MSD Equilis® Prequenza TE is a vaccine for the active immunisation against equine influenza and tetanus.
Equilis® Prequenza TE is indicated for the active immunisation of healthy horses and ponies against equine influenza. It reduces the severity and duration of clinical signs and reduces the amount and duration of viral shedding after infection. It is also indicated for the active immunisation against tetanus to prevent disease and mortality.
Directions for use – USE ONLY AS DIRECTED.
Basic vaccination course
All horses not previously vaccinated should receive 2 vaccinations with a 4-week interval. The basic vaccination course results in immunity to equine influenza lasting at least 5 months. Foals should be vaccinated from the age of 6 months. If vaccination is performed before 6 months of age full protection can be expected after the third vaccination (first revaccination).
The first revaccination (third dose) is given 5 months after the basic vaccination course. The revaccination with Equilis® Prequenza TE or Equilis® Prequenza results in immunity to equine influenza for at least 12 months.
The second revaccination is given 12 months after the first revaccination.
The alternate use, at 12 months interval, of Equilis® Prequenza is recommended to maintain immunity levels for the influenza component.
Tetanus Basic vaccination course
All horses not previously vaccinated should receive 2 vaccinations of 1 dose with a 4-week interval. The basic vaccination course results in immunity to tetanus for at least 17 months.
The first revaccination for tetanus can be given 17 months after the basic vaccination course. When a third injection with a vaccine containing tetanus is given at 5 months after basic vaccination, the next tetanus vaccination can be administered after 24 months.
In case of increased infection risk or insufficient colostrum intake, an initial injection can be given at the age of 4 months followed by a full vaccination programme.
The vaccine can be used together with tetanus antiserum for the treatment of injured horses that have not been immunised against tetanus. In that case, the first dose of the basic vaccination can be combined with administration of the appropriate prophylactic dose of tetanus antiserum at a separate injection site. The second dose can be administered 4 weeks later as described above. It is recommended to repeat immunisation against tetanus after approximately 1 month.
PREGNANCY AND LACTATION
Can be used in pregnant mares, but handling of such animals, particularly in the later stage of pregnancy, is not without risk and care should be taken to avoid stress.
