None.
A diffuse hard or soft swelling (max. diameter 5 cm) may rarely occur at the injection site, regressing within 2 days. Pain at the injection site can occur in rare cases, which may result in temporary functional discomfort (stiffness). A local reaction exceeding 5 cm and possibly persisting longer than 2 days may occur in very rare cases. Fever, sometimes accompanied by lethargy and inappetence, may in very rare cases occur for 1 day, and up to 3 days in exceptional circumstances.
The frequency of adverse reactions is defined using the following convention:
very common (more than 1 in 10 animals treated displaying adverse reaction(s))
common (more than 1 but less than 10 animals in 100 animals treated)
uncommon (more than 1 but less than 10 animals in 1,000 animals treated)
rare (more than 1 but less than 10 animals in 10,000 animals treated)
very rare (less than 1 animal in 10,000 animals treated, including isolated reports).
If you notice any side effects, even those not already listed in this package leaflet or you think that the medicine has not worked, please inform your veterinary surgeon.
Horses 
1 ml. Intramuscular 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
It is recommended that a single booster dose should only be administered to horses that have already received a primary vaccination course using vaccines that contain the same types of equine influenza virus included in this vaccine. A primary vaccination course may be considered necessary in horses that have not been suitably primed.
The first revaccination (third dose) 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).
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).
Allow the vaccine to reach room temperature before use.
