CLINICAL PARTICULARS 4.1 TARGET SPECIES Susceptible female breeding sheep. 4.2 INDICATIONS FOR USE, SPECIFYING THE TARGET SPECIES For the active immunisation of susceptible female breeding sheep to reduce abortion caused by _Chlamydophila abortus _infection. Challenge studies have demonstrated that protection against Enzootic abortion and excretion of _Chlamydophila abortus _post-challenge is undiminished for at least three years post vaccination with Enzovax. Field studies in endemically infected flocks maintaining a policy of vaccinating incoming ewes with Enzovax indicate that enzootic abortion levels remain very low in ewes vaccinated 4 years previously. 4.3 CONTRAINDICATIONS Do not vaccinate pregnant animals. Do not vaccinate animals less than 4 weeks before mating. Do not vaccinate animals which are being treated with antibiotics, particularly tetracyclines. 4.4 SPECIAL WARNINGS FOR EACH TARGET SPECIES _Chlamydophila abortus _is only one of the causes of abortion in sheep. If the abortion rate remains unchanged in flocks which have been vaccinated with Enzovax 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 Amended pages: February 2022 AN: 01623/2021 Page 2 of 6 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 Lugege kogu dokumenti
