Special precautions for use in animals
In case of accidental self-injection, seek medical advice immediately and show the package leaflet or the label to the physician.
A diffuse hard or soft swelling (max. diameter 5 cm) may occur at the injection site, regressing within 2 days. In very rare cases a local reaction exceeding 5 cm and possibly persisting longer than 2 days may occur. Pain at the injection site can occur in rare cases which may result in temporary functional discomfort (stiffness). In very rare cases, fever, sometimes accompanied by lethargy and inappetence may occur for 1 day, and up to 3 days in exceptional circumstances.
Use during pregnancy, lactation or lay
Can be used during pregnancy and lactation.
Safety and efficacy data are available which demonstrate that this vaccine can be administered on the same day but not mixed with Tetanus Antitoxin Behring (see section "Amounts to be administered and administration route").
No information is available on the safety and efficacy of this vaccine when used with any other veterinary medicinal product except the product mentioned above. A decision to use this vaccine before or after any other veterinary medicinal product therefore needs to be made on a case by case basis.
Amounts to be administered and administration route
Primary vaccination course
Administer one dose (1 ml), by strict intramuscular injection, according to the following schedule:
• Primary vaccination course: first injection from 6 months of age, second injection 4 weeks later.
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 schedule).
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 schedule).
Vaccination schedule table - Equilis prequenza TE
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.
Following the administration of a double dose of vaccine, no side-effects other than those described in section "Adverse Reactions" have been observed except for some depression at the day of vaccination.
To stimulate active immunity against Equine influenza and tetanus.
