Virus-like particle (VLP) vaccines are an innovative class of vaccines that mimic the structure of viruses without containing any viral genetic material. These particles resemble the outer shell of a virus, allowing them to stimulate a strong immune response without the risk of causing disease. VLPs are created by expressing viral proteins in cells, which then assemble into non-infectious particles that resemble the virus. These vaccines are particularly useful for pathogens that are difficult to cultivate or study in traditional vaccine development methods. VLP vaccines have been successfully used in the development of vaccines for HPV (human papillomavirus) and hepatitis B. One of the advantages of VLP vaccines is their ability to generate both a humoral (antibody) and a cellular immune response, offering protection against future infections. This technology is a promising platform for developing vaccines for a wide range of diseases, including cancer and emerging viral infections.
