The present invention relates to nucleic acid molecules that are complementary to both PAP associated domain containing 5 (PAPD5) and PAP associated domain containing 7 (PAPD7), leading to inhibition of the expression of both PAPD5 and PAPD7 when using a single nucleic acid molecule. The invention also provides for PAPD5 and PAPD7 specific nucleic acid molecules for use in treating and/or preventing a HBV infection, in particular a chronic HBV infection. Also comprised in the present invention is a pharmaceutical composition for use in the treatment and/or prevention of a HBV infection.
