1. A recombinant nucleic acid molecule comprising:
a negative strand nucleic acid molecule or a pregenomic RNA (pgRNA) nucleic acid molecule encoding a chemokine, a cytokine, an apoptosis inducing protein, a diphtheria toxin A, a diphtheria toxin A fragment, or any combination thereof, flanked by a first viral transcription recognition signal and a second viral transcription recognition signal, wherein the negative strand nucleic acid molecule or pgRNA nucleic acid molecule is from a virus selected from the group consisting of hepatitis B virus, influenza virus and coronavirus;
a first promoter upstream (5′) of the first viral transcription recognition signal and the 3′ end of the negative strand nucleic acid molecule or pgRNA nucleic acid molecule, and
a second promoter located between the second viral transcription recognition signal and the 5′ end of the negative strand nucleic acid molecule or pgRNA nucleic acid molecule encoding a chemokine, a cytokine, an apoptosis inducing protein, a diphtheria toxin A, a diphtheria toxin A fragment, or any combination thereof,
wherein
(i) the first promoter and the second promoter are oriented in opposite direction and toward each other;
(ii) the second promoter and the second viral transcription recognition signal are upstream (5′) of the 5′ end of the negative strand nucleic acid molecule or pgRNA nucleic acid molecule;
(iii) the first and second viral transcription recognition signals are oriented in the same direction; and
(iv) wherein
a. if the negative strand nucleic acid molecule or pgRNA nucleic acid molecule is from a hepatitis B virus, each of the first and second viral transcription recognition signals comprises the epsilon recognition signal sequence of SEQ ID NO: 1;
b. if the negative strand nucleic acid molecule or pgRNA nucleic acid molecule is from an influenza virus, the second viral transcription recognition signal comprises the sequence of SEQ ID NO: 22 and the first viral transcription recognition signal comprises the sequence of SEQ ID NO: 23; or
c. if the negative strand nucleic acid molecule or pgRNA nucleic acid molecule is from a coronavirus, each of the first and second viral transcription recognition signals comprises the sequence of SEQ ID NO: 25, SEQ ID NO: 26, SEQ ID NO: 28, or SEQ ID NO: 30.
