It's been documented the CDC has changed the definition of "vaccine" multiple times over the past year.
The Centers for Disease Control (CDC) has carefully "evolved" the definition of vaccination to meet the declining ability of some of today's "vaccines," including the Covid-19 vaccines.
- The original definition, prior to 2015, stated that vaccines "prevent...disease."
- 2015: the definition was altered to say that vaccines "produce immunity," without necessarily preventing disease.
- After the Covid-19 vaccines were introduced, and it was discovered they do not necessarily "prevent disease" or "provide immunity," CDC altered the definition of vaccines again to say that they merely "produce protection."
Do you deny these changes in definition?
