Summary for the public


What is Nobilis IB 4-91?

Nobilis IB 4-91 is a lyophilised (freeze dried) vaccine pellet which is made into a solution for dosing.

Nobilis IB 4-91 contains the live attenuated (altered so that it does not cause the disease) avian Infectious Bronchitis Virus (IBV).


What is Nobilis IB 4-91 used for?

Nobilis IB 4-91 is used to immunise chickens to reduce the respiratory signs of Infectious Bronchitis caused by the variant strain IB 4-91, which causes infectious bronchitis in chickens.

Nobilis IB 4-91 can be given to 1-day-old chicks and older chickens by coarse spray or by intranasal (breathed in through the nose) or ocular (absorbed by the eyes) administration. The vaccine can be given to 7-day and older chickens in their drinking water. For long-lasting immunity, chickens should be revaccinated every 6 weeks.


How does Nobilis IB 4-91 work?

Nobilis IB 4-91 contains the live IBV virus that has been attenuated (altered) so that it does not cause the disease. When the chickens are exposed to this attenuated virus, this small exposure helps the chickens’ immune systems to recognise and attack the IBV virus. When exposed to IBV later in life, the chickens will either not become infected or have a much less serious infection.


How has the effectiveness of Nobilis IB 4-91 been studied?

The Nobilis IB 4-91 vaccine has been studied in various vaccination schedules in a number of trials The vaccine was given by coarse spray to chicken of various ages. The main measures of effectiveness included the development of antibodies to the IB 4-91 virus, the overall death rate of the chickens and the percentage of chicken rejected because of disease.. Nobilis IB 4-91 vaccine has also been compared with controls, i.e. chickens that were not vaccinated.


What benefit has Nobilis IB 4-91 shown during the studies?

There was a clear immune response to Nobilis IB 4-91. In one trial, after three weeks 100% of chickens had developed antibodies to the IB 4-91 virus compared with 17% for the controls.


What are the side effects of Nobilis IB 4-91?

Nobilis IB 4-91 can cause mild respiratory signs of disease which may last for a few days depending on the health and condition of the chickens.


What are the precautions for the person who gives the medicine or comes into contact with the animal?

There are no precautions for the person, but it is recommended that they wash and disinfect hands and equipment after vaccinating to avoid spread of the virus.


Why has Nobilis IB 4-91 been approved?

The Committee for Medicinal Products for Veterinary Use (CVMP) agreed that the benefits of Nobilis IB 4-91 are greater than any risks to immunise chickens to reduce the respiratory signs of infectious bronchitis caused by the variant strain IB 4-91. They recommended that Nobilis IB 4-91 should be given a marketing authorisation. The benefit-risk balance may be found in module 6 of this EPAR.

