4. CLINICAL PARTICULARS

4.1 Target species

Sheep and cattle

4.2 Indications for use, specifying the target species

For the active immunisation of sheep and cattle against diseases associated with infections caused by Clostridium perfringenstype A, C. perfringens type B, C. perfringenstype C, C. perfringenstype D, Clostridium chauvoei, Clostridium novyi type B, Clostridium septicum,Clostridium sordelliiand Clostridium haemolyticumand against tetanus caused by Clostridium tetani.

For the passive immunisation of lambs and calves against infections caused by the above mentioned clostridial species (except C. haemolyticum in sheep).

The onset of immunity is two weeks after the primary course.

Duration of active immunity

An anamnestic humoral immune response (immunological memory) to all components was demonstrated 12 months following the primary course of vaccination.

As demonstrated by serology/persistent antibody titre only:

Sheep: 12 months against C. perfringens type A, B, C and D, C. novyitype B, C. sordellii, C. tetani

< 6 months against C. septicum, C. haemolyticum, C. chauvoei

Cattle: 12 months against C. tetaniand C. perfringens type D

< 12 months against C. perfringens type A, B and C

< 6 months against C. novyi type B, C. septicum, C. sordellii, C. haemolyticum, C. chauvoei

Duration of passive immunity as demonstrated by serology/persistent antibody titre only is

For lambs:

At least 2 weeks for C. septicum and C. chauvoei, at least 8 weeks for C. perfringenstype B and C. perfringenstype C and at least twelve weeks for C. perfringenstype A, C. perfringenstype D, C. novyitype B, C. tetaniand C. sordellii. No passive immunity was observed for C. haemolyticum.

For calves:

At least 2 weeks for C. sordellii, andC. haemolyticum, at least 8 weeks for C. septicumand C. chauvoeiand at least twelve weeks for C. perfringenstype A, C. perfringenstype B, C. perfringenstype C, C. perfringenstype D, C. novyitype B, and C. tetani.

4.3 Contraindications

None

4.4 Special warnings for each target species

The effectiveness of the vaccine in providing passive immunity to young lambs and calves depends on these animals ingesting adequate amounts of colostrum on the first day of life.

Clinical trials have demonstrated that the presence of maternal antibodies, particularly against C. tetani, C. novyitype B, C. perfringenstype A (calves only), C. chauvoei(lambs only) and C. perfringenstype D may reduce the antibody response to vaccination in young lambs and calves. Therefore, to ensure an optimal response in young animals with high levels of MDA, the primary vaccination should be delayed until the levels wane (which is after about 8-12 weeks of age, see section 4.2).

4.5 Special precautions for use

Special precautions for use in animals

Do not vaccinate sick or immunodeficient animals.

Special precautions to be taken by the person administering the veterinary medicinal product to animals

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

4.6 Adverse reactions (frequency and seriousness)

In the event of an anaphylactic reaction appropriate treatment such as adrenaline should be administered without delay.

75 - 100% of animals vaccinated with Covexin 10 may experience reactions to vaccination. These reactions are usually localised swelling or induration at the injection site but may also include mild hyperthermia, abscess or other reaction in the underlying tissues at the injection site.

Swelling at the injection site occurs in the majority of animals. This may reach up to a mean value of 6 cm in sheep and 15 cm diameter in cattle; occasionally reactions of up to 25cm diameter may be seen in cattle. Most local reactions resolve within 3-6 weeks in sheep and in less than 10 weeks in cattle, but may persist longer in a minority of animals. An abscess may develop in some animals. Vaccination may give rise to reactions in the underlying tissues at the injection site.

Skin discolouration at the injection site (which returns to normal as the local reaction resolved) may occur. Localised pain at the injection site for 1-2 days post first vaccination may occur.

The local reactions do not affect the general health, demeanour, feeding or weight gain of the animals.

4.7 Use during pregnancy, lactation or lay

Pregnancy:

No side effects other than those described under 4.6 were seen when the vaccine was used in sheep and cattle between 8 and 2 weeks prior to parturition. In the absence of specific data, no recommendation can be made for use of the vaccine during the first or second third of pregnancy.

Avoid stress in pregnant ewes and cows.

4.8 Interaction with other medicinal products and other forms of interaction

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.

4.9 Amounts to be administered and administration route

Sheep – from 2 weeks of age

Dose- 1 ml

Cattle – from 2 weeks of age

Dose– 2 ml

Administration:By subcutaneous injection at a suitable site. The recommended site is the loose skin on the side of the neck.

The bottle should be well shaken before any vaccine is withdrawn.

Syringes and needles should be sterile before use and the injection should be made through an area of clean, dry skin taking precautions against contamination.

Primary vaccination:Two doses should be administered, 4-6 weeks apart (see section 4.2 and 4.4).

Booster vaccination:A single dose should be administered at 6 to 12 month intervals (see also point 4.2).

Use in pregnancy

To provide passive protection of the offspring, via the colostrum, a single booster dose should be administered between 8 and 2 weeks before parturition, provided that animals have received a full primary vaccination course before pregnancy.

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary

In calves and lambs, local reactions may increase slightly if twice the recommended dose is administered (refer to section 4.6)

4.11 Withdrawal period(s)

Zero days.
