Abstract: Provided are lipid particles encapsulating a nucleic acid capable of expressing an E6 antigen and an E7 antigen of human papillomavirus, whereby a vaccine for preventing and/or treating infection with human papillomavirus type 6 and/or type 11 can be provided. The lipid particles comprise a lipid that is a cationic lipid having the general formula (Ia), or a pharmaceutically acceptable salt thereof. [In the formula, R1, R2, p, L1 and L2 are as defined in the specification.

Abstract: Provided is a vaccine for preventing and/or treating infection with human T-cell leukemia virus type 1 (HTLV-1). A lipid particle encapsulating a nucleic acid expressing a gp46 antigen or a Tax antigen of human T-cell leukemia virus type 1 (HTLV-1), wherein the lipid comprises a cationic lipid represented by general formula (Ia): or a pharmaceutically acceptable salt thereof, wherein R1 and R2 each independently represent a C1-C3 alkyl group; L1 represents a C17-C19 alkenyl group optionally having one or more C2-C4 alkanoyloxy groups; L2 represents a C10-C19 alkyl group optionally having one or more C2-C4 alkanoyloxy groups, or a C10-C19 alkenyl group optionally having one or more C2-C4 alkanoyloxy groups; and p is 3 or 4.

Abstract: The present invention provides a vaccine for preventing and/or treating infections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The present invention relates to a lipid particle encapsulating a nucleic acid molecule capable of expressing the S protein and/or a fragment thereof of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), wherein the lipid comprises a cationic lipid represented by general formula (Ia) or a pharmaceutically acceptable salt thereof: wherein R1 and R2 each independently represent a C1-C3 alkyl group; L1 represents a C17-C19 alkenyl group which may have one or a plurality of C2-C4 alkanoyloxy groups; L2 represents a C10-C19 alkyl group which may have one or a plurality of C2-C4 alkanoyloxy groups or a C10-C19 alkenyl group which may have one or a plurality of C2-C4 alkanoyloxy groups; and p is 3 or 4.
