About this listen

VLPs are multi-protein structures, which mimic the organization and conformation of authentic native viruses, but lack the viral genome, and may produce safer and cheaper vaccine candidates. If the specific native viral proteins with immunosuppressive function are excluded from VLPs, the efficacy of these particles can be significantly enhanced. Compared with single protein or peptide, VLPs present more similar conformational epitopes to the original virus. Therefore, antibody reactivity or immune system response is expected to be significantly improved. Due to their highly repetitive surfaces, VLPs are able to induce strong B cell responses without adjuvants by effectively crosslinking specific receptors on B cells. Studies have shown that VLP vaccines can stimulate humoral and cellular immune responses, thus providing effective antiviral protection.
