First COVID-19 Vaccines May Not Prevent SARS-CoV-2 Infection Says Fauci

The first generation of COVID-19 vaccines may not prevent people from becoming infected with or transmitting SARS-CoV-2 virus (COVID-19). According to Anthony Fauci, MD, director of the U.S. National Institute of Allergy and Infectious Diseases (NIAID) and other infectious disease experts, the best that COVID-19 vaccines may do is prevent people becoming severely ill and dying.

“It’s quite possible a vaccine that only protects against severe disease would be very useful,” said Robin Shattock, PhD, professor of mucosal infection and immunity at Imperial College London.1 Dr. Fauci agrees. Regarding the experimental AZD1222 vaccine (formerly known as ChAdOx1 nCoV-19) being developed by Oxford University and biopharmaceutical company AstraZeneca plc, Dr. Fauci said:

I would have liked to have had protection against infection. But then again, it depends on what you’re looking for with the vaccine. That vaccine doesn’t look like it’s a knockout for protecting against infection, but it might be really very good at protecting against disease.1 2 3

AstraZeneca Unsure AZD1222 Vaccine Will Clear SARS-CoV-2

In a recent interview with the BBC, AstraZeneca CEO Pascal Soriot said that although it is unclear if their vaccine would “completely clear the virus,” he believes that it could still be considered effective if it kept people from getting COVID-19 symptoms. “The question around the vaccine is will some patients need a second dose and also will the vaccine eliminate the virus from the body of the people or simply protect them against being sick. But being protected against being sick would already be a big plus,” Soriot said.4

“That’s really important,” said BBC interviewer Andrew Marr, who added, “But it’s possible that this vaccine will stop you going to hospitals, stop you from getting pneumonia and becoming very ill, but will allow the virus to carry on transmitting through the community until it reaches someone who hasn’t been vaccinated.”

Soriot did not dispute that possibility. He noted that that it wasn’t clear how contagious a person with the SARS-CoV-2 virus would be [after getting vaccinated] and stated:4

Even if the vaccine doesn’t eliminate the virus from the body of every single person we’ve vaccinated, the question will be, how long will the virus stay in the body… maybe people take a little longer to get rid of it. And the other question will be, if the [virus] is still there in your nose, can you be contagious, can you infect someone else or not? Those are questions we don’t have answers for yet.4

Are Vaccines That Don’t Prevent Infection Considered Effective?

The problem with vaccines that will not actually prevent SARS-CoV-2 viral infections is that most people who get vaccinated will assume they are protected and will not take any further precautions either for themselves or to prevent transmission to other people.

According to Michael Kinch, PhD, director of the Center for Drug Discovery at Washington University in St. Louis, Missouri, “My guess would be that the day after someone gets immunized [for COVID-19], they’re going to think, ‘I can go back to normal. Everything will be fine.’ They’re not going to necessarily realize that they might still be susceptible to infection.”1

    I have a problem with making our members of the military guinea pigs. They are doing enough for us and we need to use it on prisoners first. Especially those on death row.

    • Miko   July 13, 2020 at 6:06 pm

      The left hates the military. Let’s sterilize them.

      • Jay   August 12, 2020 at 12:34 pm

        Stop……this is red baiting. The left doesn’t like phony wars, the libertarians are in agreement…when will the right catch up? Is it humane to send soldiers to die for imperialist aims? When our country has the highest rate of inequality in the world?

  3. Dennis O'Hara   July 13, 2020 at 5:35 pm

    I thought the whole idea of a vaccine was to create immunity? Am I missing something here? You want to inject a toxic substance into a person calling it a vaccine and there is no immunity from receiving the vaccine? I call that fraud or false advertising or unethical or malicious, but I would not call it a vaccine.

  4. Deja   July 13, 2020 at 6:03 pm

    Won’t prevent getting infected? Then it’s not a vaccine! It’s just a treatment. And there already is a good treatment out there with a 97-99% success rate if given IMMEDIATELY after first sign of symptoms and it only costs $20 so why still make a vaccine? $$$$$ greed who knows whats gonna be in that thing?

