Abstract An inactivated vaccine against rabies virus was prepared from the attenuated ATCC PV-12 viral rabbit Pasteur strain. The virus was grown on Baby Hamster Kidney (BHK21) cells, and the supernatant was purified by filtration and inactivated with beta-propriolactone. The inactivated product was checked according to the NHI and European Pharmacopoeia methods. Part of the product was then lyophilised and the other part was adjuvanted with Al(OH)3. Both parts were used to vaccinate and boost groups of horses, cattle and sheep at different intervals. Their immunogenicity was compared with a similar commercial product. Blood samples were collected on a regular basis and the antibody titre was determined by the Fluorescence Antibody Virus Neutralisation (FAVN) test. No significant differences were found between species after both inoculations even though the immune response increased in intensity and duration after the booster dose in all the animals tested and was stronger and lasted longer with the adjuvanted aliquot.
