Should nations prioritize livestock vaccination programs over mass culling to control disease outbreaks?

In 2025, international health organizations and several nations expanded the use of high pathogenicity avian influenza (HPAI) vaccines to manage outbreaks. This strategic shift follows a global control initiative for 2024-2033.

Why it matters

Recent outbreaks demonstrated that traditional biosecurity and mass culling measures have significant limitations for disease control. Adopting vaccination strategies aims to better protect poultry populations and reduce the economic instability caused by massive farm losses.

Inactivated vaccines currently dominate the market at 95.5% compared to just 4.5% for vector vaccines. While nations like the Philippines and South Africa have approved these tools, the long-term global impact of the 2024-2033 control strategy remains in the early implementation phase.

The players

World Organization for Animal Health

An intergovernmental organization that develops international standards for animal health and disease control.

Food and Agriculture Organization

A specialized agency of the United Nations that leads international efforts to defeat hunger and improve food security.

United Egg Producers

A U.S. trade association representing the interests of egg farmers and developing safety frameworks.

National Turkey Federation

A U.S. industry group that represents turkey farmers and works on national disease management policies.

The details

Vaccines are administered through various protocols including in ovo injection or farm-level subcutaneous and intramuscular shots. To manage the risk of masked infections, authorities are using the DIVA strategy, which allows researchers to distinguish between birds that are naturally infected and those that have been vaccinated. This approach facilitates ongoing surveillance while providing protective immunity to the flocks.

Timeline

  1. Late 2022: H5N1 was first detected in South America.

  2. 2024-2033: Period for the FAO and WOAH global HPAI control strategy.

  3. 2025: Expanded use of HPAI vaccination was emphasized.

  4. September 2025: FAO Tackling HPAI Together meeting held in Brazil.

The Home Front

The global pivot toward vaccination marks a departure from reliance on mass culling as the sole method for managing widespread avian influenza. This transition aligns with the 2024-2033 global HPAI control strategy to build more resilient food and poultry supply chains.

Poultry owners should monitor official agricultural updates for any new guidance regarding vaccine availability in their region. If you keep backyard birds, focus on maintaining high biosecurity standards while waiting for local veterinarians to update protocols.

The takeaway

The move to vaccination indicates a permanent shift in how countries manage high-pathogen disease outbreaks in agricultural settings. Keep track of updates from your local agricultural extension office or veterinary board for information on how these new vaccination protocols may apply to domestic flocks.