  5. Miko   July 13, 2020 at 6:04 pm

    They’re already setting up the narrative that the vaccine won’t work.

  6. Angela   July 13, 2020 at 8:28 pm

    I will never ever get the so called vaccine. I WILL NOT ALLOW SOMEONE TO TRACK ME.

  7. Joanna   July 13, 2020 at 8:46 pm

    EXACTLY Miko!! Only one that will work is Bill Gates vaccine….theres more of the Narrative! Got to make Billions of dollars on this vaccine and control the people! What is the Actual TRUTH in all of this hype on COVID-19!! And using our Military is Monstrous!! I remember when they used some of our Military as Guinea pigs!! I can’t believe anyone would even allow this now!! Social Media is so prevalent that anything gets out about this to the public there will be an uproar…When it goes south and causes serious harm to our Military people!!

  8. Paulie   July 13, 2020 at 8:51 pm

    I’ll try any of the vaccines, just none of the Bill Gates specials that want to alter my genetic RNA or DNA structures… “just say NO”…

  9. M B   July 13, 2020 at 10:08 pm

    Test it on death row inmates, not the military.

  10. Jay   July 13, 2020 at 10:12 pm

    Deja, just curious, what treatment is that? Remdesivir?

  11. George   July 14, 2020 at 12:14 am

    Is this a joke? They’re already making excuses as to why it won’t work telling us without any proof whatsoever it might prevent you from getting sick while being infected! Meanwhile they’re suppressing cures for the disease allowing thousands to die. Hydroxychloroquine, azithromycin, and zinc cures the disease when given in the beginning or intermediate stages. I cured my COVID using chlorine dioxide. I was symptom free in 3 days. Felt a little weak for a few more days. Never had any lung or respiratory symptoms, only a low grade fever. Gone in 3 days with no other symptoms and I’m 70 years old. Another cure that is clinically proven is Budesimide via a nebulizer. Doctor in Texas claims 100% cure rate.

    What is wrong with Americans’??

    Call for Fauci & others to be prosecuted!!

    Get your President to remove the Legislation for your Vaccine “Court” and pass Legislation to change the terminology from Vaccines to a Medicine!!

    Educate your people to the miscreants in your public offices both political technical and others. How they lie and manipulate the taxpayers of USA.


    Dee _ an Australian who is fed up with all things American

    • Adri   July 14, 2020 at 8:47 am

      I am very curious what your reaction is to what Australia is doing? They have said that the vaccine will be compulsory and that it will be enforced by the military. Maybe I have this information incorrect. I was interested in taking my kids to Australia and New Zealand, but now I’m concerned to go there.

    • Nat   July 14, 2020 at 9:25 am

      Dee, it is unfortunately not just a matter about Americans! Evil, need for power and control, like stupidity and ingnorance is unfortunately well and evenly distributed around the world. Our only protection is behind aware, being critical and refusing to abide by what does not feel right.

      The topic at hand in this article is actually typical of misinformation and a way to continue leading people to that wide open road of fear. Here is a good quote (sorry I did not write down the author):
      “all medical and non medical authorities on vaccination agree that vaccines are designed to cause a mild case of the diseases they are supposed to prevent. But they also know and admit that there is no way whatsoever to predict whether the case will be mild or sever- even deadly.”
      So of course this or any other vaccine will not prevent you from getting infected by this or something else, and of course it will not get rid of this or any other pathogens, because this is NOT what a vaccine is supposed to do.. and adding a second, third, and so on dose will not do anything either EXCEPT create a storm of reactions from the body to get rid of all the toxins and poisons injected and then most likely create a host of other diseases or conditions. and watch after they use this on military personnel (and you will never know right away with what consequences), there will be a massive propaganda for mass vaccination using all the leftovers.

