CDC Science Brief: COVID-19 Vaccines and Vaccination

Center for Disease Control ^ | 09/15/2021 | CDC

[Brian Griffin]

Vaccine efficacy refers to how well a vaccine performs in a carefully controlled clinical trial, and effectiveness describes its performance in real-world observational studies. Evidence demonstrates that the approved or authorized COVID-19 vaccines are both efficacious and effective against symptomatic, laboratory-confirmed COVID-19, including severe forms of the disease. In addition, as shown below, a growing body of evidence suggests that COVID-19 vaccines also reduce asymptomatic infection and transmission.

Rhesus macaque challenge studies provided the first evidence of the potential protective effects of Pfizer-BioNTech, Moderna, and Janssen COVID-19 vaccines against SARS-CoV-2 infection, including both symptomatic and asymptomatic infection. Vaccinated macaques developed neutralizing antibodies that exceeded those in human convalescent sera and showed no or minimal signs of clinical disease after SARS-CoV-2 challenge. In addition, COVID-19 vaccination prevented or limited viral replication in the upper and lower respiratory tracts, which may have implications for transmission of the virus among humans

There is now a substantial volume of scientific literature examining the effectiveness of COVID-19 vaccination against SARS-CoV-2 infection, symptomatic disease, and other clinical outcomes; detailed summaries of these studies are available in the International Vaccine Access Center’s VIEW-Hub resource library[https://view-hub.org/resources].

Studies from the United Kingdom have noted effectiveness of the Pfizer-BioNTech vaccine against confirmed infection (79%) and symptomatic infection (88%)

Notably, in the United Kingdom, Canada, Qatar, South Africa, and Israel, vaccine effectiveness against hospitalization related to Delta was >90%

The United Kingdom and Canada used prolonged intervals of 12–16 weeks between vaccine doses, which have been observed to induce higher immunogenicity and effectiveness.

Table 1a. Effectiveness of COVID-19 Vaccination Against SARS-CoV-2 Infection and Symptomatic Disease (Including Severe Disease and Hospitalization) Caused by the Delta Variant

United States Healthcare workers, first responders, and other essential and frontline workers Pfizer-BioNTech, Moderna, or Janssen SARS-CoV-2 infection 66%(26%-84%)

United States Health system members ≥12 years Pfizer-BioNTech SARS-CoV-2 infection 75%(71%-78%) Hospitalization 93%(84%-96%)

In addition to preventing morbidity and mortality associated with COVID-19, currently approved or authorized vaccines also demonstrate effectiveness against asymptomatic SARS-CoV-2 infection....

Table 1b. Effectiveness of COVID-19 Vaccination Against Asymptomatic SARS-CoV-2 Infection When Different Variants Predominated

Qatar General population ≥12 years Moderna Delta 80%(54%-93%) Pfizer-BioNTech Delta 36%(11%-54%)

Two studies have observed poor antibody response to the Pfizer-BioNTech vaccine among nursing home residents compared with staff ; one study noted 38% of nursing home residents had undetectable antibodies to the Beta variant at 2–4 weeks after the second dose of Pfizer-BioNTech vaccine, compared with 12% with Moderna vaccine. Another study showed declining antibody levels among nursing home residents, with 72% of residents having undetectable neutralizing antibody levels at 6 months post-vaccination with Pfizer-BioNTech.

A study of U.S. long-term care residents, who were among the first groups in the United States to be vaccinated, found effectiveness of mRNA vaccination against infection declined from 75% in March–May 2021 to 53% in June–July 2021.

For the Delta variant, early data indicate vaccinated and unvaccinated persons infected with Delta have similar levels of viral RNA and culturable virus detected, indicating that some vaccinated people infected with the Delta variant of SARS-CoV-2 may be able to transmit the virus to others. However, other studies have shown a more rapid decline in viral RNA and culturable virus in fully vaccinated people. One study observed that Delta infection in fully vaccinated persons was associated with significantly less transmission to contacts than persons who were unvaccinated or partially vaccinated.

The CDC report itself has links to the original medical journal sources.

I've added some percent signs for clarity.

24/7 we’re surrounded by false CDC propaganda. Even on FR, the CDC plandemic propaganda has to flow - can’t let the public escape the propaganda machine.

Go vax yourself, Biden Bot.

PING!

The words “science” and CDC do not belong in the same sentence.

Okay. They are lying. Their entire premise is false and they use this trash to insist babies and pregnant women 'need' vaccines for a respiratory influenza for which they don't have an accurate test.

This whole thing is a farce. There is no accurate Covid test and sometimes ANthony Fauci admits it. The tests were created without the genome - they get to make up whatever stats they want. The CDC admitted that only 6% of "Covid" deaths were due to "Covid alone" and the other 95% of the deaths were persons with an average of 4 co-morbidities (hint - they died of cancer, COPD, heart failure etc.).

Now that the CDC lied, locked down and destroyed so much of human health and prosperity, it's time for them to force a toxic bioweapon on us. It's always time for the CDC to do more damage.

