There had already been a gap in supply of the vaccine between June and August due to a batch being out of specification.
The company says it submitted an Out of Specification request to release the vaccine but was unsuccessful.
The next delivery of vaccine was expected at the end of August, however this has unfortunately been delayed until October, and there is no certainty of this delivery.
Ceva says it deeply regrets the inconvenience caused to sheep farmers this year.
Roy Geary, Vice President for Northern Europe (including the UK) at Ceva Animal Health, said: “The manufacturing of vaccines is a complex process that involves stringent quality control measures and adherence to regulatory guidelines.
"There have been unforeseen manufacturing issues at our production facilities, which have temporarily affected the ability to meet the demands of the UK sheep market within the main seasonal vaccination period for EAE.
"As a responsible provider, we are actively addressing these issues to minimise the impact on customers.”
“We are recommending that vets and farmers follow the advice published on 24th July 2024 from the Sheep Vet Society and Sheep Antibiotic Guardian Group (SAGG).”
