    The Living & Pure God loves you so much that He sent His Holy Son Jesus from heaven to earth, to be born of a virgin, to grow up and die on a cross for our sins, and to be put into a tomb 3 days and rise from the dead the third day, and He (Jesus) went back up to heaven. We must receive Sinless Jesus sincerely to be God's child(John 1:12).After we get saved by grace through faith in Christ, if we truly love the Lord Jesus Christ, then we will obey Jesus(John 14:15). Mark 1:15 "And saying, the time is fulfilled, and the kingdom of God is at hand: Repent ye, and believe the gospel." Jesus said in John 14:15 "If you love Me, keep My commandments. "There's a real hell. It says in Revelation 21:8 "But for the cowardly, & unbelieving, & abominable, & murderers, & immoral persons & sorcerers and idolaters and all liars, their part will be in the lake that burns with fire and brimstone..." Please sincerely receive Holy Jesus and put your true faith and trust in Him today and repent!

    As soon as a virus mutates the injection is next to useless. Also the tests for covid are useless if it mutates. They will show false negatives. The trials were rushed through with small candidate numbers. And any data processing by pharmaceutical companies that make billions is not something I would be trusting. Nobody wanted to help with an Ebola vaccine because it would not have been cost effective. They are only in it for profit, with no recourse or accountability when things go wrong.

      Not really useless the virus cant really change their spike protein because if it drastically change it will disable the use of the spike protein A.K.A cant get into your cells And the vaccine is targeted to the spike protein so if it did mutate it can still be effective

    I wonder if we'll be getting information about those produced in China (Sinovac & Coronavac) and Russia (Sputnik V). Our president is kinda an Anti-American and have been pushing these vaccines to us pretty hard, even at the cost of our own citizens. The ones in China have pretty low efficacy rate, just barely above passing, and they're more expensive, and being sold by a hostile country that wants to expand against our territorial waters, hence, the vaccine choice is very unpopular save for the president's cult followers who would follow him without question

    To everyone afraid of the side effects: If the vaccine is less lethal and has less harmful side effect than the virus, it is still worth getting. Because you are going to get either the virus or the vaccine eventually (a small number of people will get both, but chances of getting neither eventually are really low with this kind of management) and with the vaccine you are much less likely to die or become disabled than with the virus. And that also applies to the scary-looking (because of stereotypes) Russian or Chinese ones, if they get approved in multiple countries. I would take that if we had enough vaccines in Poland but we don't and won't for a long time.

    PATIENTS ARE DYING BECAUSE MOST DOCTORS DO NOT KNOW THIS INFORMATION. IVERMECTIN SOLVES the COVID-19 Pandemic. Mountains of evidence proving its efficacy is now available It is a drug used since 1975 and is a Winner of the 2015 Nobel Prize 3/28/21 IVERMECTIN is considered as a “repurposed drug” since it was only last Fall that the ALLIANCE discovered it to be a SAFER SOLUTION to the CORONAVIRUS. It PREVENTS Illness, LESSENS SUFFERING and HOSPITALIZATION DAYS, AIDS CRITICAL PATIENTS and THOSE ON VENTILATORS. Ivermectin is good for persons with Allergies, the Elderly, All Phases of Covid, Covid Variants, Long Covid/Long Haulers and Those Refusing Vaccines. IVERMECTIN reduces viral load and replication. Studies have shown action against Yellow fever, Dengue, Zika and others. It enhances Interferon. Dr. Paul Marik formed the FRONTLINE COVID-19 CRITICAL CARE ALLIANCE (FLCCC). This original 10-member international group of ICU critical care specialists and scientists of Medicine evaluated IVERMECTIN and found it to be AMAZINGLY efficacious in the prevention and treatment of Covid-19 patients. Their Website is ALfirst video: “The FLCCC Alliance press conference from Houston TX” 12/4/20 Taken from the website: “In October 2020, the FLCCC Alliance developed a prophylactic and early outpatient combination treatment protocol for COVID-19 called I-Mask+. It’s centered around IVERMECTIN, a well-known, FDA-approved anti-parasite drug that has been used successfully for more than four decades to treat onchocerciasis “river blindness” and other parasitic diseases. It is one of the safest drugs known. It is on the WHO’s list of essential medicines, has been given 3.7 billion times around the globe, and won the Nobel prize for its global and historic impacts in eradicating endemic parasitic infections in many parts of the world. Our medical discovery of a rapidly growing published medical evidence base demonstrating its unique and highly potent ability to inhibit SARS-CoV-2 replication and to suppress inflammation, prompted our team to use ivermectin for prevention and treatment in all stages of COVID-19.

Positive IVERMECTIN results can be seen quickly after administering the initial doses and it is an extremely safe and inexpensive drug. Contraindications list warfarin, however, those who have been on blood-thinning medications have had better results since the Covid-19 virus sometimes causes blood clots.

The World Health Organization stated on 2/15/21 that they will give its recommendations about Ivermectin in the coming weeks. The virus vaccines are being released with questionable safety records with emergency usage authority, whereas, the IVERMECTIN drug, which has a proven safety record for 45 years, needs much more TRIAL DATA to prove its SAFETY. Vaccine companies cannot be sued for any injuries to people so they are dispensed quickly. The US FDA, WHO and CDC have much to answer for in delaying their recommendations on IVERMECTIN during a PANDEMIC. They are not working fast in this CRISIS. Also, some foreign countries look to the USA for medical direction; approval delays are extending suffering and costing the lives of millions with coronaviruses.

