What is a vaccine and why did the definition change?

 Another high official in government has also tested positive for Covid although fully vaccinated with 2 boosters--the Michigan Supreme Court Chief Justice Bridget McCormack.  https://www.detroitnews.com/story/news/local/michigan/2022/04/10/michigan-supreme-court-chief-justice-mccormack-tests-positive-covid/9533602002/  The other we know about is Kamala Harris--fully vaccinated with 2 boosters.  https://apnews.com/article/covid-health-kamala-harris-dadf170fbacfd57922cdf51d59e87cdb   Meanwhile, the vaccines are still "emergency use" although President Trump's "Warp Speed" plan became available in December 2020, even though more people died in 2021 under Biden with all the advances and vaccines than under Trump in 2020.  In order to cover for all the misinformation and silencing of other opinions, the language had to be changed. I noticed the second booster isn't being pushed--my doctor says it's optional and the protection seems to be slight.

Here's how the definition has changed, yet many of us older (than 30) people still think of immunity rather than just less severe disease.  Notice the word "protecting" has disappeared as has "produce immunity."

We Bruces got the Pfizer version in February 2021 with great excitement, relief, and awe at the incredible system our local health systems had established in the such a short time.  It was touted, as I recall, at about 90% or higher, had by fall had dropped to 16%. 

The prior CDC Definitions of Vaccine and Vaccination (August 26, 2021):

Vaccine: A product that stimulates a person’s immune system to produce immunity to a specific disease, protecting the person from that disease. Vaccines are usually administered through needle injections, but can also be administered by mouth or sprayed into the nose.

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

The CDC Definitions of Vaccine and Vaccination since September 1, 2021:

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.

See the complete story to follow how "the right wing" was accused of misinformation for pointing this out, and the e-mail exchange in CDC to get a work around. https://technofog.substack.com/p/cdc-emails-our-definition-of-vaccine?s=r  This is how the "misinformation" and fake news becomes a story about the misinformation and was the cause of conservatives being removed from Twitter.
