Porcilis Glässer vet.
Active substance
ATC code
Species
Pigs and sows.
Indications
Pigs:
Active immunisation of pigs to reduce typical lesions of Glässer’s disease caused by Haemophilus parasuis serotype 5.
Onset of immunity: 2 weeks after completion of vaccination.
Duration of immunity: 14 weeks after completion of vaccination.
Sows:
For passive immunisation of the progeny of vaccinated sows and gilts to reduce infection, mortality, clinical signs and typical lesions of Glässer disease caused by Haemophilus parasuis serotype 5 and to reduce clinical signs and mortality caused by Haemophilus parasuis serotype 4.
Onset of immunity: After birth and sufficient uptake of colostrum.
Duration of immunity has been demonstrated at 4 weeks of age against serotype 4 and at 6 weeks of age against serotype 5.
Dose to be administered and administration route
Allow vaccine to reach ambient temperature. Shake well before use.
Administer 2 ml (one dose) of the vaccine intramuscularly in the neck of the pig.
The vaccine is of benefit when pigs and sows with no or low levels of antibodies against H. parasuis serotype 5 are mixed with animals from or in an environment with higher prevalence of Glässers disease or if the piglets from sows with no or low antibodies are reared in such environment. Vaccination of sows with moderate to high levels of antibodies has not been shown to provide additional protection of the offspring. The control of Glässers disease is also dependent on management factors and reduction of stress.
Antibodies against H. parasuis serotype 5 have been shown to be cross-reactive against H. parasuis serotype 4.
Vaccination scheme pigs:
Vaccinate pigs of at least five weeks of age twice with an interval of two weeks.
Vaccination scheme sows:
Vaccinate sows at 6 to 8 weeks before expected time of farrowing twice with an interval of four weeks.
Revaccination scheme sows:
For sows vaccinated during the previous pregnancy, a single revaccination at 4 to 2 weeks before farrowing is recommended.
Adverse reactions
Pigs:
A transient increase in temperature (≤ 2°C) in combination with signs of general discomfort, such as less activity, depression and vomiting may occur on the day of vaccination. The next day the animals are back to normal. Local reactions (painless reddish swellings of 2,5-7,5 cm) may be observed in some pigs until 3 days after vaccination. Systemic anaphylactic reactions may occur in very rare cases (e.g. less than 1 animal in 10,000 animals).
Sows:
A transient increase in temperature may occur (mean 0.9°C, with individual animals displaying a temperature increase of above 2°C). A tendency to lie down, reduced feed and water intake and minor signs of illness may be observed 1 to 2 days after vaccination. All animals return to normal within 1 to 3 days after vaccination. Transient local reactions consisting mostly of non-painful swellings with a diameter smaller than 10 cm may be observed. In some cases swelling may be warm, red and painful with a size larger than 10 cm. These local reactions disappear or clearly diminish 14 days after vaccination.
