The Centers for Disease Control and Prevention (CDC) altered the definition of “vaccine” because of concern that the definition didn’t apply to COVID-19 vaccines, according to newly released internal emails.
The definition was formerly, “A product that stimulates a person’s immune system to produce immunity to a specific disease, protecting the person from that disease.” That definition now reads, “A preparation that is used to stimulate the body’s immune response against diseases.”
One CDC employee in August, shortly before the definition was changed, said the definition was being used by “right-wing COVID-19 pandemic deniers … to argue that mRNA vaccines are not vaccines,” according to the newly published emails.
