According to data from the World Health Organization (WHO), cervical cancer is one of the most common gynecological tumors worldwide. In China, it ranks as the second most common malignant tumor among women aged 15 to 44.
It is well established that persistent infection with high-risk human papillomavirus (HPV) types is the primary cause of cervical cancer. Among these, seven high-risk HPV types (16, 18, 31, 33, 45, 52, and 58) are responsible for approximately 90% of cervical cancers and 80% of high-grade cervical precancerous lesions worldwide. These same seven HPV types also account for 85%–90% of HPV-related vulvar cancers, 80%–85% of HPV-related vaginal cancers, and 90%–95% of HPV-related anal cancers.
The 2017 WHO position paper states that HPV vaccines should be used as part of a comprehensive, coordinated strategy for the prevention of cervical cancer and other HPV-related diseases.
Merck & Co., Inc. (known as MSD outside the United States and Canada) announced on April 29, 2018, that its nine-valent HPV vaccine had received conditional marketing approval from the National Medical Products Administration (formerly the China Food and Drug Administration). The vaccine is indicated for females aged 16 to 26 years and is administered in a three-dose regimen. According to the approval granted by the National Medical Products Administration, the nine-valent HPV vaccine is indicated for the prevention of cervical cancer caused by HPV types 16, 18, 31, 33, 45, 52, and 58; cervical intraepithelial neoplasia (CIN 1/2/3) and adenocarcinoma in situ (AIS) caused by HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58; and infections caused by HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58.
The HPV vaccine is the first vaccine globally to include cancer as an indication in its package insert. The nine-valent HPV vaccine approved in China is composed of virus-like particles (VLPs) made from the major capsid proteins of HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58, which are highly purified and blended.
