HPAI vaccination gives South African poultry producers an additional tool for managing Highly Pathogenic Avian Influenza, but vaccination does not prevent the virus from entering an operation. That remains the role of effective poultry biosecurity. Under South Africa’s HPAI Vaccination Framework, producers seeking permission to vaccinate must demonstrate appropriate biosecurity, surveillance, movement control and record keeping. This reinforces an important principle for poultry operations: vaccination and biosecurity perform different functions, and effective disease control depends on both.
South Africa’s HPAI Vaccination Framework Changes the Approach
Agriculture Minister John Steenhuisen amended the Animal Diseases Regulations (R.2026 of 1986) to formalise an HPAI Vaccination Framework under the Animal Diseases Act, 1984, ending the position that mass culling was the only lawful response to an outbreak.
“The old regulations forced the industry to destroy flocks unnecessarily”
– John Steenhuisen
The scale of the 2023 epidemic demonstrates why the change matters. The outbreak cost the poultry industry approximately R10.5 billion and affected more than 9.5 million birds.
HPAI vaccination therefore represents a significant development in South Africa’s disease-management strategy. Importantly, however, the framework does not reduce the biosecurity requirement. It places structured, demonstrable biosecurity at the foundation of vaccination readiness.
What Biosecurity Is Required for HPAI Vaccination?
Approval to vaccinate is granted by the Director: Animal Health per production cycle for a specified property and is valid for 12 months.
Farms must demonstrate biosecurity meeting the South African compartmentalisation standard, VPN 44, or an equivalent standard certified by the consulting veterinarian in consultation with the State Veterinarian.
Requirements include written standard operating procedures covering biosecurity, surveillance and movement control. Weekly post-mortem examinations and organ sampling, monthly tracheal and cloacal swabs, and auditable movement controls are also required.
This makes biosecurity more than an additional precaution surrounding HPAI vaccination. It forms part of the operational foundation required for permission to vaccinate.
Vaccination Protects Birds, Biosecurity Controls Exposure
HPAI vaccination can reduce clinical disease, mortality and viral shedding, but vaccines seldom provide sterilising immunity.
Protection is also generally strain-specific. Birds vaccinated against H5 would carry little to no vaccine protection against H7N6. During the 2023 epidemic, H7N6 killed an estimated six million birds, compared with approximately 1.7 million attributed to H5N1.
Vaccine effectiveness can also be influenced by the match with the circulating strain, vaccine quality and cold-chain integrity, administration technique, timing, maternal antibodies, bird health and stress.
Vaccination is therefore armour for the bird;
biosecurity is stopping the enemy getting into the building.
For poultry producers, this distinction is fundamental. Vaccination can strengthen the bird’s protection, but it cannot close the physical and operational pathways through which infectious material reaches a flock.
Poultry Biosecurity Must Control How Contamination Moves
HPAI can potentially enter and move through poultry operations via wild birds, people and footwear, vehicles, equipment, crates, feed, water, rodents and other pests, as well as contaminated neighbouring properties.
Effective poultry biosecurity must therefore control movement rather than focus on individual cleaning activities in isolation.
Every person, vehicle, crate or piece of equipment moving between uncontrolled and controlled environments creates a potential transfer point. Access controls, personnel hygiene, vehicle and equipment sanitation, crate hygiene, pest management, cleaning and disinfection need to function as connected barriers.
A hygienically prepared poultry house is only as protected as the controls governing what enters it afterwards.
Cleaning and Disinfection Strengthen the Biosecurity Barrier
Effective cleaning and disinfection act before a pathogen reaches the bird by reducing contamination across potential transfer points.
Ecowize’s extensive work within South Africa’s poultry industry provides practical insight into how biosecurity controls need to function across real production environments. Cleaning and disinfection programmes extend beyond poultry houses to vehicles, crates, equipment and movement points, supported by access and hygiene protocols across farms, hatcheries, packing and processing environments.
The effectiveness of these interventions depends on maintaining the integrity of the wider biosecurity system. A disinfected poultry house can be exposed again through contaminated footwear. Sanitised equipment can become a transfer point if it moves through uncontrolled areas. Vehicle hygiene can be undermined when traffic routes allow recontamination.
The objective is not simply to clean individual assets. It is to create and maintain effective barriers between potential contamination and the flock.
Biosecurity Must Be Demonstrable
The HPAI Vaccination Framework requires documented SOPs, surveillance, sampling and auditable movement controls.
This creates an important distinction between having a biosecurity programme and being able to demonstrate that the controls within it are consistently implemented.
Verification and accurate records provide evidence that access, movement, cleaning and disinfection requirements are being followed. They also allow deviations to be identified before weaknesses become established pathways for contamination.
For vaccination-ready operations, documentation should demonstrate operational control rather than exist simply to satisfy an audit.
Strong Biosecurity Is the Foundation for HPAI Readiness
HPAI vaccination changes the disease-management options available to South African poultry producers, but it does not change the fundamentals of preventing exposure.
The strategic priority is not vaccination or biosecurity. It is a layered system in which vaccination, controlled access, movement management, surveillance, cleaning and disinfection, pest management, personnel hygiene and auditable records reinforce one another.
Ecowize’s experience across South African poultry production allows biosecurity requirements to be translated into practical controls that work across the operation. This includes validated cleaning and disinfection, poultry house hygiene, vehicle and equipment sanitation, crate hygiene, access protocols and the verification systems needed to demonstrate consistent control.

Frequently Asked Questions
Does HPAI vaccination replace poultry biosecurity?
No. HPAI vaccination can reduce clinical disease, mortality and viral shedding, but biosecurity remains essential for reducing opportunities for infectious material to enter and spread through a poultry operation.
What biosecurity is required for HPAI vaccination in South Africa?
Farms must meet the South African compartmentalisation standard, VPN 44, or an equivalent standard, alongside defined requirements for biosecurity, surveillance, movement control, sampling and documentation.
How long is HPAI vaccination approval valid?
Approval is granted by the Director: Animal Health per production cycle for a specified property and is valid for 12 months.
How can HPAI enter a poultry operation?
Potential pathways include wild birds, people, footwear, vehicles, equipment, crates, feed, water, rodents, other pests and contamination associated with neighbouring properties.
How do cleaning and disinfection support HPAI biosecurity?
Cleaning and disinfection reduce contamination across poultry houses, vehicles, crates, equipment and other potential transfer points, strengthening the barriers designed to prevent infectious material from reaching the flock.
