Abstract: A method of treating livestock with a vaccine includes mixing a reducing agent, such as sodium thiosulfate, with water, which may include oxidizing water sanitizers, mixing the vaccine with the water after the reducing agent has neutralized the water sanitizers, and treating the livestock with the vaccine and water mixture. The method may include adding a buffer to the water along with the reducing agent to adjust the pH, and adding a coloring agent to the water to aid in identifying livestock that has been treated with the vaccine. The vaccine may be administered to the livestock in different ways, such as by including it in drinking water or by spraying the livestock with the vaccine and water mixture.

Abstract: A vaccine stabilizer for adjusting water quality that adversely effects the life of a vaccine to be administered to livestock. The stabilizer is composed of a reducing agent to neutralize oxidizing water sanitizers of at least about 0.0002 percent by weight and a coloring agent to provide a visual reference for aiding in determining the administration of the vaccine to the livestock of from about 0.00 to about 99.9998 percent by weight.
