Tridge summary

French duck farmer Herve Dupouy is advocating for the use of vaccines to control the spread of avian flu, a practice that is being reconsidered by governments worldwide due to the disease's recurrence and potential risks. The severe bird flu outbreak of recent years has led to the culling of millions of birds and concerns about the virus's endemicity and possible human transmission. While many countries are shifting their stance on vaccines, the United States remains hesitant. The disease has significantly impacted poultry farms globally, leading to over 200 million birds dead or culled, and sparking concerns about egg prices and the global food crisis.

The US Department of Agriculture expresses concerns that vaccines could mask the spread of the virus and negatively affect trade.
