Use of the vaccine, use of vaccination, was therefore limited to areas where infected animals had been detected in the past. This was detrimental to the farmers affected, who suffered on two accounts: firstly, because of the disease, and secondly, because of the restrictions.
Vaccino e vaccinazione erano dunque limitati alle zone in cui, in passato erano stati individuati capi infetti, con un duplice danno per gli allevatori colpiti: in primo luogo per la malattia in sé, in secondo luogo per le restrizioni imposte.
