The Centers for Disease Control and Prevention (CDC) recently revised its definition for vaccine and vaccination on one of its web pages, saying that the new definition is “more transparent” and can’t be misinterpreted.

“While there have been slight changes in wording over time to the definition of ‘vaccine’ on CDC’s website, those haven’t impacted the overall definition,” a CDC spokesperson told The Epoch Times via email.
