Vaxxon SRP® Salmonella

Protect your herd & your profits

Vaxxon SRP® Salmonella (USDA true name Salmonella Newport Bacterial Extract) is fully licensed by the USDA, and was the first USDA licensed vaccine to use SRP® technology. This means the antigen is a blend of purified SRP proteins rather that whole, killed bacterial cells. SRP proteins are necessary for bacterial acquisition of iron, which is critically important for Salmonella to cause disease in cattle. Our SRP protein is extracted from naturally occurring, non-GMO Salmonella. Vaxxon SRP Salmonella is available in the US through major animal health distributors. Available in Canada exclusively through Vetoquinol.

INDICATIONS: This product has been shown to be effective for vaccination of healthy cattle 6 months of age or older against disease caused by Salmonella Newport.  The duration of immunity is unknown.  For more information regarding efficacy and safety, see
