Summary
Expression of the entire open reading frame of hepatitis A virus was achieved in a vaccinia virus/T7/EMCV hybrid system. The expressed antigens were characterized as particles with buoyant densities and sedimentation coefficients typical of emtpy capsids and pentamers of HAV. This was further confirmed by electron microscopy. All capsid proteins were determined as components of the particles which raised neutralizing antibodies in an immunized rabbit.
