Exactly!
Less lethal strains of hpai have been known to protect birds from the more lethal strain, however live strains like this are dangerous as they are coronaviruses which mutate and exchange dna with each other readily, so todays beneficial strain may be tomorrows pandemic.
The EU has an avian vaccine for domestic flocks, but the USDA has only began developing a vaccine as of last year.
The USDA has never considered the lives of poultry of high importance, instead focusing on culling to limit the chance of human transmission, hence their apathy towards developing a vaccine, however this is a poor strategy.
Wild bird populations pose less of a zoonotic risk compared to domestic poultry, backyard flocks are theoretically a higher risk except owners are quicker to notice a problem, quarantine, and treat “if it’s treatable” when it arises compared to commercial flocks where a disease is already rampant by the time an issue is discovered. It makes more sense to vaccinate commercial and backyard flocks rather than repeatedly cull because it’s pointless now that the virus more or less endemic everywhere.
We can’t keep culling and repopulating, it doesn’t work.
I would go a step further..it's not just the USDA that under values poultry... it's the wider medical community as well. Try to find a vet willing to assist a pet chicken/goose/duck. It's very disappointing.
