During vaccinations by means of live vaccines, chlorine ions present or added to drinking water can harm the live bacteria or viruses which are included in the vaccine and thus impair the vaccine potency.

Synchlor is intended to be added to poultry drinking water during vaccinations. The active ingredient neutralizes the active chlorine ions present in the drinking water and helps preserve the vaccine’s efficiency. The blue color in the product, acts to indicate the presence of Synchlor before adding the vaccine into the drinking water. Chicks blue tongue is an indication for taking the vaccine.
