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.
more baby, give me more
Statistics are your friend. Covid 19 has killed 720,000 in the United States alone, approaching 5 million worldwide.
The vaccine hasn’t even come close.
It's known as caring about others.
____________
It is so kind to force experimental mRNA injections developed in under a year with an unproven technology on everyone regardless if someone needs it or not an regardless of the consequences. If someone refuses your “kindness” you frothing mad fanatics want to other them and force them into poverty. You and your Nazi doctor clown posse want to inject small children and pregnant women and are far to comfortable with force and violence.
What does a hypochondriac, corporate fascist like you do when you aren't trying to “help” someone?
COVIDiots like you are deluded, fanatical, and dangerous.
No it hasn't. More Derp State fakery.
If statistics are your friend, stop listening to the wrong people for yours.
Yeah, I'm a retread from when I was banned in 2001.
Good to see COVID isn't the only area where critical thinking eludes you.
This I know. And weren't you the cutest little liberal troll back then.

Remember, none of these entities want you healthy. Instead, they are constantly inventing new "illnesses" to pick money from your pocket or new "crises" to keep you off balance, to impoverish you and to strip you of your freedoms. The CDC is part of that diabolical machine. Believe nothing coming from it including "and," "a," and "the."
I flap my hands around and wonder what has happened to Free Republic.
the first thing anyone who has made their living with numbers will tell you about statistics is this,
“There are lies, damn lies, and then there are statistics.”
you say absurd things like “Statistics are your friend. Covid19 has killed...” proving you haven’t got a clue about how to apply statistics to anything.
Congratulations. You are the one millionth person on Free Republic to say “you can’t trust the source” when you have no good argument.
Oh sorry. Bagster got there before you in the When You Don’t Have Any Answer Throw Dirt at the Statistics Sweepstakes.

--The notorious 1976 swine flu vaccine scandal was catalyzed by mass hysteria whipped up by CDC junk scientists clamoring for more money; Congress obliged and nearly 45 million Americans were unnecessarily jabbed with a vaccine for a disease that had fizzled by the time the shots were ready. The vaccine resulted in an increased risk of developing Guillain-Barre syndrome -- leading to muscle weakness and paralysis.
--In 1999, the CDC misspent $22.7 million appropriated for chronic fatigue syndrome and was investigated in 2001 for squandering $13 million on hepatitis C research.
--In 2000, the agency essentially lied to Congress about how it spent up to $7.5 million earmarked each year since 1993 for research on the deadly hantavirus. "Instead, apparently without asking Congress, the CDC spent much of the money on other programs that the agency thought needed the funds more," The Washington Post disclosed at the time. The diversions were impossible to trace because of shoddy CDC bookkeeping practices.
--In 2009, the CDC recalled 800,000 doses of swine flu vaccine for children ages 6 months to 3 years after the products manufactured by Sanofi Pasteur failed potency tests.
--In 2012, the CDC's main building housing infectious anthrax, SARS and monkeypox gases was discovered to have been leaking deadly pathogens due to a flawed engineered airflow system.
--In 2014, the CDC's lackadaisical response to Ebola virus gave the greenlight to Patient Zero Thomas Eric Duncan and infected medical personnel to board commercial airlines while ill -- exposing untold numbers of travelers to the deadly disease. Expensive isolation chambers that had been subsidized by taxpayers to the tune of $15 million sat buried in a Georgia warehouse.
--For the past few years, the agency has employed a fear campaign to induce Americans to get regular flu shots (formulated based on guesswork) using flawed statistics and despite international scientific conclusions that there is "no evidence" to support the CDC's assumptions that the vaccine reduces transmission of the virus or the risk of potentially deadly complications.
--Just this week, the Informed Consent Action Network reported astonishing results from its lawsuit against the CDC to obtain scientific documentation for the agency's claim that "vaccines do not cause autism" -- specifically for the first seven vaccines given to your child in their first six months of life. CDC had stonewalled, and then finally produced 20 studies
-- 18 of which were irrelevant to ICAN's public records request and two of which suggest that vaccines may indeed cause autism. In other words: The CDC is lying while continuing to smear vaccine critics as "conspiracy theorists" and public health threats."
Dr. Michael Yeadon states most covid-19 deaths are directly attributed to Remdesivir or Midazolam
Dr. Michael Yeadon is the former vice president and chief scientist for allergy and respiratory at Pfizer.
i don’t read statistics...
i watch people’s actions...
our government’s actions and double standards prove the kung flu is a scam...
bs word play won’t get you anywhere with me. and my comment has nothing to do with anyone else’s here. not really talking to you, really i’m attempting to defend the less statistically astute from what is imo, your misinformation and misuse of statistics. i’m simply calling out your obvious mishandling of a very controversial statistic. i.e., the *estimated* number of deaths from covid19. for example, you didn’t even bother to source your statistic, let alone provide any analysis, confidence measures, or critique on it’s internal consistency from a statistical standpoint.
thus you give the appearance of just stating it as a fact, which immediately makes you look like you don’t know what the hell you’re talking about.
and given the nature of statistical analysis and the publicized and problematic ways that various entities like for instance, the very discredited CDC in this thread, have gone about compiling and reporting it, your presentation is absurd as i said previously.
*bows*
Thank you, thank you.
I'd like to thank the CDC for being, well....the CDC.

We know.
Of the 720,000, about 85% were murdered by pharma and the medical industrial complex. A nurse friend who is offering early treatment to people in her town, gratis no less, has not lost a single patient. My own MD, who has treated hundreds using the FLCCC protocol, has not lost a single patient. Dr David Brownstein has treated hundreds with zero deaths. There are many others. How sad that people have to often be saved in secret! The CDC treatment guide is a roadmap to genocide, and that is not an exaggeration. The network I support fights hospitals daily to advocate for cv19 patients who are victims of criminally substandard care with zero effective therapeutics offered. We know their death routine. Some day these toady MDs and nurses will be called to account for their pride, ego, stupidity, arrogance and criminal negligence.

I will give you a clue.
The Republican base is tired of the Republican leadership's lies and the outright betrayals of Republicans and patriotic Americans. Thanks to the Bush Crime Family the GOP has muzzled and incapacitated our ability to fight the communist onslaught for 40 years and we are mad as hell. We are beginning to rejecting both the HOP leadership and their toadies. This rejection is happening in the real world and online here online at Free Republic.
The scamdemic is nothing but cover for a globalist, totalitarian coup and any Freepers that advocate for useless masks, illegal federal medical mandates, and fascist lockdowns are committing a disgusting deception and betrayal.
People that advocate evil like that are not out friends and allies. Go post on DU.
