Dear colleagues,

 

I would like to give a quick comment on the value of sero-monitoring

In the majority of our countries animal health surveillance system is based on what I call “opportunistic surveillance system”, whereby we wait for a livestock producer or livestock filed officer to report on an outbreak of a given disease. So what would be the value of  sero-monitoring in such a situation? On the other hand vaccination campaigns are rarely done as per the standard prescriptions, greatly jeopardizing the value of either pre or post monitoring vaccination. To me the most practical approach would be “scouting” for the disease, vaccinate the surrounding population at risk least twice on the yearly basis as per the standard prescriptions … and move forward!

 

Dr. Mtui could you comment whether sero-monitoring was ever useful in the just collapsed CBPP rollback plan in Tanzania?

Dear all
I support John
Sero-monitoring is important and this need to be combined with clinical surveillance have a good case definition in place. The monitoring need be to targeted and results have to be released timely for improving efficiency of future campaigns

Dear All

I disagree with Paul and would suggest seromonitoring proved very enlightening in some countries. I realise it is expensive but perhaps in future campaigns we will use a more focused approach, not the blanket vaccination employed in the early stages of PARC, PACE and GREP, in which case seromonitoring is essential to monitor the performance of the vaccination teams and the cold-chain. Otherwise you could be living in a fools paradise erroneously believing  the animals are immune. In Tanzania seromonitoring identified a number of issues which, once identified, were easily rectified. Seromonitoring may not be needed throughout the vaccination campaign but really useful in the early stages to ensure all teams are operating optimally. As Paul mentioned this also gives the Laboratories a chance to gain expertise and ensure all assays are working optimally

Dear Colleagues,

 

Although mentioned once or twice in passing we haven't heard much about seromonitoring during the conference.

 

As some participants know I am not greatly in favour of seromonitoring as a general follow-up to vaccination campaigns.  It is expensive, the results usually arrive too late to be of use, and when they do arrive in time there are insufficient resources for a re-vaccination.  I know it has an important role in disease investigation where vaccine failure is a possibility and is obviously needed for epidemiological studies but as a routine accompaniment  to vaccination.....mmm?  In rinderpest eradication we did a lot of sero-monitoring but I reckon that the most useful thing to come out of it was to train the laboratories to high levels of competence for the much more important sero-surveillance when vaccination ceased.   Money saved on seromonitoring can be used for extra epidemiology such as disease search etc.

 

Would anyone care to put me right on this?

regards,- Moderator.
