A freeze-dried polyvalent vaccine containing live attenuated
bluetongue virus strains for the prophylactic immunisation
of sheep against bluetongue.
The vaccine is presented as a series of three separate
injections with different serotypes of bluetongue virus
in each bottle. The bottles are marked A, B and C and
must be injected in the following sequence: A, first,
B, three weeks later, and the bottle marked C three weeks
after B. If necessary, this interval can be longer but
never shorter than three weeks. It is necessary
to inject the full series, A, B and C in order to get
the widest possible protection.
Store
the vaccine in a refrigerator at 4 °C to 8 °C.
Do not use after the expiry date printed on the bottle.
RECOMMENDATIONS FOR USE
Vaccinate sheep from August to October. Immunisation of
ewes should commence 9–12 weeks before mating.
It is not advisable to inject pregnant ewes during
the first half of pregnancy. Rams should be inoculated
after the mating season. Inject lambs from immunised
ewes at the age of six months and older. If done at
an earlier age in heavily infected areas, lambs must be
revaccinated at the age of six months. Sheep must
be vaccinated annually.
N.B.: The
vaccine will only stimulate immunity to all serotypes
after a number of inoculations. Additional
measures must necessarily be taken to ensure protection
of sheep against bluetongue during the time of the year
when the risk of transmission of infection by biting insects
is greatest. Animals should be kept away from low-lying
areas in vleis and next to rivers, dams and pans and valuable
animals should be stabled during late afternoon, night
and early morning.
WARNINGS
Do not slaughter animals for human consumption
within 7 days of vaccination.
Vaccinate healthy animals only.
Keep out of reach of children, uninformed persons and
animals.
Although this product has been extensively tested under
a large variety of conditions, failure thereof
may ensue as a result of a wide range of reasons. If this
is suspected, seek veterinary advice and
notify the registration holder.
DIRECTIONS FOR USE
Use only as directed.
Sterilise syringes and needles by boiling in water for
at least 15 minutes. Do not use disinfectants or methylated
spirits for sterilising either needles or syringes. Use
a separate needle for each animal.
The active ingredient of the vaccine is in the form of
a powder or pellet in a small bottle. By means of a sterile
syringe transfer approximately 1 ml of the 100 ml sterile
diluent to the bottle marked A containing the freezedried
vaccine. Mix thoroughly until the powder is dissolved
and then transfer this suspension back to the remaining
sterile diluent and again mix well by means of the sterile
syringe. The vaccine is now ready for use and must be
injected without delay.
Three weeks later use the bottle marked B. Reconstitute
in the same way as bottle A and inject into 100 sheep
that have been injected with vaccine A. After another
three weeks use bottle C. Follow the same directions as
for A and B and inject the same sheep that have previously
been injected with vaccine A and B.
Shake the bottle well before use. Avoid exposure to high
temperatures and direct sunlight during vaccination.
DOSAGE: 1 ml subcutaneously. Inject
the vaccine behind the shoulder or on the inside of the
thigh but not
under the tail.
EFFECTS OF THE VACCINE
A fever reaction may follow from the seventh day after
vaccination. Such animals must not be exposed to
strong sunlight, adverse weather conditions and fatigue.
A reasonable protection against most of the virus
types is achieved within 3–4 weeks after the last
injection but, however, cannot be guaranteed in all animals.
PACKING
Available in packagings of 100 doses. |
