Edema Vac F18-E.coli vaccine for pigs is given orally as an aid in the prevention of edema disease caused by F18-positive E. coli. The receptor necessary to allow pigs to be actively vaccinated develops in most pigs between 15 and 20 days of age.
Some herds that experience excess mortality may benefit from a second vaccination to account for this variation. In recent field studies, ARKO's Edema Vac demonstrated efficacy against virulent F-18 E. Coli by decreasing mortality associated with edema disease by nearly 99%.
Vaccine should be administered at 18 days of age or older.
