Immunogenicity and Safety of Co-immunization With Cecolin and Hecolin

Study on the Immunogenicity and Safety of Co-immunization With Recombinant Human Papillomavirus 16/18 Bivalent Vaccine and Hepatitis E Vaccine

The purpose of this study is to evaluate the immunogenicity and safety of co-immunization with recombinant human papillomavirus bivalent (Types 16,18) vaccine (Escherichia coli) and Hepatitis E vaccine (Escherichia coli)

Study Overview

• Status: Active, not recruiting
• Conditions: Human Papilloma Virus Infection Type 16; Human Papilloma Virus Infection Type 18; Hepatitis E Virus Infection
• Intervention / Treatment: Biological: Cecolin; Biological: Hecolin

Detailed Description

Cecolin is the first Chinese domestic human papillomavirus (HPV) vaccine. Cecolin is designed to protect against HPV types 16 and 18, the most common virus types that lead to cervical cancer. Hecolin is the first prophylactic vaccine against hepatitis E virus (HEV). The purpose of this study is to evaluate the immunogenicity and safety of co-immunization with Cecolin and Hecolin.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
evaluate the concentration of IgG antibodies to HPV-16	Detect the level of IgG antibodies to HPV-16 at 7 month to determine whether group A is non-inferior to group B	At 7 months after first dose
evaluate the concentration of IgG antibodies to HPV-18	Detect the level of IgG antibodies to HPV-18 at 7 month to determine whether group A is non-inferior to group B	At 7 months after first dose
evaluate the concentration of IgG antibodies to HEV	detect the level of IgG antibodies to HEV at 7 month to determine whether group A is non-inferior to group C	At 7 months after first dose

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Local and systematic adverse events/reactions occurred within 7 days after each vaccination	Adverse reactions associated with vaccine will be observed in subjects after vaccination. To evaluate number of adverse events/reactions compared with non-simultane vaccination group.	During the 7-day period following each vaccination
Adverse events/reactions occurred within 30 days after each vaccination	To evaluate number of adverse events/reactions compared with non-simultane vaccination group.	Within 30 days after any vaccination
Serious adverse events occurred throughout the study	Safety analysis. To evaluate number of SAEs compared with the non-simultane vaccination group	Up to 7 months
