Ridgeway Biologicals are licensed by the VMD (Veterinary Medicines Directorate) to manufacture autogenous vaccine which are veterinary prescription only medicines. Autogenous vaccines are prepared from a pathogen extracted from a host animal or group which is then used to inoculate the rest of the group. We are able to manufacture autogenous vaccine for many farm animals and fish. For more information on autogenous vaccines please contact your veterinary surgeon.
