On August 25, 2021, CDC official Alycia Downs wrote an email in which she said, “The definition of vaccine we have posted is problematic, and people are using it to claim the COVID-19 vaccine is not a vaccine based on our own definition.”

The definitions in question were as follows:

Vaccine: refers to a product that triggers immunity.

Vaccination: describes an injection preventing a disease.

As the COVID-19 vaccines were ineffective in preventing the virus causing Covid, people were rightly confused.

Down’s email was recently leaked confirming that the CDC changed the definitions for “vaccine” and “vaccinated”.

The new definitions read:

Vaccine: A preparation that is used to stimulate the body’s immune response against diseases. Vaccines are usually administered through needle injections, but some can be administered by mouth or sprayed into the nose.

Vaccination: The act of introducing a vaccine into the body to produce protection from a specific disease.

The Epoch Times has published all 67 emails detailing the definition change.

The leaked emails reveal understandable questions from concerned citizens:

“Our question is how is the CDC and the rest of the world allowed to call the shot a vaccination when it doesn’t even meet your own definition,” one person wrote to the CDC.

“Is it true that this shot for Covid is not actuallya vaccine per your definition? Does this shot make you immune to the Covid virus? If not, why should | get the shot?” another wrote.

As of now, the CDC is attempting to downplay the vastly different “new” definitions assigned to both vaccine and vaccination.

A CDC spokesperson spoke with The Epoch Times saying the “slight changes in wording” did not alter “the overall definition,” of “vaccine,” clarifying “the previous definition at Immunization Basics | CDC could be interpreted to mean that vaccines were 100% effective, which has never been the case for any vaccine, so the current definition is more transparent, and also describes the ways in which vaccines can be administered.”


The CDC has largely ignored the efficacy issue of the c-19 vaccine leaving doctors frustrated with the contradiction of advancing a vaccine known to be ineffective.

The concern over the harmful side-effects is also far reaching.
