France vaccinates its ducks (2023)
France became the first country to run a nationwide poultry vaccination campaign, targeting about 60 million ducks. Ducklings got a two-shot course, mandatory on farms with more than 250 birds.
The United States and Japan limited imports of French poultry, worried that vaccinated birds could hide the virus.
By March 2025, France said the policy had worked and that it had regained bird-flu-free status, letting poultry back outdoors.
France shows both sides of South Africa's bet: vaccination can curb outbreaks, but it can also trigger trade restrictions from cautious buyers.
