For more coverage, our experience in Sudan is to combine vaccination against PPR with other strategic vaccine. This proved to be effective during the national vaccination campaigns like that against sheep pox which is mandatory in Sudan for the export of live sheep to the middle east
Last year (2013) Sudan exported around 4 million heads of sheep to Saudi

Subject: vaccination coverage
Dear colleagues
i gone through some messages mentioning vaccination coverage. the message of our colleague Prof. Kock identified that outbreak with 80% vaccination coverage according to the ministry census data. as we knew from the rinderpest lesson 80% vaccination coverage is quote good. but the situation mentioned above with big outbreak in 2011 and then in 2013 despite the big coverage of vaccination. i think here we should think about number of factor can limit the efficacy of the vaccination process (supposing that vaccine is a good quality): 1) cold chain can be assessed ether storage or during the transportation to the field and also during the process of the vaccination 2) the operator that giving the vaccine in the field. if these two operations were followed well then we have to think about the vaccine efficiency. to monitor the two operations mentioned we have to implement sero=monitoring survey after each vaccination campaign.
thank you
