For the full list of excipients, see section 6.1.


3. PHARMACEUTICAL FORM


Suspension for ocular or oral use.

Colourless to white to light beige suspension when shaken.


4. CLINICAL PARTICULARS


4.1 Target species


Chickens.


Indications for use, specifying the target species


For the activeimmunisationof chickens to reduce infection and clinical signs of coccidiosis caused byE. acervulina, E. maxima, E. mitis andE. tenella.

Onset of immunity: 21 days post vaccination.

Duration of immunity: not demonstrated.


4.3 Contraindications


None.



4.4 Special warnings for each target species


The vaccine contains live coccidian oocysts and is dependent upon replication of the vaccinal strains within the chickens for building up of immunity.


It is common to find oocysts in the gastro-intestinal tract of vaccinated birds from 1-3 weeks or more after vaccination. These oocysts are most likely to be vaccinal oocysts which recycle in the birds via the litter. Recycling of oocysts is necessary for the development of immunity and for continued protection.


Since the protection against coccidial infection following vaccination is enhanced by natural challenge, access to any therapeutic agents having anti-coccidial activity at any time following vaccination can adversely affect the development of immunity. This is important throughout the life of the chicken.


4.5 Special precautions for use


Special precautions for use in animals


Vaccinate healthy birds only.

Vaccinate only chickens floor-reared on litter.

To reduce the chance of coccidial challenge before the onset of immunity, litter should be removed and chicken housing should be thoroughly cleaned between rearing cycles.


Special precautions to be taken by the person administering the veterinary medicinalproduct to animals


When spraying the vaccine onto chicks or onto feed, well-fitting masks and eye protection should be worn by the operator.
W
ash and disinfect hands and equipment after use.


4.6 Adverse reactions (frequency and seriousness)


None known.


4.7 Use during lay


The safety of the veterinary medicinal product has not been established in laying birds.


4.8 Interaction with other medicinal products and other forms of interaction

Do not administer any anticoccidial agents, including sulphonamides before or after vaccination, as doing so will have a negative impact on immunity which is dependent on the recycling of oocysts in the environment.


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


Oral (spray on birds, spray on feed, drinking water) or eye drop.


Vaccination schedule:

Spray on birds, spray on feed and eye drop: administer one dose of vaccine to each chicken from 1 day of age.

Drinking water: administer one dose of vaccine to each chicken from 3 days of age.


Once the 30 ml vial containing either 1000 or 5000 doses is opened, the entire contents must be used.


Spray administration onto feed

Sufficient starter feed for the chicks’ first 12-24 hours should be laid out on paper or plastic along the floor of the poultry house.


Shake the vaccine vial vigorously for 30 seconds before use to re-suspend the oocysts. Dilute the vaccine in water at the rate of approximately 1000 doses in 1 litre of water (5000 doses in 5 litres).To ensure that all oocysts are removed from the vial, rinse it out 2-3 times with water. Spray the oocyst suspension evenly over the surface of the feed using a coarse spray. Ensure a controlled even coverage of the total surface area of the feed available to the chickens. Agitate the applicator reservoir regularly throughout spraying to avoid settling-out of oocysts. Ensure that all available feed is treated and that the total number of doses dispensed matches the number of birds in the house.


Once the vaccine has been diluted for use it should be sprayed immediately onto feed and birds should be placed with access to the feed immediately.


When the treated allocation of feed has been consumed, routine feeding may continue.


Administration via drinking water


For the administration of the vaccine drinkers must be used.

Provide an adequate number of drinkers or drinking space so that all chicks have access to the vaccine suspension and thus can receive the correct dose.

Place the drinkers evenly in the area where chicks are housed.


Water should be withheld for 2 - 4 hours before vaccination.


Preparation of the xanthan gum suspension:


Commercially available xanthan gum can be used.


For 1000 doses put 3 litres of clean drinking water at room temperature in a suitable container and dissolve 5g xanthan gum. For 5000 doses put 15 litres of clean drinking water at room temperature in a suitable container and dissolve 25g xanthan gum.



Prepare the vaccine suspension as follows:

To re-suspend the oocysts, shake the vaccine vial vigorously. Open the vial and pour the whole contents into clean drinking water at room temperature: 2 litres for 1000 doses and 10 litres for 5000 doses. To ensure that all oocysts are removed from the vial, rinse it out 2-3 times with water. Shake the obtained 2 litres (1000 doses) or 10 litres (5000 doses) of vaccine suspensions and transfer gradually into the prepared xanthan gum suspension, mixing thoroughly to ensure a homogeneous suspension.

Mixing the xanthan gum suspension together with the vaccine suspension will result in a final quantity of 5 litres (for 1000 doses) or 25 litres (for 5000 doses) vaccine-xanthan gum suspension. Pour the vaccine-xanthan gum suspension into the drinking equipment.


Administration via spray on chickens.


For each 100 birds a dose volume of about 24 ml of coarse spray suspension has to be prepared.


For spraying on chickens use Brilliant Blue (E133) coloring agent.


Preparation of the coloured diluent:

For 1000 doses put 240 ml of water in a suitable container and add Brilliant Blue (E133) colorant at a concentration of 0.01% w/v.

For 5000 doses put 1200 ml of water in a suitable container and add Brilliant Blue (E133) colorant at a concentration of 0.01% w/v.


Preparation and administration of the vaccine suspension:

Shake the 1000- or 5000- doses vial vigorously to re-suspend the oocysts.

Add the entire content of the vial to the diluent and mix thoroughly. Rinse the vial 3 times with diluent to ensure that all oocysts are removed. Fill the vaccine reservoir of the spraying device with the full volume prepared. Continuously maintain homogeneity of the vaccine suspension. The pressure of the spraying device should be at 3 bars. The spraying device must provide a droplet size of ≥100 µm.

To improve the uniformity of the vaccination maintain the chicks inside the chick box for at least 1 hour in order to let them ingest all the vaccine droplets. Make sure that there is enough light so that the chickens are awake and preen themselves and each other.


Eye-drop administration.


Use a standardised dropper for the eye-drop administration. The exact amount of tap water used

depends on the drop size, specific to the dropper used.

For 1000 doses and a drop size of 0.025 ml: use the vaccine undiluted

For 5000 doses and a drop size of 0.025 ml: add the entire contents of one vial to 100 ml water (total volume 125 ml)


Hold each bird with its head tilted to one side. Allow a singledrop (~0.025 ml) of vaccine suspension to fall freely into the open eye, gently flooding it. The drop (before release) and the dropper tip should not touch the eye surface. Allow the bird to blink before releasing it.


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


No side effects have been observed following administration of a 10 times overdose.


4.11 Withdrawal period(s)


Zero days.


5. IMMUNOLOGICAL PROPERTIES


Pharmacotherapeutic group: immunologicals for Aves, live parasitic vaccines for domestic fowl.

ATCvet code: QI01AN01.


To stimulate active specific immunity to wild strains of E.acervulina, E.maxima, E.tenella and E.mitiswhen ingested by chickens. Vaccination is followed by continuous and lifelong recycling of vaccinal oocysts in birds via the litter. This recycling of oocysts results in the development of immunity and continued protection against wild strains of the four Eimeria strains.
