Just read that Canada and Mexico vaccinate for bird flu and American egg farms don’t.
Apparenty the vaxes have just been approved here, so it will take a while for industry uptake to happen.
MEXICO – It authorised emergency vaccinations against the highly pathogenic H5N1 bird flu strain earlier this year.
The country is currently using two vaccines made by Avimex and Boheringher. By mid-February about 170 million vaccine doses had been administered by certified veterinarians.
Mexico, which has 557 million birds in its poultry industry, does not export poultry products. It has been forced to cull 5.9 million birds because of bird flu in the latest outbreak.
