The oral vaccine stabilizer produced by ARKO Laboratories is a combination of proteins, chemicals, sugars and buffer that will protect live organisms when they are used as oral vaccines delivered through a watering system. The stabilizer will neutralize residual chlorine that may be present in the water line. It will maintain vaccines in a live state in the water lines for at least a six hour time period at a level necessary to induce a vaccine response in the target animals. Research at ARKO indicates that vaccines in plain, non stabilized water may lose much of their potency in the first hour or two of administration. This is not long enough to allow for vaccination of a large group of animals.