QUALITATIVE AND QUANTITATIVE COMPOSITION
Each vial contains per dose:
Active substance
Live attenuated avian Infectious Bronchitis Virus (IBV) variant strain 4-91:
3.6 log 10 EID 50 *
* EID 50 = 50% Embryo infective dose: the virus titre required to produce infection in 50% of the
embryos inoculated.
For a full list of excipients, see section 6.1
3.
PHARMACEUTICAL FORM
Lyophilisate for suspension.
4.
CLINICAL PARTICULARS
4.1 Target species
Chickens
4.2 Indications for use, specifying the target species
Active immunisation of chickens to reduce the respiratory signs of Infectious Bronchitis caused by the
variant strain IB 4-91.
4.3 Contraindications
Future layers and breeders should not be vaccinated before 3 weeks of age.
Nobilis IB 4-91 given at day-old can adversely affect the efficacy of Turkey Rhinotracheitis (TRT)
vaccine given within 7 days; therefore this vaccination scheme is contraindicated.
4.4 Special warnings for each target species
The vaccine virus may spread from vaccinated to non-vaccinated chickens and appropriate care should
be taken to separate vaccinated from non-vaccinated.
Wash and disinfect hands and equipment after vaccinating to avoid spread of the virus.
4.5 Special precautions for use
Special precautions for use in animals
Only healthy animals should be vaccinated.
Nobilis IB 4-91 is intended to protect chickens against respiratory signs of disease caused by IBV
variant strain 4-91 only and should not be used as a replacement for other IBV vaccines. The product
should only be used after it has been established that IBV variant strain 4-91 is epidemiologically
2/17
relevant in the area. Care should be taken to avoid the introduction of the variant strain into an area
where it is not present.
Care should be taken to avoid spread of the vaccine virus from vaccinated chickens to pheasants.
Special precautions to be taken by the person administering the veterinary medicinal product to
animals
None.
4.6 Adverse reactions (frequency and seriousness)
Vaccination with Nobilis IB 4-91 may induce mild respiratory signs of disease which may persist for a
few days depending on the health and condition of the chickens.
4.7 Use during pregnancy, lactation or lay
Nobilis IB4-91 has been shown to be safe in layers and breeders during lay.
4.8 Interaction with other medicinal products and other forms of interaction
Nobilis IB 4-91 given at day-old can adversely affect the efficacy of Turkey Rhinotracheitis (TRT)
vaccine given within 7 days.
4.9 Amounts to be administered and administration route
At least 3.6 log 10 EID 50 (1 dose) per animal by either spray vaccination, drinking water or
intranasal/ocular administration. Where the number of chickens is between the standard dosages, the
next higher dosage should be used.
Guideline:
Broiler: The vaccine can be administered to 1-day-old chicks and older chickens by coarse spray or by
intranasal/ocular administration. The vaccine can be administered to 7-day and older chickens by
drinking water. For prolonged immunity, chickens should be revaccinated every 6 weeks after the
initial administration.
Future layers and breeders: The vaccine can be administered to future layers and breeders from three
weeks of age onwards via intranasal/ocular route, coarse spray or drinking water.
Spray method: The vaccine should preferably be dissolved in distilled water or alternatively in cool,
clean water. The appropriate number of vials should be opened under water. The volume of water for
reconstitution should be sufficient to ensure an even distribution when sprayed onto the chickens. This
will vary according to the age of the chickens being vaccinated and the management system, but 250
to 400 ml of water per 1 000 doses is suggested. The vaccine suspension should be spread evenly over
the correct number of chickens, at a distance of 30-40 cm using a coarse spray, preferably when the
chickens are sitting together in dim light. The spray apparatus should be free from sediments,
corrosion and traces of disinfectants and ideally should be used for vaccination purposes only.
Drinking water: The vials should be opened under water. Use cool, clean water to dissolve the
vaccine. For administration of the vaccine, as a general rule, dissolve 1 000 doses in one litre per age
in days up to a maximum volume of 20 litres per 1 000 doses. For heavy breeds, or in hot weather, the
quantity of water may be increased up to 40 litres per 1 000 doses. By adding approximately 2 grams
of skimmed milk powder or 20 ml of liquid skimmed milk per litre of water the virus retains its
activity longer.
Ensure that all the vaccine suspension is consumed within 1-2 hours. The vaccine should be given in
the early morning as this is the main period of water intake or during the cool period on a hot day.
Feed should be available when vaccinating. Water should be withheld before vaccination to make the
chickens thirsty. The length of time of water deprivation is strongly dependent on the climatological
3/17
circumstances. Water withholding should be kept as short as possible with a minimum of half an hour.
A sufficient number of water containers to provide adequate drinking space is essential. These should
be clean and free from traces of detergents and disinfectants.
Turn on mains water when all the vaccine water has been consumed.
Intranasal/ocular administration: Dissolve the vaccine in physiological saline solution or sterile
distilled water (usually 30 ml per 1 000 doses, 75 ml per 2 500 doses) and administer by means of a
standardized dropper. One drop should be applied onto one nostril or one eye. Ensure that the nasal
drop is inhaled before freeing the bird.
Ocular/intranasal administration or coarse spray, give the best responses and these should be the
methods of choice, especially when vaccinating young chickens.
Vaccination programme:
The veterinarian should determine the optimum vaccination schedule according to the local situation.
4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
Ten times the maximum dose was shown to be safe for the target species by all the recommended
routes and methods of administration.
4.11 Withdrawal period
Zero days.

ADVICE ON CORRECT ADMINISTRATION
Since the stability of IBV in suspension may be low due to sensitivity to high temperatures and
impurities, water used for dissolving the freeze-dried vaccine should be cool and of good quality. By
adding skimmed milk to the drinking water the vaccine virus retains its activity longer. Only skimmed
milk should be used, since fat in whole milk may block the automatic drinking systems as well as
reduce vaccine virus efficacy.
