“…a product that stimulates a person’s immune system to produce immunity to a specific disease, protecting the person from that disease.” Immunity, in turn, is defined as “Protection from an infectious disease,” meaning that “If you are immune to a disease, you can be exposed to it without becoming infected.” Neither Moderna nor Pfizer claim this to be the case for their COVID-19 “vaccines.”