    I had Covid last year really badly but recovered. I got my very first shot of Moderna a few days ago and became aggressively sick. I'm reading things about how Covid survivors are already primed against the virus, so the first shot of the vaccine is affecting them the way the second shot does for most people and that two shots may be unnecessary for this group. This would free up thousands of doses for others that need two shots and increase the vaccine supply. Anyone have any input on this? I'm genuinely seeking feedback or answers. I'm not against getting the second shot or anything, but this early research seems interesting and could benefit everyone it seems. I wouldn't want a shot wasted on me that could go to someone else.

      well what you said for most part is true.Covid survivors have severe reaction to the first dose as one would have to second dose.But the part about not needing the second dose is a bit controversial and is being studied right now as far as I know.But you should be safer than most and freeing up vaccine this way is something politicians would most likely decide if they want to increase effective reach but this topic seriously needs further study.

    J&J was the one I got. The "side effects" lasted only 4 days. Mild headaches, extremely isolated joint pain (only at night), and only on one day, I felt tired. That was it. I was one of those lucky enough to have a choice; Moderna or J&J. The latter also only takes two weeks for you to develop a good defense. No complaints.

    It is so hard to find any real information on these vaccines. My concern with the Moderna and Pfizer is, primarily, the actual makeup of the lipid layers. I, of course, have some reservations with respect to bypassing the normal immune response with experimental mRNA but I have recently begun to experience extreme allergic reactions after never having any allergies. Ferrets suddenly make me pass out and something, somewhere, actually locks my ear drum and renders me deaf from time to time. I have a real concern with the elevated level of allergic reactions to the materials being used and the fact that some of those materials are not particularly gentle in biological environments. What are they using to coat the Johnson and Johnson? All I can find is the same "magic" of the spike protein blabber. What is the delivery system? I'm more comfortable, intuitively, with the more natural sequence in the Johnson and Johnson and the fact that it is not a new technology being used but what I can't find is what it is and whether or not it has been used in human subjects without elevated allergic response. People are reporting side effects that are consistent with a toxin being processed through the body and there seems to be a commitment to ensuring us that this is just the immune system having an extreme reaction that it won't have when introduced to the wild virus...and that doesn't, entirely, make sense to me. The total lack of real information is really stressing me out. For people who have an elevated chance of having a severe allergic reaction to the vaccine, the absence of information is overwhelming. At this point, I'm going to hold off because I can't make a decision based on minimal information and a lot of general graphics and descriptions. Even medical professionals are telling me they really can't answer my questions. I think we all understand the whole DNA, mRNA, protein identification, immune system response thing...I'm looking for information on the stuff we don't know about the vaccines and this is very confusing, considering they are asking the entire population to sign up for a clinical trial.

Last time you spoke about it in September 2020, and at that time your talk was disparaging. The title was like "what is wrong about Sputnik V", but later it was changed.

    So, remind me, how many women did J&J kill with their baby powder?

    Could you make a video on why the vaccine is not approved for children?

    More than half of the source links are duds, just FYI. Not sure which ones cited which specific pieces of information, either.

    1:14 That's confusing🧐. Why give us an estimate that includes the placebo group? effective is that placebo vaccine? 🙃

    The Janssen vaccine is actually produced in collaboration with J&J but not by them. It has been fully developed by scientists from Janssen (not the same as J&J) in Leiden, the Netherlands.

    I thought the point being made of the testing being a bit later and perhaps including variants to be interesting. The pfizer and moderna were tested earlier and would not account for variants. I got the pfizer but after hearing that I would have been happy with jansen as well.

    All the vaccines could be used as a single dose vaccine. It is just that two doses improves protection.

    Thanks for the video. I'm looking for material to show to some people skeptical about the vaccines and their safety. how is it ensured the DNA the vaccine is carrying can't interact with the human DNA? Is there some literature about that somewhere?

      there must be somewhere deep within the papers since I highly doubt they would half ass it especially since so many scientist and non scientist all over the world are watching them.But I do not expect it to be simple

    J&J vaccine it the one the gov really wanted. Relatively cheap, easy to distribute, and one shot. Fair enough, those really do matter. I still think we should be investing heavily in the infrastructure to make mRNA vaccines cheaper and easier... Those give us a real quick response capability, and mRNA based treatments for lots of other stuff (not just vaccines) are likely in our future. PS: one problem with viral vectors is that the immune system also develops resistance to those vectors, so we can't just put different DNA in the same vector and use it over and over for different diseases or variants.

    Got the first shot of the Moderna vaccine. No side effects other than my left arm where I received the shot feels like it has a deep bruise. Not sure how they keep the vials super cold. Vaccines were given in an open air covered concourse in a community college.

      Nice. I was just saying somewhere else idk why but I'd feel more at ease about taking this vaccine than the others, especially if it is coming out of the Netherlands. Hopefully the local pharmacies or my doctor here will have this one available for me to take when borders open so we can go home. We're stuck in the US 😢

    If placebos are also " Okayish" then why don't we administer it to the majority of people as the first line of defence and then distribute the vaccines at their own pace??