It's creepy that the CDC admits 38 million cases of flu 'disappeared' (was reclassified as 'Covid) and 'we don't have flu anymore' at the same time it tells us to get used to being muzzled because Covid will always be with us. Gosh, if the flu disappeared spontaneously, why doesn't the CDC think that Covid can every 'disappear' spontaneously? Why? Because they need Covid to destroy America.

One Month After Biden Announced his Federal Vaccine Mandate!
It Still Has Not Been Formally Issued!

Trending Politics ^ | October 10, 202 | Kyle Becker Posted on 10/10/2021, 4:38:07 PM by Norski

One month after the Biden administration announced a draconian federal vaccine mandate that impacted an estimated 100 million Americans and led to mass firings of public servants, teachers, and medical workers, the federal regulation still has not been formally issued.

The Federalist reported . . in a post on Thursday that noted, “Joe Biden’s Vaccine Mandate Doesn’t Exist. It’s Just A Press Release”:

Biden’s so-called vaccine mandate doesn’t exist — at least, not yet. So far, all we have is his press conference. No such rule even claiming to be legally binding has been issued yet.

That’s why nearly two dozen Republican attorneys general who have publicly voiced their opposition to the clearly unconstitutional and illegal mandate haven’t yet filed suit against it, the Office of the Indiana Attorney General confirmed for me. There is no mandate to haul into court. And that may be part of the plan.

According to several sources, so far it appears no such mandate has been sent to the White House’s Office of Information and Regulatory Affairs yet for approval. The White House, the Occupational Safety and Health Administration (OSHA), and the Department of Labor haven’t released any official guidance for the alleged mandate.

There is no executive order. There’s nothing but press statements.

Despite what you may have been . . . led to believe by the media, . . . press releases/statements have exactly zero legal authority.

“There is nothing there yet that gives employers any mandate,” Stephanie McFarland, spokeswoman for the Indiana Occupational Safety and Health Administration, told The Federalist’s Joy Pullman on Oct. 6. “The president made an announcement on this asking OSHA to do it, but we’ve not yet seen anything come from it yet,”. When the state agency gets any further information, she said, they’ll review it.”

I agree, the nervous, hand-flapping, hypochondriac, COVIDiots are insufferable.

They have a weird religious fervor about medicine and the act like cultists.

[wannabegeek]

Why the hell even encouraged or coerced to get the jab if virus survivability is 99.99999%?

Why the hell even encouraged or coerced to get the jab if SARS-C0V-2 virus no scientist even fulfilled its Koch's postulate, that means the virus cannot sicken a healthy person?

They have inflated and exaggerated the number of cases with fraudulent PCR test, shouldn't be using serology test? But how can they do antibody test if they don't have sample of the virus for comparison? Death numbers that mostly death with co morbidity or death by government's aggressive C0VID treatment protocol.

When this BS going to go away?

“Evidence demonstrates that the approved or authorized COVID-19 vaccines are both efficacious and effective against symptomatic, laboratory-confirmed COVID-19, including severe forms of the disease.”

I guess that is why my wife and I caught it from our “fully vaccinated” sister and brother in law. It probably also explains our “fully vaccinated” neighbors caught it as well. I actually could go on and on just from people that we know personally, not to mention the fully vaccinated “Texas Delegation”.

Of course there are studies from all over the world that show conclusively that we are being led down the wrong path. India demonstrated that ivermectin is a much better treatment than the death protocols that we have been subjected to in this country.

The CDC has made a laughing stock out of itself... and they manage to dig the hole deeper almost every day. It is quaint that you have not been able to put two and two together.

[Karl Spooner]

Even the faithful CDC believers know they are being conned now.

[Sequoyah101]

CDC? Pfffft. Not worth the paper it is written on or the dynamite it would take to blow it up.

Come up with an independent reputable, reliable, credible source.

[heavy metal]

our citizens are being required to be used as experimental lab rats while our government doesn’t require the hundreds of thousands of disease carrying invaders it’s spreading across our country during a “global pandemic” to participate in the same experiment...

our government’s actions and double standards prove the kung flu is a scam...

Yes it will, but only the retarded ones.

Are we really still believing the CDC is a legitimate agency, Brian?

What's it gonna take to snap you out of this brain damage?

[bagster]

The words “science” and CDC do not belong in the same sentence.

Hold your horses, Datura.

Example:

"The CDC is a better science fiction writer than Isaac Asimov".

So you're wrong.

[semimojo]

Thanks for this.

It's more evidence to confirm that the vaccines aren't perfect but have been very effective in minimizing severe disease and death.

I'd like to say the bitter-ender antis will soon have to accept the overwhelming reality but sadly I know better.

[dadfly]

the CDC needs to be abolished. and it has needed to be abolished for long time.

[firebrand]

a weird religious fervor

It's known as caring about others.

Dear Mojo retread troll,

Any statement by the CDC is not evidence. It is government, pharma, Derp State, Chinese booshito propaganda. And you are a shoveler of it.

Now that you know this, you can move along and join the rest of decent humanity.

You're welcome.

[bagster]

It's known as caring about others.

Then why are you killing them?

Hannibal Lecter cared about others too. With fava beans and a nice chianti.
