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The bottle should be well shaken before any vaccine is withdrawn.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

Basic vaccination scheme:

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

Re-vaccination scheme:

A single dose should be administered every 6 to 12 months after the basic vaccination scheme (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 basic vaccination course before pregnancy.

Adverse reactions

Sheep and cattle:

Very common

(>1 animal / 10 animals treated):

Injection site swelling1,2,6, Injection site induration2,6, Injection site reaction2,6,

Hyperthermia

Common

(1 to 10 animals / 100 animals treated):

Injection site abscess6, Injection site skin discolouration3,6, Injection site pain4,6

Very rare

(<1 animal / 10,000 animals treated, including isolated reports):

Anaphylactic-type reaction5,6

1Such a swelling may reach up to a mean value of 6 cm in diameter in sheep and 15 cm (sometimes up to 25 cm) in diameter in cattle.

2Most local reactions will resolve within 3-6 weeks in sheep and in less than 10 weeks in cattle but may persist longer.

3Returns to normal as the local reaction resolves.

4For 1 – 2 days post first vaccination.

5 If such reaction occurs, appropriate treatment such as adrenaline should be administered without delay.

6The local reactions do not affect the general health, demeanour, feeding or weight gain of the animals.

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 the national competent authority via the national reporting system.

4.3 Contraindications

Do not use in sick or immunodeficient animals.

4.4 Special warnings for each target species

Vaccinate healthy animals only.

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. novyi type B, C. perfringens type A (calves only), C. chauvoei (lambs only) and C. perfringens type 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 basic 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

Not applicable.

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.

Very commonly, animals vaccinated with Covexin 10 may experience reactions to vaccination. These reactions are usually localised swelling, induration or other reaction in the underlying tissue at the injection site (very commonly) but may also include mild hyperthermia (very commonly).

Swelling at the injection site occurs very commonly. This swelling may reach up to a mean value of 6 cm in diameter in sheep and 15 cm in diameter in cattle; though some cattle reactions of up to 25 cm in diameter may be observed. Most local reactions resolve within 3-6 weeks in sheep and in less than 10 weeks in cattle but may persist longer. Commonly, an abscess may develop in some animals.

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

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

The frequency of adverse reactions is defined using the following convention:

- very common (more than 1 in 10 animals treated displaying adverse reaction(s))

- common (more than 1 but less than 10 animals in 100 animals treated)

- uncommon (more than 1 but less than 10 animals in 1,000 animals treated)

- rare (more than 1 but less than 10 animals in 10,000 animals treated)

- very rare (less than 1 animal in 10,000 animals treated, including isolated reports).

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

Basic vaccination scheme:

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

Re-vaccination scheme:

A single dose should be administered every 6 to 12 months after the basic vaccination scheme (see also point 4.2).
