Researchers working on Covid-19 vaccines have smashed speed records, bringing new vaccines from development to distribution in less than a year. They did this with the help of billions of dollars of unprecedented global investment -- but also, in some cases, with a new type of vaccine technology.
There are four traditional types of vaccines, and they all require the growing and handling of live pathogens in a lab, a time-consuming process than can add months or years to development. But two new types of vaccines skip that step altogether by moving that work from the lab to our bodies. mRNA vaccines, like the ones from Pfizer-BioNTech and Moderna; and Adenovirus vaccines, like those from Johnson & Johnson and AstraZeneca; do this by sending genetic instructions directly into our cells, which then produce the harmless protein the body needs to learn to fight Covid-19. Because these proteins are produced from within cells rather than injected from the outside, they may be less likely to provoke adverse reactions in the recipient.
The result has been a host of vaccines developed faster than ever. But it's also ushered us into a new age of vaccine technology, one in which we can send our own bodies the instructions on how to protect themselves. That technology is already being used to drive research on vaccines for HIV and cancer. These new types of vaccines are weapons we developed to fight the coronavirus - but their real impact is just beginning.

  • This video focuses on the two new types of vaccines, but as we say at 2:00, not all Covid-19 vaccines fall into those categories. Here’s a list of some of the leading vaccines, and which types they are: mRNA vaccines: - Moderna - Pfizer-BioNTech Adenovirus vaccines: - AstraZeneca - Johnson & Johnson - Sputnik V - CanSino Recombinant protein vaccines: - Novavax Inactivated virus vaccines: - Bharat/Covaxin - Sinovac - Sinopharm

    • The mRNA doesnt get into your DNA at all. Your cell just reads that mRNA and makes proteins from it. It then degrades quite quickly.

  • Before development: mRNA (Pfizer & Moderna) will reduce cost & time to make compared to Adenovirus (AstraZeneca & JJ) After development: mRNA taken longer time & higher cost to make compared to Adenovirus Vaccines. So, is mRNA really a "serendipitous" discovery??? Which proven to have "high efficacy" plus "highly customize-able instructions", even though knowing fewer mRNA vaccines being produced compared to AZ & JJ so to meet challenging the world demands.

  • Great video! Thanks! 1) It's not exactly messenger RNA (mRNA). They developed a "MODIFIED" version of mRNA (moRNA) with Pseudouridine. Yes, mRNA does not go into a nucleus of a cell. Where does Pseudouridine go after moRNA metabolism? Can it go into a nucleus and incorporates into DNA? Can it change information in DNA? Can it cause cancers? How soon could we see those cancers with pseudouridine changes? 2) All side effects in other vaccines trials happened in the first 2 months. Can we compare the old vaccine technology and the new modified mRNA technology? 3) Why do we have any side effects with the new modified mRNA technology within first 48-72 hours, when no antibodies are detectable (or even not produced yet)? What chemicals in the vaccine buffers can cause it? 4) Can the newly synthesized Spike protein interact with ACE2 receptor and cause any signaling? Can it release the von Willebrand factor (VWF) and cause clotting?

    • It doesn't make the virus, it just gives instructions to the cells (specifically to ribosomes) to synthesize the same type of protein found in the spikes of the SARS CoV-2. Your immune system develops antibodies based on that foreign protein, just like in the real infection but without its devastating consequences. After that, the mRNA is destroyed.

  • This left out the liposomes, the delivery vector for the mRNA. BioNTech developed a number of these for targeted delivery within the body. They are made up of phospholipids and probably cholesterol to keep the membrane supple just like the cells of our bodies. The liposomes are proprietary so what is in them is not specified but phospholipids can be can up of a wide array of amino acids that may influence how they travel or merge with specific cell types. This is the really intriguing part of of this novel approach because it may open up a new technology. If this can be honed to target cells with disease causing alleles this may be a method of delivering mRNA gene therapies.

  • They didn't tested it wel on discovery development and preclinical trials normally (on animals) to know the side-effects.But licensing, manufacturing and distribution when the vaccine does not guarantee that you will not be contaminated cause you can still get it. It will take 5-10 years maybe more to see these effect like on the Mexican influenza in 2009. Look what happend than. So know I wil not be vaccinated as this is not tested well at all and forgetting the human aspect of it all.

      Thomas CullenThomas Cullen7 kun oldin
    • @Thomas Cullen Ok so you have just shown that you have done absolutely no research at all and are just making things up. NO vaccine (except for a very few sterilising vaccines) will stop you getting the pathogen and if you can get the pathogen you can transmit the pathogen. ALL vaccines will greatly REDUCE (not eliminate) the possibility of transmission as it will lower your viral load and the less you have the less you will expel the less chance of transmitting. The mRNA vaccine is exactly the same it stops you getting the disease it does not stop you getting the pathogen.

      Jimmy SwaggartJimmy Swaggart7 kun oldin
    • @Jimmy Swaggart Also, this mRNA injection does not disrupt transmission of the virus by those who receive it. Vaccines do.

      Thomas CullenThomas Cullen8 kun oldin
    • @Jimmy Swaggart Please provide link stating that the mRNA injection provides immunity.

