“the Centre for Disease Control and Prevention was seen modifying its definition of the words “vaccine” and “vaccination” on its website.
Before the change, the definition for “vaccination” read, “the act of introducing a vaccine into the body to produce
immunity to a specific disease.” Now, the word “immunity” has been switched to “
protection.”
The term “vaccine” also got a makeover. The CDC’s definition changed from “a product that stimulates a person’s immune system to produce immunity to a specific disease” to the current “a preparation that is used to stimulate the body’s immune response against diseases.”
