There's more to the story about the CDC changing the definition of the word vaccine.
Let's start at the beginning.
A vaccine once was,
“Injection of a killed or weakened infectious organism in order to prevent the disease.”

In 2015 it became,
“The act of introducing a vaccine into the body to produce immunity to a specific disease.”

In September 2021, after recent failure was evident, the definition changed to,
“The act of introducing a vaccine into the body to produce protection from a specific disease.”

But the CDC forgot they have a glossary.
Their full current glossary definition is below.
"administered to induce immunity and prevent infectious diseases and their sequelae."
They have also kept this definition:
"Immunization
The process of being made immune or resistant to an infectious disease, typically by the administration of a vaccine. It implies that you have had an immune response."
cdc.gov/vaccines/terms
It is wrong to call a product does not prevent infection a "vaccine".
It dilutes the meaning of the word and destroys public trust in existing vaccine programmes.
