The vaccine strain is a deletion mutant with a limited growth potential in mammalian tissue. It is able to multiply locally at the submucosal injection site during a short period and is shed into the oro-nasal cavity during a few days, but the vaccine strain does not survive on the oro-nasal mucosa and does not disseminate systemically at the recommended dose.
