Equip EHV 1.4
Active substance
ATC code
Species
Horses.
Indications
For active immunisation of horses to reduce clinical signs due to infection with Equine Herpesvirus 1 and 4 and to reduce abortion caused by EHV-1 infection.
Dose to be administered and administration route
One dose per horse to be administered by deep intramuscular injection.
Primary course: A single dose should be administered from 5 months of age followed by a second injection after an interval of 4 to 6 weeks.
In the event of increased infection risk, for example when a foal had consumed insufficient colostrum or there is a risk of early exposure to field infections with EHV-1 or EHV-4, earlier vaccination may be given. In these circumstances, the foal should receive a single dose from 3 months of age followed by the above mentioned full primary vaccination course.
Booster: Following completion of the primary course, a single dose should be administered every 6 months.
Use in pregnant mares: To reduce abortion due to EHV-1 infection, pregnant mares should be vaccinated during the 5th, 7th and 9th month of pregnancy with a single 1.5 ml dose on each occasion
Adverse reactions
A transient local swelling at the injection site was very commonly observed. Usually, the local swelling does not measure more than 5 cm in diameter and disappears within a few to 6 days post vaccination. A transient increase in rectal temperature during up to 2 days following dosing not exceeding 1.7°C was commonly observed. These clinical signs usually resolve with no need for treatment.
Rarely, stiff gait, anorexia and lethargy have been reported. Hypersensitivity reactions may occur in very rare cases. In case of such reactions, appropriate treatment is recommended.
The frequency of adverse reactions is defined using the following convention:
• very common (more than 1 in 10 animals displaying adverse reaction(s) during the course of one treatment)
• common (more than 1 but less than 10 animals in 100 animals)
• uncommon (more than 1 but less than 10 animals in 1,000 animals)
• rare (more than 1 but less than 10 animals in 10,000 animals)
• very rare (less than 1 animal in 10,000 animals, including isolated reports.
