Duration of immunity: 40 days after vaccination.

Revised: February 2025
AN: 03579/2024
Spray-on-chickens with solvent
For the active immunisation of chickens against coccidiosis caused by Eimeria

Onset of immunity: 21 days after vaccination.
Duration of immunity: 10 weeks after vaccination.
None.
Chickens:
Common
(1 to 10 animals / 100 animals
treated):
Intestinal lesion
.
Mild intestinal lesions of e.g. E. acervulina, and E. tenella (lesion scores of +1 or +2 using
the numerical ranking system of Johnson and Reid, 1970), 3 to 4 weeks after
vaccination. Lesions of this severity will not affect the performance of immune chickens.
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 its local representative or the
national competent authority via the national reporting system. See the package
leaflet for respective contact details.
Vaccinate healthy animals only.

Special precautions for use in animals
Do not administer to stressed chicks, e.g. chilled, not feeding or drinking.
For administration by spray on chickens, a red food colouring agent (Cochineal
E120) should be added to the diluted vaccine, or the vaccine should be diluted
using the recommended “Solvent for spray-on-chickens”. For the spray-on-chicken
method of administration a significant reduction in efficacy may be observed if
diluted in tap water without red colourant. The purity of the cochineal E120 must be
in compliance with Commission Directive 95/45/EC.
Chickens should be strictly floor reared on litter. The vaccine contains live coccidia
and is dependent upon replication of the vaccinal lines within the host for
development of protection.
It is common to find oocysts in the gastrointestinal 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 ensures satisfactory flock
protection against all the pathogenic species of contained in the vaccine.
Measures should be taken to ensure that the bulk diluted vaccine is resuspended
at intervals during administration.
Since the protection against coccidial infection following the vaccine administration
is enhanced by natural challenge, it should be noted that access to any therapeutic
agents having anti-coccidial activity at any time following vaccination may reduce
the duration of effective protection. This is important throughout the life of the
chicken.

Revised: February 2025
AN: 03579/2024
To reduce the chance of coccidial field challenge before the onset of immunity,
litter should be removed and chicken housing should be thoroughly cleaned
between rearing cycles.
Ensure that all vaccination equipment is thoroughly cleaned before use.
Special precautions to be taken by the person administering the veterinary
medicinal product to animals
Personal protective equipment consisting of well-fitting masks and eye protection
should be worn when spraying the vaccine.
Special precautions for the protection of the environment:
Not applicable.
Other precautions
Not applicable.
Do not administer anticoccidial agents including sulphonamides and antibacterial
agents before or after vaccination with the veterinary medicinal product.
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
