Vaxxon SRP Klebsiella from Vaxxinova US is a vaccine licensed by the USDA for the management of mastitis caused by Klebsiella pneumoniae spp. This vaccine was formerly known as KLEBVax SRP.
Dairy losses due to Klebsiella-induced mastitis are expensive. However, recent field trials report reductions in cases of Klebsiella-induced mastitis, with some herds nearing 100% reduction, where Vaxxon SRP Klebsiella has been introduced.
