Source: VMD Summary of Product Characteristics (SPC). Last updated 26 Mar 2026.

For active immunisation of chickens in order to reduce the detrimental effect resulting
from the infection by avian infectious bronchitis virus, serotype Massachusetts on the
ciliary activity, which may be manifested in respiratory clinical signs.
Onset of immunity: 3 weeks after vaccination
Duration of immunity: 8 weeks after vaccination
Coarse spray and oculonasal route: from one day of age
Drinking water route: from 7 days of age
1. By spraying

Revised: June 2023
AN: 01938/2022 & 01945/2022
It is recommended to resuspend 1000 doses of the vaccine in 150 - 300 ml of distilled
water. The number of doses diluted corresponds to the number of birds in a flock.
The volume of water for reconstitution should be sufficient to ensure an even
distribution when sprayed onto the birds, and will vary according to the age of the
birds being vaccinated and the management system.
The reconstituted vaccine suspension should be spread evenly over the correct
number of chickens, at a distance of 30 – 40 cm using a coarse spray (targeted
average droplet size of 150 - 170 microns), 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.
2. Administration in the drinking water
Suspend the vaccine in cool and clean water without traces of chlorine, other
disinfectants or impurities in a number of doses corresponding to the number of birds
to be vaccinated.
Vaccine should be suspended immediately before use.
The volume of water for reconstitution depends on the age of the birds, breeds, the
management practice and weather conditions.
In order to determine the quantity of water in which vaccine will be suspended
for the vaccination of chickens in a younger age category (until third week of life), the
following are guidelines:
-
thousand of chickens in the 7th day of life = 1 x 7 = 7 L)
It is important to dissolve the vaccine in the amount of water which will be drunk
within 1.5 - 2.5 hours (taking into account the different types of drinking systems for
poultry).
In order to make the birds thirsty, withdraw the supply of drinking water up to 2 hours
prior to immunisation (depending on the air temperature).
Always make sure that there is food available when vaccinating. Birds will not drink if
they have no food to eat. The drinking system should be clean, without traces of
chlorine, other disinfectants or impurities.
3. Oculo-nasal administration
Suspend 1000 doses of the vaccine in 100 ml distilled water
A dose of reconstituted vaccine is 0.1 ml, i.e. two drops, irrespective of poultry age,
weight and type. Instil one drop into the eye and one drop into the nose opening.
For chickens aged from 1 to 14 days of smaller breeds, 4 drops of 25 μl should be
used. Administer one drop in each eye (0.05 ml altogether) and then one drop in
each nostril (0.05 ml altogether).
None.
Transient respiratory disturbances, including tracheal rales have been observed very
commonly for 3-10 days post vaccination. These did resolve spontaneously and did
not need treatment.
The frequency of adverse reactions is defined using the following convention:
- very common (more than 1 in 10 animals treated displaying adverse reactions)
- 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
Special precautions for use in animals
All the birds in the flock should be vaccinated at the same time.
The vaccine strain can spread to susceptible, unvaccinated chickens for a minimum
of 10 days following vaccination. It is possible that the vaccine virus can be spread to
non-target susceptible species. Appropriate veterinary and husbandry measures
should be taken to avoid spread of the vaccine strain to unvaccinated birds or
susceptible species as much as possible.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
Care should be taken when reconstituting and administering the vaccine . Wash and
disinfect hands and equipment after administration of the vaccine. When spraying the
vaccine, personal protective equipment consisting of masks with eye protection should
be worn by the operator and staff.
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.
Store and transport refrigerated (2 C – 8 C).
Protect from light.
Do not freeze.
Zero days.
