For a full list of excipients, see section 6.1.


3.

PHARMACEUTICAL FORM



Lyophilisate for oral suspension.

Light beige to brownish light gray lyophilisate.


4.

CLINICAL PARTICULARS


4.1

Target species



Chickens from one day old (breeders and layers).


4.2

Indications for use, specifying the target species



Active immunization of chickens to reduce colonization, persistence and invasion of the intestinal tract and internal organs by Salmonella Enteritidis and Salmonella Typhimurium.

Onset of immunity within 6 days after first vaccination.


Duration of immunity for Salmonella Enteritidis is 35 weeks after second vaccination and 63 weeks after third vaccination when used according to the recommended vaccination schedule.


Duration of immunity for Salmonella Typhimurium is 60 weeks after third vaccination when used according to the recommended vaccination schedule.


4.3

Contraindications



Do not vaccinate unhealthy chickens or chickens under heavy stress conditions. Do not use in broilers.


4.4


Special warnings



Vaccinated chickens excrete the vaccine strain up to six weeks post vaccination. The vaccine may thus spread to susceptible birds in contact with vaccinated chickens or their manure.


4.5

Special precautions for use



i. Special precautions for use in animals



The use of the vaccine in fancy breeds has not been studied.

Due to the adenine-histidine auxotrophy of the vaccine strain, a differentiation between vaccine and field strains is possible by means of an appropriate growth test.

The vaccine strain is among others sensitive to ampicillin, cefotaxime, chloramphenicol, ciprofloxacin, gentamycin, kanamycin, oxytetracycline, streptomycin.

The vaccine strain is resistant to sulfamerazine alone but sensitive to sulfamerazine and trimethoprime in combination.

The vaccine strain can also be distinguished from the field strain by molecular biology methods, such as restriction fragment polymorphism (RFLP) in pulse gel electrophoresis (PFGE).

The vaccine strain has been shown to spread to non-target species such as calves and pigs. It persisted in these animals and was excreted over a period of 9 days in calves and 22 days in pigs and has been shown to cause a transient increase in body temperature.



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



Use disposable gloves when reconstituting the vaccine. Wash and disinfect hands after handling vaccine.

Do not ingest. If the vaccine has been swallowed seek medical advice. The vaccine strain is sensitive to antibiotics with the exception of sulfamerazine.

Immunocompromised personnel should not handle vaccine or come into contact with vaccinated chickens during the period of excretion of the vaccine strain.


The vaccine strain has been isolated from chicken litter up to 13 days after vaccination and is excreted from vaccinated chickens up to 19 days post vaccination. In studies, the vaccine strain can be found in the environment for up to 8 weeks after the 2nd vaccination and 5 weeks after the third vaccination.

On very rare occasions, the vaccine strain may be isolated from the environment beyond the above mentioned period.


Personnel involved in attending vaccinated flocks should follow general hygiene principles (changing clothes, wearing gloves, cleaning and disinfection of boots) and take particular care in handling litter from recently vaccinated chickens.

Hands should be washed and disinfected after attending vaccinated flocks.


Appropriate veterinary and husbandry measures should be taken to avoid spread to susceptible species.


4.6

Adverse reactions (frequency and seriousness)



None known.


4.7

Use during pregnancy, lactation or lay



Not to be used within 3 weeks (after the third vaccination) or 6 weeks (after the second vaccination) before the onset of the laying and during the laying period.

Unvaccinated birds intended for lay should not come into contact with vaccinated birds.


4.8

Interaction with other medicinal products and other forms of interaction



No anti-infective substances should be used within 3 days before and after immunisation with the vaccine. In case of essential administration, the vaccination of the concerned birds has to be repeated.

No information is available on the safety and efficacy from the concurrent use of this vaccine with any other. Therefore the safety and efficacy of this product when used with any other (either when used on the same day or at different times) has not been demonstrated.


No competitive microflora preparations should be administered concurrently with the product.


4.9


Amounts to be administered and administration route



Immunisation against Salmonella Enteritidis


Recommended vaccination scheme for birds on farms of unknown salmonella status or positive Salmonella Enteritidis detection:

One dose from first day of age, a second dose two weeks later and a third dose not later than three weeks before the laying period. There should be more than two weeks between the second and third administration.


Recommended vaccination scheme for birds on farms with a known history and absence of Salmonella Enteritidis according to routine bacteriological monitoring:

One dose from first day of age followed by a second dose two weeks later. A greater level of protection, with regards to the duration of immunity, is observed with the 3-dose regime.



Immunisation against Salmonella Enteritidis and Salmonella Typhimurium (whatever the salmonella status)


One dose from first day of age, a second dose six weeks later and a third dose around 13 weeks of age.



  • Apply the usual aseptic precautions to all administration procedures.

  • Calculate the number of vials of vaccine required to vaccinate all the birds.

  • Use only clean, antiseptic and disinfectant free drinking water.

  • Reconstitute the vaccine using a small volume of drinking water in the vaccine vial. Ensure the complete dissolution of the lyophilisate. Then add the reconstituted vaccine to sufficient water to be consumed within 4 hours and mix thoroughly.



Administration in drinking water (oral route)

The required number of doses of reconstituted vaccine is added to sufficient water that will be consumed within 4 hours.

Birds may have drinking water withdrawn for 1-2 hours before administering vaccine.


As a guide, administer the vaccine in a volume of at least 2 litres of drinking water per 1,000 chickens at first vaccination and at least 5 litres of drinking water per 1,000 chickens at second vaccination two weeks later.

If a third dose is administered, use at least 10 – 20 litres of drinking water per 1,000 chickens. This third dose should be administered not later than three weeks before the laying period.


4.10

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



Administration of an overdose (10 doses) can occasionally result in loose faeces and in a transient weight loss without any consequences on the final performances.


4.11

Withdrawal period(s)



Meat: 6 weeks from last vaccination.

Eggs: After the two first vaccinations: 6 weeks

After the third vaccination: 3 weeks


5.

IMMUNOLOGICAL PROPERTIES



For active immunisation of chickens against Salmonella Enteritidis and Salmonella Typhimurium.

The live vaccine strain stimulates cell-mediated immunological mechanisms (as demonstrated in mice) and antibody formation in chickens against Salmonella Enteritidis and Salmonella Typhimurium. The antibody formation does not affect serological testing for Salmonella Gallinarum (rapid serum agglutination).

The vaccine strain is resistant to sulfamerazine. The strain has been demonstrated as genetically stable.
