Component 1 investigations in FMD suspected outbreaks. Component 2 focused on the immune response of vaccinated animals. Component 3 focused on serology as a mean to investigate on the level of FMD virus circulation (anti-NSP antibodies) and on the serotypes present (anti-SP serotype-specific antibodies). GFRA Meeting October
Component 1 (FMD suspected outbreaks – Clinical cases) GFRA Meeting October
COMPONENT 2 (immune response in vaccinated animals) This component has addressed the immune response of vaccinated animals. The outcome to be measured will be the level of antibodies before the vaccine is injected and the level of antibodies after 30 days from the date of vaccination. The animals (Cattle and small ruminants) selected for sampling were ear-tagged and blood samples were collected at the day of vaccination and repeated after 30 days. GFRA Meeting October

Component 2: Immune response in vaccinated animals Sampling and testing criteria Anti-NSP Ab and titration of SP Abs (serotypes O, A, SAT2) before and 30 days PV For each species (goat, sheep, cattle): 150 animals, 6-12 month- old, ear-tagged Possibly, 10 different owners for each species (15 animals for each owner) GFRA Meeting October

Current work Jan 2015 – Jan 2016 Cattle: Collection of serum from unvaccinated animals at the time of injection of the vaccine (time 0) and tag the animals from which the sample has been collected (n=99). Collect serum after 2, 4 and 6 months. Booster vaccination at 6 months for 70 animals. Collect serum again after 2, 4 and 6 months. GFRA Meeting October
