Active immunisation of horses from 6 months of age against equine influenza to reduce clinical signs and virus excretion after infection, and active immunisation against tetanus to prevent mortality.

Amounts to be administered and administration route

Intramuscular use.
Allow the vaccine to reach room temperature before use.
Vaccination schedule:
  • Primary vaccination course
Administer one dose (1 ml), strictly intramuscularly according to the following schedule:
∙ Primary vaccination course: first injection from 6 months of age, second injection 4 weeks later.
  • Revaccination
The first revaccination (third dose) against equine influenza is given 5 months after the primary vaccination course. This revaccination results in immunity to equine influenza lasting at least 12 months.
The second revaccination is given 12 months after the first revaccination.
The alternate use, at 12 months interval, of a suitable vaccine against equine influenza, containing the strains A/equine-2/South Africa/4/03 and A/equine-2/Newmarket-2/93, is recommended to maintain immunity levels for the influenza component (see scheme).
The first revaccination is given not later than 17 months after the primary vaccination course.
Thereafter a maximum interval of two years is recommended (see scheme).

In case of increased infection risk or insufficient colostrum intake, an additional initial injection can be given at the age of 4 months followed by the full vaccination programme (Primary vaccination course at 6 months of age and 4 weeks later).
  • Concurrent active and passive immunisation (emergency vaccination)
The vaccine can be used together with Tetanus Antitoxin Behring for treatment of injured horses that have not been immunised against tetanus. In that case, the first dose (V1) of vaccine can be given concurrently with the appropriate prophylactic dose of Tetanus Antitoxin Behring at a separate injection site, using separate syringes and needles. This will lead to a passive protection against tetanus for at least 21 days after concurrent administration. The second dose of the vaccine (V2) should be administered 4 weeks later. A third vaccination with Equilis Prequenza Te should be repeated at least four weeks later. Concurrent use of Equilis Prequenza Te and Tetanus Antitoxin Behring may reduce active immunity against tetanus compared to horses vaccinated with Equilis Prequenza Te in the absence of tetanus antitoxin.
