At 31 days after the 2nd vaccination of porcine epidemic diarrhea virus (PEDV) live vaccine the vaccinated sows were shown to have antibody titers of 1: 4 to 1: 128, and the titers were 1: 4 or 1: 8 at six months after vaccination. Maternally derived antibodies in piglets from the vaccinated sows disappeared around 2 months of age.
