Koi Carp Vaccine Update


The Board of Henderson Morley plc (“Henderson Morley” or “the Company”), the AIM listed drug discovery company, is pleased to provide the market and its shareholders with an update in respect of the studies relating to the Koi Carp vaccine following the announcement made on 3 October 2006.

These studies were designed to establish if the vaccine candidate is able to boost the immune system of vaccinated fish and included dose ranging studies to determine at what dose the vaccine should be administered. A successful vaccine should enable Koi exposed to virus, to mount a successful immune response against KHV and thus prevent disease. These studies examined antibody responses to vaccination also known as antigenicity studies.

The antigenicity studies of the Koi herpes vaccine candidate have now been completed. The data has been analysed and the Board is pleased to announce that 100% of the vaccine recipients tested have produced a significant immune response.

This level of immunity is a very good indicator of a successful vaccine being developed. Further field studies are ongoing and the Company will keep shareholders informed of progress in due course.
