Pfizer Animal Health has announced the launch of Poulvac E. coli, the first spray vaccine against avian pathogenic Escherichia coli (APEC) for the poultry industry to be approved in the European Union.

Poulvac E. coliThis new vaccine is based on a European E. coli isolate, and has been shown to provide a broad protection against field infections found in the region.

According to the company, it can be administered from one day of age, and studies have shown that it generates a strong immune response that reduces mortality for up to 12 weeks.

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.

This vaccine represents the first effective vaccine that can be administered en masse to birds to prevent often devastating infections with E. coli in poultry. It represents an innovation for the market as the first ever product to be administered by coarse spray, claims Pfizer.

According to Erik Uyttebroek, marketing director at Pfizer Poultry EuAfME, the product provides a new preventative option for both producers and veterinarians.

He explained: “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. For these businesses, Poulvac E. coli will provide an effective means of controlling APEC and improving animal health and welfare.”

Spraying poultryMr Uyttebroek believes the new vaccine will be particularly useful for protecting high value birds, such as replacement layers and breeders, which have a relatively long life span.

He said: “Some producers have tried to use auto-vaccines to protect their flocks against APEC, but this means injecting birds individually, which is far from ideal. Plus, these vaccines can also cause unwanted reactions in some birds. Poulvac E. coli represents an effective and less labour intensive alternative.”

Poulvac E. coli has been available to US poultry producers for more than two years and is also licensed in a number of Latin American countries.
