CDC Quietly Changes Definition of “Fully Vaccinated”

Despite CDC Director Rochelle Walensky’s assurances that changing the definition of fully vaccinated on the part of her agency was not under consideration, if Anthony Fauci’s remarks earlier this month were any indication, it was only a matter of time before the change would take place. Around the middle of December even Fauci said changing the definition of vaccinated was not being discussed. Sure enough it happened a few days ago:

“For people who are unvaccinated or are more than six months out from their second mRNA dose (or more than 2 months after the J&J vaccine) and not yet boosted, CDC now recommends quarantine for 5 days followed by strict mask use for an additional 5 days. Alternatively, if a 5-day quarantine is not feasible, it is imperative that an exposed person wear a well-fitting mask at all times when around others for 10 days after exposure. Individuals who have received their booster shot do not need to quarantine following an exposure, but should wear a mask for 10 days after the exposure.”

What it comes down to is, according to the CDC’s new recommendations, if you are vaccinated but did not get booster shots, you must take the same level of precaution as someone who has not been immunized.

What is concerning is that experts recently weighed in with Israel considering a 4th booster shot stating that there comes a point when the body can suffer from vaccine fatigue. A person who is unvaccinated and gets coronavirus has a variety of almost 30 antibodies to different parts of the virus. If a person who recovers from COVID-19 and gets vaccinated, the vaccine emphasizes a specific antibody that the shot is designed to produce while other antibodies are de-emphasized in the body.

The vaccines and booster shots contain the same spike protein in which it is a version of the original coronavirus that is now gone. With a British study cited by The New York Times stating that booster shots are less effective against Omicron, a person’s ability to fight off COVID-19 is seriously compromised especially if they get additional shots.

With Biden’s vaccine mandates being challenged in court and this policy change, the legal conflict comes down to what the definition of vaccinated is. One doctor on Twitter stated that the definition made by the CDC of fully vaccinated was political, and not medical. Unfortunately, that will be of little reassurance to people who’s jobs and livelihoods are at risk because of the CDC’s rules and if Biden’s vaccine mandate is upheld by the Supreme Court.

    Political history rhymes.
    On 15 June 1961, GDR [East German] head of state Walter Ulbricht said:
    “Nobody has the intention of building a wall.”
    Ulbricht’s response was surprising because no one had suggested the idea of an actual wall before.
    Two months later, construction work on the Berlin barrier began.
