Saudi Arabia and A G-VII
Outbreaks have been reported on large scale dairy farms, confirmed as
serotype A G-VII
Farms using regular vaccination with aqueous based, NSP purified,
≥6.0PD50 vaccine
Contains A Iran 05 and A Saudi 95 strains as part of a polyvalent vaccine
Vaccination schedule
– Primary course 3, 4, 5 and 6 months of age
– Booster every 90 days thereafter
16. OS16
• Rapidly changing situation – very dynamic
• Collection of samples from field outbreaks is vital
• Important to continue to exchange epidemiological data and laboratory results
• Vaccine recommendations require careful consideration
• Apparent gap in vaccine coverage
• WRLFMD is collating lab and field data regarding the performance of vaccine
against this strain
• Greater confidence in the use of vaccines urgently required – from in vivo
potency tests or data from the field (vaccine efficacy).
Summary and priorities
17. OS16
• Fuat Özyörük, Alexei Mischenko, Alexei Scherbakov, Jitendra Biswal and
Bramhadev Pattnaik, for providing sequence data.
• Support for the WRLFMD and research projects
• Collaborating FMD Reference Laboratories and field teams
• Partners within the OIE/FAO FMD Lab Network
• Funding by DEFRA
