Abstract
An isolated polypeptide comprising a substantially antigenic part of at least one hepatitis A virus epitope, the polypeptide being free from infectious material. The polypeptide is the expression product of a DNA molecule which has been incorporated into a virus, preferably vaccinia virus, using recombinant DNA technology. This expression product, of the recombinant virus containing the DNA molecule coding for it, may be incorporated into a vaccine for immunising against hepatitis A virus.
