The invention relates to a mutated HPV66 L1 protein (or a variant thereof), a sequence encoding the same, a method for preparing the same, and a virus-like particle comprising the same, wherein the protein (or a variant thereof) and the virus-like particle can induce the generation of neutralizing antibodies against at least two HPV types (e.g. HPV66 and HPV56, or HPV66, HPV56 and HPV53), and therefore can be used to prevent infection by said at least two HPV types, and a disease caused by said infection, such as cervical cancer and condyloma acuminatum. The invention further relates to the use of the protein and the virus-like particle in the manufacture of a pharmaceutical composition or a vaccine for preventing infection by said at least two HPV types, and a disease caused by said infection, such as cervical cancer and condyloma acuminatum.

Mutant of L1 protein of human papillomavirus type 66

The invention relates to a mutated HPV39 L1 protein (or a variant thereof), a sequence encoding the same, a method for preparing the same, and a virus-like particle comprising the same, wherein the protein (or a variant thereof) and the virus-like particle can induce the generation of neutralizing antibodies against at least two HPV types (e.g. HPV39 and HPV68, or HPV39, HPV68 and HPV70), and therefore can be used to prevent infection by said at least two HPV types, and a disease caused by said infection, such as cervical cancer and condyloma acuminatum. The invention further relates to the use of the protein and the virus-like particle in the manufacture of a pharmaceutical composition or a vaccine for preventing infection by said at least two HPV types, and a disease caused by said infection, such as cervical cancer and condyloma acuminatum.

Mutant of L1 protein of human papillomavirus type 39

Disclosed are a mutated HPV11 L1 protein (or a variant thereof), a sequence encoding the same, a method for preparing the same, and a virus-like particle comprising the same, wherein the protein (or a variant thereof) and the virus-like particle can induce the generation of neutralizing antibodies against at least two HPV types (e.g. HPV11 and HPV6), and therefore can be used to prevent infection by said at least two HPV types, and a disease caused by said infection, such as cervical cancer and condyloma acuminatum. Also disclosed is use of the protein and the virus-like particle in the manufacture of a pharmaceutical composition or a vaccine for preventing infection by said at least two HPV types, and a disease caused by said infection, such as cervical cancer and condyloma acuminatum.
