SUMMARY The Flury LEP Strain of rabies virus grown in BHK 21 cell monolayers has been used for the preparation of an inactivated vaccine. The vaccine produced good antibody levels in mice, guinea-pigs, dogs and cattle, and can be stored for at least 6 months at 4°C. with only a small loss of potency. The results indicate that the BHK 21 vaccine could be of value in the control of rabies.
