Abstract
The present invention relates to an improved recombinant vaccination vector for the treatment or vaccination against hepatitis B virus (HBV) as well as pharmaceutical compositions or vaccines comprising said recombinant vaccination vector. The present invention also relates to a recombinant vaccination vector for use in a method of vaccination against HBV, as well as kits comprising a vaccine comprising the recombinant vaccination vector.
Claims21
