The first of several new vaccines in development to address Post-weaning  Multisystemic Wasting Syndrome in Canada is getting the go-ahead.

Merial has received a special import permit to allow Canadian distribution of Circovac. Several other companies also are close to releasing vaccines, according to a Reuters' report.  Francois Joisel, Merial's global technical serves director, points out that Circovac is administered to the sow, she then passes protection to her litter.

Joisel says the vaccine has been used in France and Germany for the past 18 months, and more than 350,000 sows have been vaccinated with encouraging results.

The first shipment arrived in Canada about two weeks ago.

PMWS, a condition that affects only pigs, is now a worldwide issue. It was first characterized in Western Canada about a decade ago. It's important to note that there is no impact on pork products or concern for human health.

PMWS symptoms surface between six and 15 weeks of age, when pigs typically enters the early grower phase. Clinical signs may include weight loss, difficulty breathing, enlarged lymph nodes or jaundice.

A recent outbreak in Quebec and Ontario provences has been causing loses that range from 10 percent to as high as 50 percent.

PMWS has surfaced in the United State a bit more intensely in the past couple of months. The hope is that vaccines to address PMWS will become available for U.S producers as well.
