Cecolin® HPV Vaccine
The bivalent Cecolin® HPV Vaccine protects people against HPV 16 and 18, two major Human Papillomavirus (HPV) types causing about 70 percent of all cervical cancers, the third most common cancer among women. The Escherichia coli-produced bivalent Cecolin HPV vaccine was jointly developed by Innovax, a biotechnology company based in Xiamen, Fujian province, China, in cooperation with Xiamen University.
Cecolin was approved by the National Medical Products Administration of China on December 30, 2019, and officially launched in China (excluding Hong Kong, Macao, and Taiwan) in May 2020. It is the first domestically manufactured HPV vaccine against cervical cancer in China. The World Health Organization (WHO) found the vaccine safe and prequalified it for use in 2021. On March 12, 2023, The Lancet Regional Health Western Pacific published results from a phase 1 study that concluded that the candidate E. coli-produced 9vHPV vaccine had been preliminarily proven well tolerated and immunogenic.
Cecolin has been licensed in Bangladesh, Morocco, Nepal, Thailand, the Democratic Republic of the Congo, and Cambodia by March 2023.
Xiamen Innovax Biotech Co., Ltd. is a leading company in developing, manufacturing, and marketing innovative vaccines, with its headquarters and manufacturing based in Xiamen, China.
Cecolin 9 Vaccine Vs Gardasil9 Vaccine
The Lancet Infectious Disease published results from a clinical study in July 2023 that compare the immunogenicity of the E coli-produced HPV 9-valent vaccine Cecolin 9 with Gardasil9. Study Interpretation: Cecolin 9 induced non-inferior HPV type-specific immune responses compared with Gardasil9. Data on the first-in-human phase 1 clinical trial of Cecolin 9 have been published, which preliminarily reveal its safety and immunogenicity in healthy adults, and the results from its phase 2 clinical trial are in preparation.
According to The Lancet Global Health in 2020, the vaccine Cecolin is priced at ¥329 ($47.7) per dose.
Cecolin is a vaccine indicated for women 9 through 45 years of age to prevent the following diseases caused by two HPV types included in the vaccine. Cervical, vulvar, vaginal, and anal cancer are caused by HPV types 16 and 18. According to the Centers for Disease Control (CDC), HPV is linked to more than 90% of anal and cervical cancer cases, nearly 70% of vaginal cancer cases, and more than 60% of penile malignancy cases .
Cecolin vaccination requires three intramuscular injections over six months (0,1 and 6). In the phase 3 study, the dosage contained 40μg HPV 16 virus-like particle antigen and 20μg HPV 18 virus-like particle antigen adsorbed in alum-adjuvant.
May 2023 - Safety and immunogenicity of an Escherichia coli-produced 9-valent human papillomavirus L1 virus-like particle vaccine (types 6/11/16/18/31/33/45/52/58) in healthy adults: an open-label, dose-escalation phase 1 clinical trial. Study Interpretation - The candidate E. coli-produced 9vHPV vaccine has been preliminarily proven well tolerated and immunogenic, encouraging further studies in large cohorts with a broader age range.
August 26, 2022 - The Lancet Infectious Disease published results after 66 months of phase 3 clinical study. Interpretation of results: The E coli-produced HPV 16 and 18 vaccine was well tolerated and highly efficacious against HPV 16 and 18 associated high-grade genital lesions and persistent infection and would supplement the global HPV vaccine availability and accessibility for cervical cancer prevention.
October 14, 2021 - Xiamen Innovax Biotech Co., Ltd. received an official letter from the World Health Organization (WHO) confirming that WHO has accepted its bivalent human papillomavirus vaccine Cecolin® for Prequalification.

Cecolin Clinical Trial
Clinical Trial NCT01735006: Efficacy and Immunogenicity Study of Recombinant Human Papillomavirus Bivalent（Type 16/18) Vaccine. The efficacy, safety, and immunogenicity results from the pivotal phase 3 clinical trial were conducted on 7,372 healthy women in 5 provinces in China. In preventing precancerous lesions and persistent HPV infection, these two key indicators of effectiveness are that the corresponding protection rate for high-grade precancerous lesions is 100%. The protection rate for persistent HPV infection is 97.8%. Regarding vaccine safety and preventive effect indicators, the effectiveness of domestic vaccines is comparable to that of imported vaccines at an internationally advanced level.
