DEFRA announced in December that zoos in England would be allowed to vaccinate birds against avian flu subject to meeting the eligibility criteria.
But Scotland and Wales have decided to not vaccinate birds in their zoos as the current risk level is low.
DEFRA argued that English zoos, when they have gained permission to vaccinate their birds, will be aiding global conservation.
A DEFRA spokesperson said: “DEFRA’s position on vaccination for birds outside zoos remains unchanged. We do not intend to permit the vaccination of birds outside zoos in advance of a disease outbreak or as an immediate disease control response.”
