There are currently several vaccines that use mRNA technology, including the COVID-19 vaccines developed by Moderna and Pfizer-BioNTech. These vaccines work by introducing a small piece of genetic material called mRNA into the body. The mRNA codes for a specific protein, such as the spike protein found on the surface of the SARS-CoV-2 virus, which causes COVID-19. Once inside the body, the mRNA is translated into the protein, which stimulates an immune response. The immune system then produces antibodies to the protein, which can protect against future infection with the virus.
There are also several other vaccines that are currently in development that use mRNA technology, including vaccines for influenza, cytomegalovirus, and rabies, among others. mRNA technology has the potential to revolutionize the way we develop vaccines, as it allows for the rapid development and production of vaccines for new diseases.
