The Centers for Disease Control and Prevention (CDC) recently revised its definition of vaccine and immunization on one of its web pages, saying the new definition is “more transparent” and cannot be misinterpreted.
“Although there have been slight wording changes over time of the definition of ‘vaccine’ on the CDC website, these have not had an impact on the overall definition,” he said. a CDC spokesperson told The Epoch Times via email.
«The previous definition at Immunization Basics | The CDC could be interpreted to mean that vaccines are 100% effective, which has never been the case with any vaccine. The current definition is therefore more transparent and also describes the ways in which vaccines can be administered. “
Between 2015 and August 31, 2021, a vaccine was defined as “a product that stimulates a person’s immune system to produce immunity against a specific disease, protecting the person against that disease” and vaccination was “the act of ‘introduce a vaccine into the body to produce immunity against a specific disease.
Earlier versions of a vaccine definition also included “immunity” in its definition.
The new definition of vaccine now reads: “a preparation which is used to stimulate the body’s immune response against disease”, whereas vaccination is “the act of introducing a vaccine into the body to produce protection against a specific disease “.
Proponents of the CDC review say it’s natural to revise the definition as science evolves, but opponents say the changes have nothing to do with the evolution of science. Instead, the CDC is conducting the review in response to the fact that current COVID-19 vaccines are less effective against the Delta variant.
Emmy Award-winning investigative reporter Sharyl Attkisson said the new definition was designed to “address the declining capacity of some of today’s’ vaccines”, including the COVID-19 vaccine “, adding that” after the introduction of COVID-19 vaccines, and it was discovered that they do not necessarily “prevent disease” or “provide immunity,” the CDC again changed the definition of vaccines to to say that they are only “producing protection”.
Rep. Thomas Massie (R-Ky.) Took to Twitter about the CDC’s change of definition and compared it to that of George Orwell in 1984, writing, “They’ve been busy in the Ministry of Truth.

The CDC did not respond to a request for comment at press time.
The effectiveness of vaccines in keeping people out of hospital has dropped from 75 to 95 percent, according to the CDC on Aug. 30. The health agency said the largest drop occurred in the most vulnerable group, people over 75. However, vaccines are still effective against serious illnesses.
Several studies find that the effectiveness of COVID-19 vaccines decreases. An ongoing study in the United States has found that the effectiveness of the COVID-19 vaccine increased from 91% to 66% after the Delta variant became dominant in the country. Another study indicated that breakthrough infections increased to 25% of all infections in Los Angeles County between May 1 and July 25.
Israel, with the world’s highest vaccination rates, will administer a fourth dose of Pfizer’s COVID-19 vaccine to its citizens after offering a third booster to people 12 and older in August. The country with a population of more than nine million and with more than 5 million fully vaccinated, is experiencing the fourth wave. More than 2.7 million Israelis received the third dose as of September 8.
The CDC’s updated definition of vaccine and vaccination is the same as in Merriam-Webster, who revised the words earlier this year in February to include messenger RNA vaccines.
As of January 2021, Merriam-Webster still defined a vaccine as “a preparation of killed microorganisms, attenuated living organisms, or fully virulent living organisms which are administered to produce or artificially increase immunity against a particular disease.”
The “old” definition of vaccine can still be found in other online dictionaries, including Oxford Languages.
“It is also important to note that the changes to the definition of ‘vaccine’ do not change the fact that vaccines and the act of immunization have prevented millions of diseases and saved countless lives,” the door said. – speech of the CDC.
