Studies show that almost 100% of cervical cancers are caused by HPV infection. Nearly 600,000 people worldwide are infected with HPV each year, and more than 300,000 of them die from cervical cancer.

There are 4 types of proven vaccine of HPV in the world and they cover different subtypes, which mainly include bivalent HPV vaccine, 4-valent HPV vaccine and 9-valent HPV vaccine. Bivalent HPV vaccine can prevent more than 70% of cervical cancer caused by HPV.   The 4-valent HPV vaccine can prevent 71% of cervical cancer caused by high-risk HPV viruses and about 90% of warts and other diseases caused by low-risk HPV viruses. 9-valent HPV vaccine, with a better protection, can prevent than 90% of cervical cancer.Moreover, various kinds of new vaccines of HPV are researching in the lab till today.
