For subcutaneous use.
Entire male pigs from 8 weeks of age onwards should be vaccinated with 2 doses of 2 ml at least 4 weeks apart, with the second dose given 4 to 6 weeks prior to slaughter. If slaughter is intended to be later than 10 weeks after the second dose a third dose should be given 4 to 6 weeks before the planned slaughter date. In case of suspected misdosing, the animal should be revaccinated immediately.
Female pigs from 10 weeks of age onwards should be vaccinated with 2 doses of 2 ml administered approximately 4 to 8 weeks apart. In case of suspected misdosing, the animal should be revaccinated immediately.
Administer by subcutaneous injection in the neck, immediately behind the ear, using a safety vaccinator with a short needle (16G, typically) to give 12 to 15 mm penetration. To avoid intramuscular deposition and lesions, it is recommended to use a shorter needle to give 5 mm to 9 mm penetration in undersized pigs and pigs younger than 16 weeks of age. Note that when using a safety vaccinator part of the needle will be covered by the needle guard and will not penetrate the pig. Depending on the type of safety vaccinator, pressure may also be put on the skin to push the needle a few millimetres deeper into the tissue. These circumstances should be taken into account when choosing an appropriate needle length. Follow instructions for proper subcutaneous injection provided with the device used. Avoid introduction of contamination. Avoid injecting pigs that are wet and dirty. Allow the vaccine to reach room temperature (15-25 ˚C) before administration.
