Description
Target species Susceptible female breeding sheep
Cevac Chlamydia for the active immunisation of susceptible breeding female sheep to reduce abortion caused by Chlamydophila abortus infection.
Contra-indications
Do not vaccinate animals less than 4 weeks before mating. Do not vaccinate pregnant animals. Do not vaccinate animals which are being treated with antimicrobials, particularly tetracyclines.
Special warnings for each target species
Chlamydophila abortus is only one of the causes of abortion in sheep. If abortion rates remain unchanged in flocks which have been vaccinated with Cevac® Chlamydia it is recommended that veterinary advice is sought. The epidemiology of abortion due to Chlamydophila abortus in ewes involves a long incubation period. Ewes that abort in any lambing season have usually been infected at the previous lambing. Field trial data indicate that vaccinating incubating ewes will reduce the incidence of abortion, but a proportion can still go on to abort. Care should be taken in handling such abortions as susceptible humans may be at risk of infection.
Special precautions for use, including special precautions to be taken by the person administering the medicinal product to animals
- Special precautions for use in animals Not applicable.
- Special precautions to be taken by the person administering the medicinal product to animals
Cevac® Chlamydia should not be handled by pregnant women or women of child bearing age as the vaccine may cause abortion. Cevac® Chlamydia should not be handled be persons who are immune-deficient (e.g. AIDS sufferers, persons undergoing chemotherapy or taking immune-suppressive drugs.) If in any doubt, you should consult your GP. Operators should wear gloves when handling the vaccine.
Care should be taken to avoid self-injection, but if this occurs, immediate medical advice should be sought and the doctor informed that self injection with a living Chlamydophila vaccine has occurred. Tetracycline therapy is the current recognised treatment for infection with Chlamydophila abortus in humans.
