IBR vaccine model aids protection

摘要

A new vaccination approach for infectious bovine rhinotracheitis (IBR) in beef and dairy cattle will not only simplify control, but will also double the length of protection from six to 12 months. The new vaccine programme, put forward by Pfizer Animal Health, suggests combining the use of live and inactivated vaccines for the most effective control. The programme involves giving all naive animals over the age of three months an initial live dose of a marker vaccine (Rispoval IBR Marker Live). This is then followed six months later by a single dose of an inactivated marker vaccine (Rispoval IBR Marker Inactivated), that will then give protection for up to 12 months. An annual booster of the inactivated vaccine will be needed for continued protection.
