Clinical information

Bovilis Huskvac Oral Suspension for Cattle — SPC Details

Source: VMD Summary of Product Characteristics (SPC). Last updated 27 Mar 2026.

Duration of immunity: Lungworm immunity is maintained from season to season by
the exposure to lungworm larvae, which in most cases occurs from the grazing of
normal pastures. If such exposure does not occur, a single booster dose is required
prior to each season's turnout.

One dose: 25 ml.
Vaccinate healthy animals of 8 weeks of age and older.
Shake bottle well immediately before use.
Vaccination regime
Basic vaccination scheme
Two doses at a dosage interval of approximately 4 weeks.
Revaccination
Lungworm immunity is maintained from season to season by the exposure to
lungworm larvae, which in most cases occurs from the grazing of normal pastures
after vaccination. Under these conditions of exposure, revaccination is generally not
required.
A single dose of this vaccine prior to each season’s turnout will boost immunity where
such exposure has not occurred, e.g. extensive use of anthelmintics or if using
reserved or clean pasture for a large part of the grazing season.

Do not use in calves showing any signs of illness, particularly those exhibiting any
signs of respiratory distress.

Cattle:
Very rare
(<1 animal / 10 000 animals
treated, including isolated reports):
Cough
.
May occur approximately 7 days after either dose. Transient episodes, which
usually subside in a few days.
Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to
either the marketing authorisation holder or its local representative or the national
competent authority via the national reporting system. See the package leaflet for
respective contact details.

Vaccinate healthy animals only.
Routine vaccination of housed or suckled young stock prior to exposure to field
lungworm challenge will help protect the calves and help reduce the levels of pasture
contamination with lungworm larvae. However, owing to the ability of lungworm
larvae to survive on pasture, calfhood vaccination programmes to control lungworm
infection can only be successful if all susceptible calves are vaccinated in the spring
before exposure to natural field infection occurs at turnout or weaning.
A good immune response is reliant on the reaction of an immunogenic agent and a
fully competent immune system. Immunogenicity of the vaccine antigen will be
reduced by poor storage or inappropriate administration. Immunocompetence of the
animal may be compromised by a variety of factors including poor health, nutritional
status, genetic factors, concurrent drug therapy and stress.

Special precautions for safe use in the target species:
Following vaccination, vaccinated stock should not be mixed with unvaccinated stock
or allowed to graze on pastures recently used by unvaccinated stock until 2 weeks
after the second dose of this vaccine.
Note: For optimum benefit it is important that the calf is exposed to pasture carrying
some infection after this time, as this low-level exposure enhances the immunity
induced by vaccination with this vaccine.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
Wash hands after use.
Special precautions for the protection of the environment:
Not applicable.

No information is available on the safety and efficacy of this vaccine when used with
any other veterinary medicinal product. 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.
To ensure residual effects of long-acting anthelmintics and endectocides or sustained
release bolus preparations do not interfere with the development of immunity
following lungworm vaccination, avoid vaccination during the period of their activity,
and do not use these veterinary medicinal products until 14 days after the second
dose of this vaccine.

Store in a refrigerator (2 °C – 8 °C).
Do not freeze.

Zero days.
