Dear Paul,
I would like to request for opinion on vaccination in the face of the outbreak of PPR in the herd.
Dr. M. Afzal

In my opinion vaccination of infected and at-risk flocks/herds with good quality PPR vaccine stops transmission very quickly with new clinical cases ceasing after one or two weeks. If PPR vaccine is like RP vaccine (an assumption I know) then it provides protective imunity through non-specific mechanisms like interference within 2-3 days, and detectable specific antibody within 5-6 days (VN tests). More answers please. Moderator.