  13. Paula   July 14, 2020 at 8:11 am

    A “vaccine” by definition is a biological preparation that provides active acquired immunity to a particular infectious disease. Already by far most people who get covid 19 have either no or very mild symptoms so what is the point??

  14. Adri   July 14, 2020 at 8:43 am

    The military members (who don’t have choice of refusal) will get an untested vaccine first?!? And the makers have are completely free of any responsibitly if people have adverse reactions or die. This is wrong and terrible.

  15. Susan   July 14, 2020 at 8:36 pm

    It’s not what’s wrong with Americans, it’s that we are mislead and lied to by people in power – the CDC, powerful industries, certain billionaires, etc. A small percentage of Americans learn the truth, or believe the truth when they hear it.

    Due to corruption and internet censorship, internet searches as well as social media platforms have made it much more difficult to find the truth.

  16. JB   July 14, 2020 at 11:51 pm

    I agree, Fauci should be investigated. I don’t understand why nothing has been said publicly about his dealing behind the scenes. Him being involved in the devolpment of Vaccines is a conflict of interest given his political position.

    We have learnt very little about this particular virus even though the whole world has been brought to its knees by it.
    China have finally admitted that the virus did not come from the Wuhan market as we were all lead to believe but they are still dodging responsibility. I suspect other countries may also be implicated.
    We hear a lot about how we need to come up with a vaccine or things will never be the same. Billionaires like Bill Gates leading the way and advising on the use of vaccines. No offence but the man has zero medical background. His philanthropic foundation “the Bill and Belinda Gates Foundation” gives to many institutions of science that develop vaccines including NIH, CDC, GAID, Oxford university (Astra Zeneca) to name a few. Bill Gates donated over USD 3.4 billion to the WHO so he has a huge influence there.
    Through his charitable foundation he has doubled his personal fortune to USD103 billion. Questions?

    What I do find disturbing is that if anyone questions anything regarding vaccines or SARS-coV2/, or anything that goes against the status quo, they are automatically label unscientific, quacks or conspiracy theorists.

    What we need is real investigative journalism into this crisis.

  17. Rob   July 16, 2020 at 6:32 am

    Well, NO vaccine prevents the recipient from still not being a carrier/ transmitter. The great falicy that many believe is that they can no longer give another a virus because in their minds, a vaccine repels viruses from their body.

  18. Ron   July 21, 2020 at 11:09 am

    @Jay at $20 bucks @Deja was probably referring to Hydroxychloroquine or chloroquine. Remdesiver cost over $3,000.

    The Left is using this “Pandemic” as a political ploy and blame it on Trump. Just as they tried to impeach him and other tactics used, since he has been in office (which didn’t work). Fauchi and Birks are getting paid by Bill Gates and his wife; evil people, whose intent is to depopulate the world. Watch “Event 201” and his Ted talk speech. Listen to him speak of releasing genetically modified mosquitos to infect people, and how certain people will die from vaccines. These people should be locked up for their crimes against humanity! Dr. Judy Mikowitz, John F Kennedy, Jr., Dr. Rashid Buttar are waking up the American people to the truth. Swamp creatures are advising Trump and he appears to be complying with mask wearing now (which the liar Fauchi said, originally, won’t protect anyone from Coronavirus), has promoted dangerous 5G and is fast tracking vaccines for Coronavirus (which has not been tested on animals and thus far, no vaccine has proven safe for use in humans, to date.
    Pray our President will take action to protect the American people. I have been a Trump supporter and unless he takes action to stop this nonsense, I may not vote, in Novemer.


  20. Jay   August 12, 2020 at 12:40 pm

    The solution to stopping CoV19 is to stop testing. Fauci knows this. rePCR are fatally flawed false diagnostic, Ig antibody never had unique proteins to be specific or sensitive. Tell everyone you meet, know, family etc…..stop testing!! 88 to 98% recovery depending on age/risk group.
