Clinical Study of HPV Therapeutic DNA Vaccine (NWRD08) in Patients With Cervical HPV16 and/or HPV18 Positive

This is an open-label exploratory clinical study. The main objective is to explore the immunogenicity of HPV therapeutic DNA vaccine NWRD08.

The main objective is to explore the immunogenicity of HPV therapeutic DNA vaccine NWRD08.The secondary objective was to observe the safety of NWRD08 in cervical patients who were positive for HPV16 and/or HPV18, and to initially explore the efficacy of NWRD08.
