    1. @andre1442 No this aint the best we can do…hydroxychloroquine has been treating patients this entire time.

    2. No problem. COVID-19 will take care of you and the rest of the people who only trusts info on the internet from non experts. May want to do a search on polio or chicken pox before you make rash decisions or posts.

    1. @Kim Jong Un kim jong un was actually the president of china before he was adopted by a secret documentary featuring george soros and his goons. The strung together GMO lies to feed to americans and now thousnads of people are dying, open your eyes

    2. @BWZ Archive yea man we need to wake up. I heard on my anti-vax facebook page that the deep state is now the shallow state because we’re flushing them out one by one!

    3. @Kim Jong Un im glad you have woken up to the evils of the deep soros state, musha allah brother, stay safe, and remember coronavirus isnt real

  1. How can an accurate vaccine be developed for a pathogen that can’t doesn’t even have a 50% test accuracy?

    1. Let that vaccine in their butt first.
      The vaccine doesn’t grantee why should we have to take. They still didn’t have HIV or AIDS vaccine why worry about this one.

    2. @Elio Decolli they would have tested positive a hundred years ago too, but that doesn’t prove you don’t have the uh… Virus. Right, thats a good one.

    3. @Braden Means much the same way MTV played mostly music videos when it first started off, but transformed slowly into something more obviously nefarious.

    1. you will want to watch this: https://banned.video/watch?id=5f19fff068370e02f296c69d

      TheirTube has been blocking medical information and now banning doctors from sharing their CURES for covid-19, H C Q , Z paks , and zinc sulfate … Even when literally dozens of medical doctors meet with Vice President Pence, tell him, and the whole world COVID is treatable, theirTube banned free speech to kill more people. Having known treatments, and denying patients medications that could save them is unethical and immoral. COVID Shutdown is a complete Fraud.

    2. I agree. Reading the information is much better in my opinion. Eventually people will be too stupid to read and will simply watch videos instead of reading articles.

    1. Anthony Lapuma no you can’t rush science there trying as hard as they can under pressure and time crunches and it’s more like idiots like you who will mislead people and cause unnecessary deaths to prove your little point.

    1. @Full Body Joe 🤣💉💊🏃‍♂️🏃‍♀️🏃‍♂️🏃‍♀️🏃‍♂️🏃‍♀️👻👹👻👹😈😹👻

    2. @KO_POWER 777 Lol yeah, I have no doubt about it.

      Remember vaccines are safe. Robert f Kennedy Jr proved the vaccine companies didn’t send safety status updates to congress for 30 years. 🐂💩

    1. @Thomas Dickensheets The shots are killers – it is your BILL OF RIGHTS, freedom of religion and belief, that says NO – Shove that filthy needle in your own arm pal, STAY AWAY from our Children with your U.N. mandated toxic sludge.

      America : READ YOUR BILL OF RIGHTS !
      Gotta wear a mask ? No. Your body, your choice. you want to wear one ? go ahead, I do not wear masks ever – My faith is in GOD, not blue paper MADE IN CHINA.

      Can’t go to synagogues or church or mosque or temple ? No. We will all go, and we will all worship GOD, not Bill Gates.

      Gotta stand 6 feet apart ? No. Freedom of assembly – i’ll stand where I please, when I please. Say no to GPS limiting 6 feet seperation to determine the number of people in a room… (the 6′ distance is the resolution of cellular phone technology , if people clump together it looks like 1 person).

      Comrade Tracers demand a list of names of people, they want the children’s names ?
      No. No Warrant ? Do not talk to us.
      Gotta Warrant ? 5th amendment – Americans are never telling you anything – go pound salt.

      WAKE UP U.S.A. The communist attack against America is easy to over come – just DON’T BELIEVE THE HYPE…

      And begin SCREAMING the Bill of Rights at the top of your lungs at any one attempting to perform Unconstitutional actions against you, your business, or your people. God Bless America.

      Honor the Constitution, not the Rule of Force.

      WE THE PEOPLE RULE.

    2. Yea….they’ll probably just give them a placebo or liquid vitamins instead of the actual “Covid-19 Vaccine” just so people can follow suit with getting the actual “vaccine”.

