Abstract
Ross River virus is a mosquito-borne alphavirus which causes several thousand cases of arthritis (epidemic polyarthritis) each year. In this study, binary ethylenimine (BEI) was used to destroy the infectivity of this virus without abolishing the antigenicity or immunogenicity of the virion. Mice immunized intramuscularly with BEI-inactivated virus, with or without Alhydrogel adjuvant, produced antibody which neutralized Ross River virus in vitro, and the mice also failed to develop viraemia when challenged intravenously with live virus. Serum neutralization and in vivo protection were greatest when BEI-inactivated virus was administered without adjuvant.
