The plague year of 2020 is likely to be remembered as the time when these traditional vaccines began to be supplanted by genetic vaccines. Instead of injecting a weakened or partial version of the dangerous virus into humans, these new vaccines deliver a gene or piece of genetic coding that will guide human cells to produce, on their own, components of the virus. The goal is for these components to stimulate the patient’s immune system. One method for doing this is by taking a harmless virus and engineering into it a gene that will make the desired component.
