    摘要: The present invention refers to a pharmaceutical composition (from hereinafter pharmaceutical composition of the invention), preferably a vaccine composition, comprising a lipid-based nanoparticle and optionally an excipient, wherein the lipid-based nanoparticle comprises the large extracellular loop (LEL) of CD9 of SEQ ID NO 2 displayed on its surface or an amino acid sequence having at least 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 100% identity to SEQ ID NO 2 displayed on its surface. That is, the large extracellular loop (LEL) of CD9 of SEQ ID NO 2, or a sequence having the indicated sequence identity, is associated with or displayed on the exterior surface of the lipid nanoparticle.
