Dear Friends, try to understand?
Data of FMD outbreaks in India Processed by National Institute Veterinary Epidemiology and Disease Informatics in attached photo is self-explanatory to reveal the efficacy of FMD CP, either increase or no change in the status of disease in FMD CP areas are the characteristics. After every year of increased occurrence of a disease, next year outbreaks are low due to immunity offered by the disease that is why outbreaks were less in 2015 and in 2016, you can witness the FMD outbreak rampant in all parts of Northern India.
may the efficacy of the vaccines not enough or may presence of a new serotypes not included in the available vaccines
Probably vaccination is compulsory but identification of vaccinated animals is not. Therefore the efficiency of vaccination of wild ruminants and ...so called Holly cows is questionable
may the efficacy of the vaccines not enough or may presence of a new serotypes not included in the available vaccines
We have the same problem in Iran despite of accurate vaccination. Recent outbreak led to high mortality and losses. May be a new strain is circulating in the area.
Dear Alireza, What vaccine you are using? In India after so many molecular and sequencing studies scientists were not able to prove that the outbreak strain(s) were significantly different from those used in the vaccine, here in India, the quality of vaccine is a big question.
Sir,
I feel the efficacy of vaccine use to questionable. Many of the times proper cold chain is not maintained. Identification of vaccinated animals is also not practiced under field conditions many of the times.
Sir,
I feel there is partial failure of the vaccines. Please asses the efficacy of the vaccines.
FMD control is an extremely complex problem. See:

Vaccination is employed as a preventive measure and not curative, as such in endemic areas/country, is needful looking at the virulent nature of the virus. Not all herds may be covered during the period as scheduled may be as a result of conflict, as such, herds not covered might serve as risk factors and as well spreading the virus. please, consider the epidemiology of the virus, as such, needful considering economic aspect.
Key problem is always the compatibility of the field and vaccine virus strains !

Control and territorial eradication of the FMD is an extremely difficult task where the vaccination has an important role within a very complex of measures depending on many factors. It is recommended to study anti-FMD experience of successful countries, I would like to recommend e.g. my paper "Methods of FMF eradication in a country with intensive large scale farming" (see http://vaclavkouba.byl.cz/FMDeradica.htm). One of the key factors is represented by well trained animal health personel (using practical simulation exercises). My methodology is described in "Practical field simulation exercises - basic training form of the preparedness against FMD"(see http://vaclavkouba.byl.cz/simulation.htm).
Your paper nd experience is valuable but you need the honest implementers & honestly good quality vaccines, we are in dearth of that in India.
