-and-Mouth Disease Vaccine After 21 Years of Research

Understanding Foot-and-Mouth Disease in South Africa

Foot-and-Mouth Disease (FMD), a highly contagious viral infection affecting cloven-hoofed animals such as cattle, sheep, goats, and pigs, has long posed a significant threat to South Africa's livestock sector. The disease, caused by the Aphthovirus genus of the Picornaviridae family, leads to painful blisters in the mouth and feet, fever, reduced milk production, and weight loss, severely impacting animal welfare and farm productivity. In South Africa, where the livestock industry contributes approximately R80 billion annually to the economy, FMD outbreaks disrupt exports, domestic markets, and rural livelihoods. Recent outbreaks since 2019 have affected eight provinces, resulting in over R821 million in lost export revenue alone, with individual dairy cows suffering average losses of R5,000 due to diminished milk yields and treatment costs.

The Southern African Territories (SAT) serotypes—SAT1, SAT2, and SAT3—predominate in the region, distinguishing African FMD epidemiology from Euro-Asiatic strains like O and A found elsewhere. These viruses spread rapidly through direct contact, aerosols, contaminated feed, or fomites, making containment challenging without robust vaccination strategies.

The 21-Year Journey to Local Vaccine Production

South Africa's ability to produce FMD vaccines locally halted in 2005 due to outdated infrastructure at Onderstepoort Biological Products (OBP) that failed to meet international Good Manufacturing Practice (GMP) standards. This left the country reliant on imports, exacerbating vulnerabilities during outbreaks. Research to revive production began between 2010 and 2018 at the Agricultural Research Council Onderstepoort Veterinary Research (ARC-OVR), focusing on four key objectives: identifying candidate vaccine strains matched to regional circulating viruses, adapting them for bioreactor cultivation to boost yields, evaluating immunological and clinical protective immunity, and determining potency and longevity for optimal vaccination schedules.

The breakthrough culminated in February 2026, when ARC-OVR released the first 12,900 doses of a multi-strain vaccine targeting SAT1, SAT2, and SAT3 serotypes. This pilot-scale batch, produced using modern bioreactor technology, underwent rigorous testing for biosafety, biosecurity, and compliance with Act 36 of 1947, marking a proof-of-concept for scaled manufacturing.

Key Players in the Research: ARC-OVR and University Collaborations

The ARC Onderstepoort Veterinary Institute (ARC-OVI), part of the Transboundary Animal Diseases Programme, led the development with scientists like Dr. Faith Peta, Chief Researcher, spearheading the effort. This state-of-the-art campus collaborates closely with the University of Pretoria's (UP) Faculty of Veterinary Science, located adjacent at Onderstepoort. UP's veterinarians provide training, joint research, and expertise in FMD diagnostics and epidemiology, with faculty members frequently contributing to outbreak analyses and vaccine efficacy studies.

These partnerships exemplify how higher education institutions drive applied veterinary research. UP's programs in veterinary tropical diseases have produced experts advancing FMD control, including studies on SAT chimeric vaccines and antigenic matching. For those pursuing careers in this field, opportunities abound in research jobs and faculty positions at South African universities focused on animal health sciences.

Recent publications from ARC-OVR and UP-affiliated researchers, such as those evaluating vaccine efficacy in Africa and monitoring post-vaccination protection, underpin the breakthrough.

Step-by-Step Vaccine Development Process

Developing the Onderstepoort FMD Vaccine involved meticulous steps:

• Strain Isolation and Matching: Identifying SAT1, SAT2, SAT3 viruses circulating in South Africa and neighboring SADC countries, confirmed via collaboration with the Pirbright Institute (UK).
• Cell Culture Adaptation: Adapting viruses to grow efficiently in baby hamster kidney (BHK) cells within bioreactors for higher antigen yields.
• Inactivation and Formulation: Inactivating viruses with binary ethyleneimine (BEI), blending into a trivalent vaccine with adjuvants for enhanced immunity.
• Potency Testing: Animal challenge studies assessing protective dose (PD50), ensuring long-lasting immunity (6-12 months per dose).
• Regulatory Approval: Registration under Act 36, verifying safety, sterility, and efficacy.

This process, refined over years, ensures the vaccine elicits strong humoral and cellular responses superior to some imported alternatives mismatched to local strains.

Launch Details and Initial Distribution

Agriculture Minister John Steenhuisen witnessed the handover on February 6, 2026, hailing it as a shift "from defence to offence" in the FMD war. The initial batch targets high-risk areas: Free State (2,300 doses), Eastern Cape (2,600), North West (2,000), Gauteng (2,000), Limpopo (2,000), and Mpumalanga (2,000). Production ramps to 20,000 monovalent doses weekly from March 2026, scaling to 200,000 by 2027.

Complementing local output, imports from Botswana Vaccine Institute (700,000 doses/month), Biogénesis Bagó (Argentina), and Dollvet (Turkey) bridge immediate gaps amid the ongoing crisis.

Economic and Social Impacts of FMD Outbreaks

FMD's toll extends beyond farms: breeders lose animals, auctioneers see reduced stock, transporters idle, and processors face shortages, rippling through the R80 billion sector. Dairy production plummets 30-50% in affected herds, exports to lucrative markets like the EU halt, and smallholder farmers in communal areas suffer most due to limited biosecurity. The 2025-2026 outbreaks, the worst since 1897, underscore the urgency, with industry bodies like Red Meat Producers Organisation estimating billions in cumulative losses.

The local vaccine promises cost savings (R10-15 per dose vs. imported premiums) and faster deployment, bolstering food security and rural employment.

Stakeholder Perspectives and Industry Reactions

Farmers, Milk SA, and Agbiz welcomed the launch, with Dr. Faith Peta emphasizing self-reliance against regional strains. UP experts like Dr. Jacques van Rooyen (UFS) stress integrated strategies: vaccination, surveillance, and movement controls. Challenges remain, including communal farmer knowledge gaps and illegal animal movements, addressed via education campaigns.

Path to Eradication: The 10-Year National Strategy

South Africa's phased plan targets WOAH FMD-free status with vaccination: Phase 1 mass vaccination in protection zones, surveillance proving no transmission for 12 months; Phase 2 freedom without vaccination. Supported by a National State of Disaster for funding, it integrates private sector vaccines and ARC scaling.

• Short-term: Contain 2026 outbreaks.
• Medium-term: Achieve zonal freedom.
• Long-term: Export certification restoration.

Implications for Veterinary Science and Higher Education

This breakthrough highlights South African higher education's role in agricultural innovation. UP's Faculty of Veterinary Science, with its Onderstepoort campus, trains the next generation of FMD experts, fostering PhD research on novel vaccines like codon-deoptimized live-attenuated strains. Institutions like UP and UFS offer programs in veterinary epidemiology, attracting global talent.

Professionals in higher ed jobs such as lecturer positions in animal health or research assistant roles contribute to such advancements. Explore university jobs in South Africa for veterinary careers.

Global Context and Future Outlook

Africa's FMD burden costs $6.5-21 billion annually in losses and vaccination; South Africa's model could inspire regional hubs. Ongoing research into chimeric vaccines and meta-analyses of efficacy promises even better tools. With scaled production, South Africa eyes FMD freedom by 2036, securing exports and inspiring youth in STEM-ag fields.