    1. Phase 5: Global Genocide of 4 Billion people… murdered by Antibody-Dependent Enhancement
      After a person is vaccinated, they develop an immune response to that disease subtype. The immune response produced specific antibodies to that subtype specific surface proteins that prevents the virus from binding to cells the viruses infect and gaining entry. However, if another subtype of virus infects the individual, the virus will activate the immune system to attack it as if it was the first subtype. The immune system is tricked because the wild subtypes have very similar surface antigens. The antibodies bind to the surface proteins but do not inactivate the virus. The immune response attracts numerous macrophages, which the virus proceeds to infect because it has not been inactivated. This cytokine storm and drowning to death in your own body fluids is referred to as Antibody-Dependent Enhancement (ADE) of a viral infection. This makes the viral infection much more deadly. All test animals suffered and died when vaccines are rushed through the system and safety testing has been skipped or ignored all together.

    2. Check my covid-19 is a fix part 2 seriously people open your eyes to the real world see this is all part of a plan to wipe us people out its to stop us living the government have left the country in debt it’s it’s a money grabber   https://youtu.be/5R3vlrxglyk

    3. You forgot!!!
      Phase5 6 7!
      Depopulate
      More depopulate!
      Enslave the rest of humanity for their resources! 😠😠😠

    4. @bluegoldginger Slaves need food… The Boston Dynamics ‘bots and other automation won’t even need that.
      The Economic Genocide of America is flowing nicely, more than another 1 million people reporting they are unemployed…

      LA has begun mass evictions – tossing whole families into the streets… They are the lucky ones, up north – the temperature is dropping – freezing, hunger, homelessness – Death Stalks U.S.A. like wolves hunting sheep..

      During this whole Scam-dem-ick, I am honestly shocked how no one is fighting back, sheeple to the slaughter – no one stands up for their Constitutionally protected natural god given pre-existing Human Rights, the Bill of Rights outlines much of it…

      NO ONE… NONE, Can NEVER shut down churches, mosques, synagogues, reading rooms, temples, or other houses of worship – no, gestapo thugs emergency powers are LIES…
      Can NEVER order your business to close, 4th amendment rights to private property…
      Can NEVER ask anyone anything – these Comrade Tracers demanding lists of names of worshipers – they want the names of the children ? Why ? How about: HELL NO !
      No Warrant, no entry – GET OFF OUR PROPERTY. Oh, you do have a warrant ?
      5th Amendment – we are not telling you anything… Feel free to call the lawyer and he can tell you we won’t speak to anyone.

      And now – an open assault on the second amendment – the NRA. First they want to SHUT YOU UP by banning your free speech on the internet, now they want to SHUT YOU DOWN and cancel all
      AMERICAN Culture…

      If China only knew boiling American frogs would be this easy back in the 1900s – they could have skipped the Korean and Vietnam wars, and just gone straight to attack the mainland USA with asymmetric warfare – people this easy to push over are not even a challenge. It’s embarrassing.

      So, it looks like USA is done… Let’s hope India puts up a better fight, and we don’t see their politicians kneeling before Xi Jinping like all those spineless rubes in Washington D.C., kneeling before the communists, worshiping Xi Jinping…

    1. They already signed the legislation to give it to the native Americans first. They passed it off as a good thing. Usual corny titled piece of legislation forgetting the name though

  2. Wake up the government is trying to put a chip inside all of us they wanna control us this covid 19 was planned out to get us worried wake up people only God can protect us 🙏❤️

  3. What about the nigerian doctors that have been curing ppl already using hydrocloriquine? Oh yeah the media doesnt want you to know about that

    1. @Topher C its proven not to work with the scientists fake reports I’m gonna take my chances believing doctors that are hands on treating covid patients not some scientist writing papers in his lab for the government 🤷‍♀️. Oh and I take hydroxychloroquine daily for lupus and I’m GREAT no mask needed 👏👏👏

    2. Tiffany Eulalah that’s a hell of a take on the mask wearing. I’m still trying to figure out what’s in it for the scientists publishing “fake reports”. These are good people who dedicate their lives to help better ours, I know a few for myself, and this is how some of you choose to repay them.

    3. @Kathy Parrish just because they try it and person doesn’t survive doesn’t mean it’s killing people.

  4. Who needs to see the mid or long term effects…as long as the person seems to be fine after 65 days let’s inject everyone with it. Lol

    If kids suddenly are born with immune system disorders and 8 fingers, we can blame it on pollution

  5. Covid is great, it single handedly killed all the other diseases and cured climate change in just a few months.
    Good job covid, u da real og

  6. This fake vaccine is all about the money, whoever hold the patterns for this, will make hundreds of billions of dollars, all for a flu symptom cold😠🤔😠🤔😠, people have been hoodwinked

    1. @• Grey Slushii • What he said is actually true, vaccinations produce mass amounts of money in the first place. I strongly believe that COVID is just a illusion, and a bunch of lies, fake statistics, fake deaths just to scare us and eventually go for vaccinations and wear a mask for some odd reason.
