Pfizer Animal Health has launched Poulvac E. coli, the first spray vaccine against avian pathogenic Escherichia coli (APEC) for the poultry industry to be approved in the European Union.
The product, which is administered via coarse spray, represents the first effective vaccine that can be administered en masse to birds to prevent typically devastating infections with E. coli in poultry.
The vaccine is based on a European E. coli isolate and can be administered from one day of age. The vaccine has a zero-day withdrawal period. Revaccination depending on local field pressure and risk assessment can be considered in consultation with a veterinarian.
“The layer sector has access to very few effective antibiotics that do not cause violative residues in eggs. In fact, in some countries there is no licensed anti-infective at all that can be used in layers to treat diseased birds,” Erik Uyttebroek, marketing director at Pfizer Poultry EuAfME, said in a news release. “This is … the first [modified live vaccine] that you administer directly to the birds you want to protect, rather than vaccinating the breeders and relying on maternal antibodies.”
Poulvac E. coli has been available to American poultry producers for more than two years and is also licensed in several Latin American countries.
