'''In Endemic Areas''' disease cannot be prevented by slaughter due to large numbers of carrier stock. Annual '''inactivated whole virus vaccination''' using local subtypes is used. This vaccine is inactivated by azuridines, using alhydrogel adjuvant for cows, and oil for pigs. Subunit vaccines are ineffective. The course involves 2 initial injections at 4 months (if dams are vaccinated), followed by boosters every 6-12 months, which induces virus-neutralizing antibodies. Vaccination DOES NOT render meat harmful to consumers, but does affect when it can be exported.
