For the full list of excipients, see section " Pharmaceutical particulars".

Pharmaceutical form

Lyophilisate and solvent for suspension.

Lyophilisate: off-white to light pink-coloured pellet.

Solvent: colourless solution.

Clinical particulars

Target species

Cattle.

Indications for use

Active immunisation of cattle to reduce the intensity and duration of the clinical respiratory signs induced by an infection with BHV-1 and to reduce nasal excretion of field virus.

Onset of immunity:

An increase in immunity was demonstrated 4 days after intranasal vaccination and 14 days after intramuscular vaccination of 3 month old seronegative animals.

Duration of immunity:

After intranasal administration to 2 week old calves without maternal antibodies, immunity lasts at least until the age of 3-4 months, when the animals should be revaccinated. In the presence of maternally derived antibodies, the protection of the vaccine may not be complete until this revaccination.

Revaccination at 3-4 months of age results in protective immunity that lasts for at least 6 months.

Single intranasal or intramuscular vaccination of 3 month old animals provides protective immunity (reduction of clinical signs and reduction of viral excretion), which was demonstrated via challenge 3 weeks after vaccination. Reduction of viral excretion is maintained for at least 6 months after single vaccination.

Specific information:

No information is available on the efficacy of the vaccine to prevent a latent wild virus infection or to prevent wild virus re-excretion in the latent carrier.

Contra-indications

None.

Special warnings for each target species

The presence of maternal antibodies can influence the efficacy of the vaccination. Therefore it is recommended to ascertain the immune status of calves before vaccination is started.

Animals between the age of 2 weeks and 3 months should be vaccinated via the intranasal route only and the animals should be revaccinated via the intranasal or intramuscular route when the animals are 3-4 months old.

Special precautions for use

Special precautions for use in animals

Vaccinate only healthy animals.

After intranasal administration, the vaccine virus may spread to in-contact cattle. Cattle which need to remain totally free from BHV 1 antibodies should be separated from intranasally vaccinated animals.

Operator warnings:

In case of accidental self injection, seek medical advice immediately and show the package leaflet or the label to the physician.

Adverse reactions

A slight transient rise in temperature (1 °C) can occur up to 5 days post vaccination.

An increase of nasal discharge can be observed after intranasal vaccination.

Use during pregnancy, lactation or lay

Can be used during pregnancy and lactation.

No information is available on the use of this vaccine in breeding bulls.

Interactions

Safety and efficacy data -in cattle from 3 weeks of age onwards- are available which demonstrate that this vaccine can be administered on the same day but not mixed with Bovilis Bovipast RSP.

Safety and efficacy data are available which demonstrate that for the 6-monthly intramuscular revaccination - in cattle from 15 months of age onwards (i.e. those that have previously been vaccinated separately with Bovilis IBR marker live and Bovilis BVD) - this vaccine can be mixed and administered with Bovilis BVD. The product literature of Bovilis BVD should be consulted before administration of the mixed products. The adverse effects observed after administration of one dose or an overdose of the mixed vaccines are not different from those described for the vaccines administered separately.

When mixed with Bovilis BVD at re-vaccination, the demonstrated efficacy claims for Bovilis IBR marker live are as follows:

- Active immunisation of cattle to reduce the fever induced by an infection with BHV-1 and to reduce nasal excretion of field virus.

- Duration of immunity : 6 months demonstrated by serological data.

No information is available on the safety and efficacy of this vaccine when used with any other veterinary medicinal product except the products 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.

Do not use together with immunosuppressive agents.

Amounts to be administered and administration route

Reconstitute the vaccine with the solvent Unisolve.

Dosage: a single dose of 2 ml reconstitued vaccine per animal.

Method of administration:

- from the age of 3 months onwards: intranasal or intramuscular.

- at an age between 2 weeks and 3 months: intranasal.

For intranasal administration (1 ml in each nostril), the use of a nozzle is recommended.

Vaccination schedule:

- Basic vaccination:

Vaccinate each animal with one single dose.

- Revaccination:

When the first vaccination is given between the age of 2 weeks and 3 months, the animals should be revaccinated with a single dose at the age of 3-4 months. Afterwards, revaccinate every 6 months.

When vaccination is started after the animals are 3 months old, the animals should be revaccinated with a single dose every 6 months.

For the 6-monthly revaccination, the vaccine may be reconstituted shortly before use with Bovilis BVD for use in cattle from 15 months of age (i.e. those that have previously been vaccinated separately with Bovilis IBR marker live and Bovilis BVD) and the following instructions should be used:

A single dose (2 ml) of Bovilis IBR marker live mixed with Bovilis BVD is given intramuscularly.

A single dose (2 ml) of Bovilis IBR marker live mixed with Bovilis BVD is given intramuscularly.

Use sterile vaccination equipment free from disinfectants. To prevent the spread of any infective agents the intranasal equipment should be changed at each animal.

Visual appearance after reconstitution

- In Unisolve: colourless to slightly opaque solution.

- In Bovilis BVD: as specified in the product information for Bovilis BVD alone.

Overdose

At 10-fold overdose, no other effects than described under section "Adverse reactions" have been observed.

Withdrawal periods

Zero days.