      Thomas CullenThomas Cullen8 kun oldin
    • @Thomas Cullen Ah yes it does stimulate an immune response and yes it does provide immunity there are plenty of scientific papers out there as well as the clinical trials. This new mRNA vaccines does almost exactly what the virus does the virus enters your cells and tells your cells to make copies of itself. The mRNA vaccine enters your cells and tells your cells to make a copy of a S protein (part of the virus) so that your immune system can recognise it and make antibodies for it. This has been proven in over 30 years of research and development in mRNA vaccines. Dr David Martin a financial analysist who runs a company called M-CAM, which analyzes patents and intellectual property to estimate the investment value of companies. So your listening to a financial analysist on vaccines and believing him. So a financial analysist who owns a company which analyzes patents and intellectual property to estimate the investment value of companies is telling you that this vaccine is not a good thing and that the whole thing is made up so please follow me on this, a FINANCIAL ANALYSIST who makes money from advising other companies where to invest is telling you the whole thing is planned. Humm I wonder who would have a lot to gain from this? Now I normally do not do this but I will give you a chance here. Do you want me to post further information discrediting the claims made by this Dr Martin or are you good. If no response I will assume you want more.

  • Wait so the mRNA one basically make your own cells produce the spike proteins and then let your immune system deal with it, so does your immune system attack the individual spike proteins while the spike proteins are still inside of the cell or does the spike protein go outside of the cell? Or do they attack just attack the whole entire cell?? Also if the AZ vaccine is similar to the J&J one, why does the AZ vaccine dropping people left and right with these clotting news?

    ZekolwolfZekolwolf9 kun oldin
    • @Vary Olla Ah so you have to sacrifice some cells so that our body can develop the immunity, but since spike protein does not infect other cells it won't replicate. So does that mean the amount of vaccine gets injected into our body determines the amount of cells we "sacrifice"? for 4, I was wondering how come the other 3 vaccines don't have a high rate of clotting like to AZ.

      ZekolwolfZekolwolf8 kun oldin
    • 1 - spike protein manifests on the surface of the cell via the Major Histocompatibility Complex. 2 - presence of the antigens triggers T & B-Cell activation leading to antibody formation. 3 - cells are eventually destroyed via cellular apoptosis to be replaced by new cells. 4 - the incidence of clotting issues is already associated with Covid infections. So the number involved with the AZ vaccine is a drop in the bucket. Actual Covid is already killing thousands of people a day - especially elderly who also are the ones with clotting issues post-vaccination. So a few hundred cases out of tens of millions of doses of vaccine administered is as nothing when Covid kills thousands daily.

In fact, we already did it with the flu vaccine , which many get every year. I never did. I may do it when I am much older and more vulnerable, but not now. Why is then the rush to vaccinate all the earth population , when most do not need it? To finance research and the meds companies? This is a dangerous and one way ticket to a potential major disaster. Stop being a herd.

She told me they alter your DNA and no one knows the long term effects of changing your DNA. Also, she claims some US agency had to change the definition of "vaccine" in order to allow them to be made. Can anyone tell me how to refute what she believes? Any good and trustworthy sources to counter this line of thinking?

    • Your mom might be on to something. The truth is that there are zero studies on long-term health consequences of these rush-to-market, experimental, novel mRNA-based vaccines. Also, notice that in the medical definition of the word "vaccine" the words "cure" or "heal" are no where to be found. The only specifically STATED medical goal is the creation of anti-bodies. And when you look up anti-bodies and break it down to simplest form, it means anti-life or destroyer of life.

    • What a vaccine is has changed over time. Originally, it referred to the specific method of using the cowpox virus to provide immunity to smallpox. It's where the name vaccine was derived from, based on the scientific name for cowpox. Later, we started using weakened forms of the virus to provide immunity and those were called vaccines. More methods were developed over time, but the overall idea of vaccines is unchanged. They provide something for the body to train for against a future infection. The viral vectors and mRNA vaccines all do that. Definitions change all the time.

  • It's scary that we are putting this in so many people when it was developed so recently and we don't know what the long-term implications are.

    • @eyescreamcake That would mean closing the most essential of infrastructure like grocery stores, where crowds of people can unavoidably build up. You can avoid as many people as you can, but know that one can never be careful enough. If you're worried about the mRNA vaccine, keep in mind that the same mechanism involved after vaccine administration also happens whenever you contract more common viruses like the Influenza virus, which is one of the known RNA Viruses. Your last response to Sheputster is also a very good point, by the way. 👍🏼

    • @Sheputster Haven't countries always banned people from entering if they haven't been vaccinated? They have every right to keep infectious disease out of their land.

    • @M. Alb Because we can avoid COVID by just avoiding people? Or by getting conventional vaccines that have been proven by decades of use?

    • @Sheputster You're accusing me of moving goalposts now? Alright, let's reformulate it then - why can't you stand not travelling and visiting certain businesses for a short while? You pretty much failed to grasp some of the context in which obesity, compromised immune systems, diabetes, hypertension do not necessarily cause life-theatening conditions by themselves in such a very, very short period of time.

    • @M. Alb Nice goalpost shift. The vaccine passport isn't just about traveling, it may also limit your ability to shop at certain businesses and routinely commute state to state. You're also vastly exaggerating the effects of COVID, and if you didn't know, the "500 thousand dead" the media likes to seethe about consists mostly of overweight, immunocompromised 60 year olds+ wherein COVID itself was a contributing cause of death.

  • I have only one question. How long will these vaccines protect a person? Why is nothing said about it.

    • @No Name This is the first time I hear such information about 6 months. Is this official information? Brand new vaccines, and you're talking about the past 6 months. Where does this data come from?Do you have similar information about other vaccines like Astrazeneca, Sputnik V..You аrе talking only about Pfizer vaccine.

    • We won't know for sure how long they'll last until that amount of time has passed. So far the BioNTech one is effective 6+ months.

  • My biggest question is how long does a vaccine keep us protected and how long is it effective for I got mine this Tuesday the Moderna and I’ve always wondered how long it’s going to protect me or work for

    • The BioNTech vaccine so far is at least 6 months. We won't really know until X amount of time passes. We have to wait in real time. The Moderna vaccine is likely to have a similar length of effectiveness since it use the same tech as the BioNtTech one.
