ASF Vaccines: Vietnam’s Path to Combatting African Swine Fever
Vietnam, a country heavily reliant on pork production, has recently given the green light for the commercial use of the first African Swine Fever (ASF) vaccines. The approval marks a significant step in the ongoing battle against this highly contagious and deadly disease that has devastated pig populations across Asia, including Vietnam.
A Timely Response to a Looming Crisis
ASF, also known as pig Ebola, is a viral disease that affects domestic and wild pigs, resulting in high mortality rates and severe economic losses. Since its first outbreak in China in 2018, ASF has quickly spread throughout the region, including Vietnam, causing the culling of millions of pigs and disrupting pork supply chains.
The Development and Approval of ASF Vaccines
With the aim of controlling the spread of ASF and safeguarding the country’s pork industry, Vietnam’s Ministry of Agriculture and Rural Development has granted commercial approval for the use of two ASF vaccines. These vaccines, developed by Vietnamese researchers in collaboration with international partners, have undergone rigorous testing to ensure their safety and effectiveness.
The first vaccine, developed by the National Institute of Veterinary Research, is a live attenuated vaccine that works by introducing a weakened strain of the ASF virus into pigs’ bodies. This stimulates their immune systems to produce protective antibodies, providing immunity against the disease. The second vaccine, developed by the Institute of Biotechnology, is an inactivated vaccine that contains killed ASF virus particles, stimulating an immune response without causing disease.
Impact on Vietnam’s Pork Industry
The approval of these ASF vaccines is a significant development for Vietnam’s pork industry, which contributes to a large portion of the country’s agricultural economy. The vaccines offer hope for farmers who have suffered heavy losses due to ASF outbreaks. By vaccinating their pigs, they can reduce the risk of infection and potentially resume normal production levels.
Challenges and Next Steps
While the approval of ASF vaccines is a milestone achievement, challenges lie ahead. Mass vaccination campaigns need to be organized to ensure widespread coverage and maximum protection for pig populations. Additionally, continuous monitoring and surveillance of the disease are crucial to detect any potential vaccine failures or new strains of ASF.

The use of ASF vaccines in Vietnam marks a significant step forward in the fight against African Swine Fever. With the ability to protect pig populations from this devastating disease, farmers can begin to rebuild their livelihoods and secure the future of Vietnam’s pork industry. Continued efforts in vaccination, surveillance, and research will help to ensure a sustainable and resilient pig farming sector in the face of this formidable challenge.[1]
