Immunity, according to the CDC website, is “Protection from an infectious disease. If you are immune to a disease, you can be exposed to it without being infected.” They explain that “Immunity to a disease is achieved through the presence of antibodies to that disease in a person’s system.” These antibodies are “disease specific.”
There are two types if immunity, active and passive. “Active immunity results when exposure to a disease organism triggers the immune system to produce antibodies to that disease.” This occurs “through infection with the actual disease, resulting in natural immunity, or introduction of a killed or weakened form of the disease organism through vaccination.”
COVID has added a twist to the vaccine concept by using messenger RNA rather than attenuated virus to create immunity. This is a new approach to “vaccination” and if validated as safe and effective, opens the door to disease prevention on a previously unimaginable scale. But with all new technologies, like self-driving cars, the proof is in the pudding.
