Australia Gets World First Sheep Worm Vaccine

05 November 2014

AUSTRALIA – A common and costly parasite to graziers in eastern Australia has a new control method in the form of the world’s first ever sheep worm vaccine.

Barber’s Pole, which can lead to deaths in sheep, has a vaccine working at 75 to 95 per cent efficacy.

Having a new mode of action will help manage drench resistance, experts say.

Researched at the Moredun Research Institute, Scotland, the vaccine should be a solution to a common problem in Australian regions with wet summers, typically Queensland and northern New South Wales.

According to Meat and Livestock Australia consultants, the vaccine should be targeted at lambs, with use in yearling and adult sheep still to be finalised.

Administered as five subcutaneous 1 millilitre injections six weeks apart, the product is registered for lambs.

“In most cases, the first vaccination will be given at lamb marking, and the second injection 3–5 weeks later,” advised an MLA spokesperson.

“The third vaccination is generally at weaning, in most cases with a drench to ensure that the vaccine is not over-whelmed by existing barber’s pole burdens, and to control other worms such as Trichostrongylus or black scour worm.”

Two more vaccinations are given at 6-weekly intervals after the third vaccination.

This will provide cover for the typical risk season which runs December to April, through Australia’s warmer months.
