Since the outbreak of COVID-19, humanity has made great strides in developing vaccines. Scientists have developed highly effective vaccines in a very short period of time, and in addition to being able to fight the new crown virus, they have also advanced the development of the entire industry in an unprecedented way.
When it comes to vaccine development, the mRNA vaccine is one of the most transformative inventions of recent years. mRNA is messenger RNA, and the emergence of such vaccines has changed the human understanding of human immunity.
Traditional viral vaccines generate an immune response in the recipient through inactivated fragments of viral lysis. But the beauty of mRNA vaccines is that they are able to pass on genetic instructions directly to cells and tell them how to make the specific proteins needed for an immune response. mRNA helps cells build, maintain, and repair substances in the human body through proteins.
But mRNA vaccines also have a limited "teaching" effect on the immune system, as they only teach the immune system to respond specifically to specific viruses. A vaccine that scientists are working on can teach the immune system to respond to any cell that looks like a flu virus, even if it has never been encountered.
This way, people don't have to wait for T cells and B cells in the adaptive immune system to learn how to detect and fight viruses. The vaccine is capable of triggering epigenetic changes in the inherent response of cells, equivalent to directly directly to the immune system to kill the virus immediately. In short, this vaccine strengthens the innate immune response through epigenetic imprinting, thereby breaking all viruses.
