Advantages Glanvac+Eryvac Dual Vaccinator

 This vaccine may be administered with Glanvac vaccine(APVMA No. 53385) using a dual-barrel single needle vaccination device, and has been proven a safe method of vaccination in pregnant ewes. The co-administration of Glanvac vaccine and Eryvac vaccine using a dual-barrel single-needle vaccinator resulted in efficacy (measured using serological outcomes such as antibody titres) that was comparable to that of each vaccine administered separately, with an acceptable safety profile.

Dosage

Dose rate: 1 mL for all classes of sheep.
Injection site: Vaccine should be administered subcutaneously using a shrouded vaccinator and a 6mm (¼ inch) 18 gauge needle on a 45mm degree angle on the side of the neck midway between the ear and the front of the shoulder.

Lambs need two doses:
1. First ‘priming’ dose at marking;
2. Second ‘booster’ dose at weaning.
Previously unvaccinated ewes need two doses:
1. First ‘priming’ dose at the time of joining or scanning;
2. Second ‘booster’ dose approximately 4 weeks before the expected date of lambing.
Other classes of previously unvaccinated sheep need two doses:
1. First ‘priming’ dose;
2. Second ‘booster’ dose approximately 4 weeks after.
Previously vaccinated sheep need ‘annual booster’ vaccinations:
  • For ewes vaccinate 4 weeks before the expected date of lambing.
  • This should pass temporary immunity to their lambs in the colostrum, or first milk, to protect them for the first 6 to 8 weeks of their lives.
