Marks was writing as he rejected nearly all recommendations from a group of experts that advised the FDA to update the labels for the Pfizer and Moderna COVID-19 vaccines.

Vaccines are traditionally known as drugs that prevent an illness. The U.S. Centers for Disease Control and Prevention (CDC) for years said a vaccine is a product that "produces immunity" while vaccination is an injection of an infectious organism "in order to prevent the disease." The agency changed its definitions after people correctly noted that COVID-19 vaccines do not prevent infection.

The public health/media claim they did not say in 2021 the mRNA shots would end Covid is not the most important of the many lies they tell about the jabs, but it is the most annoying - because it is so easily disproved… pic.twitter.com/eHH8aJEATW

Social media is calling bluff on the Centers for Disease Control and Prevention for 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."
