Therefore the antigens that are contained in registered commercial vaccines may loose their current relevance and thereby maybe their protective effect.

In these cases it is important to have a flock specific vaccine produced.

Flock specific vaccines are produced from bacteria that are isolated from livestock of a defined flock. These bacteria are characterised and afterwards multiplied in huge numbers in pure cultures.
The harvested raw antigen is processed in further production steps including the incorporation of additives.
So called adjuvants are added to the vaccines in order to stimulate the immune reaction.
Our standard is to use aluminium hydroxide for aqueous vaccines, Incomplete Freunds Adjuvant for water-in-oil-vaccines and commercial oil-in-water-adjuvants.
Flock specific vaccines are always inactivated, which means the antigens are not able to multiply. Usually they need to be applied parenterally, by injection of every single animal.
Flock specific vaccines can also be administered as aerosol (i.e. as spray) or orally (i.e. through the drinking water).
Concerning commercial fish, the vaccines are also called pond-specific or water intake specific and are administered per injection as well as “per immersionem” which means as a bath.

Please take the delivery times into consideration when ordering flock specific vaccines! |
|
Since flock specific vaccines are produced for an individual flock according to your order, a time span of 4-6 weeks between ordering and delivery of the vaccine is needed. Within this time, the bacterial isolates are characterised, the antigen is being multiplied and the required quality control according to the European Pharmacopoeia (EP) is being conducted after completing the vaccine production.
