India's DNA COVID Vaccine is a World First -- More Are Coming (nature.com) 167

India has approved a new COVID vaccine that uses circular strands of DNA to prime the immune system against the virus SARS-CoV-2. Researchers have welcomed news of the first DNA vaccine for people to receive approval anywhere in the world, and say many other DNA vaccines may soon be hot on its heels. From a report: ZyCoV-D, which is administered into the skin without an injection, has been found to be 67% protective against symptomatic COVID-19 in clinical trials, and will likely start to be administered in India this month. Although the efficacy is not particularly high compared to that of many other COVID-19 vaccines, the fact that it is a DNA vaccine is significant, say researchers. It is proof of the principle that DNA vaccines work and can help in controlling the pandemic, says Peter Richmond, a paediatric immunologist at the University of Western Australia in Perth. "This is a really important step forward in the fight to defeat COVID-19 globally, because it demonstrates that we have another class of vaccines that we can use."

Close to a dozen DNA vaccines against COVID-19 are in clinical trials globally, and at least as many again are in earlier stages of development. DNA vaccines are also being developed for many other diseases. "If DNA vaccines prove to be successful, this is really the future of vaccinology" because they are easy to manufacture, says Shahid Jameel, a virologist at Ashoka University in Sonipat, India. The urgency of combating COVID-19 has fast-tracked the development of vaccines that use genetic technology, such as messenger RNA and DNA vaccines, says David Weiner, director of the Vaccine & Immunotherapy Center at the Wistar Institute in Philadelphia, Pennsylvania. RNA vaccines were quicker to show strong immune responses in clinical trials; they have now been delivered to hundreds of millions of people around the world. But DNA vaccines have a number of benefits, because they are easy to produce and the finished products are more stable than mRNA vaccines, which typically require storage at very low temperatures.

    A number of experimental techniques like RNA and DNA vaccines which were being developed for cancer were moving slowly as people werent sure about the side effects. Now we have had an emergency situation so the FDA allowed these to go ahead because of the cost benefit analysis. Now we have safety data from millions of doses and it seems these approaches are not as risky as thought earlier. Now that we know the approach works and is safe, we can go full speed ahead with cancer vaccines.
    • except the hero blows himself up but lives in the fake news version.

    • it seems these approaches are not as risky as thought earlier

      And yet, our society remains ever primed towards questioning the basic safety of novel approaches involving well-understood science, but ever-accepting of "alternative cures" involving very questionable substances with absolutely minimal scientific evidence of their effectiveness in such scenarios.

      I literally hope the alt-right conspiracies start promoting embalming fluid as their next alternative cure. At least that way, those people will be pre

        The way cancer vaccines work is they take a sample from your tumor and create a RNA fragment which is tailormade to that particular tumor. Inject the rna and your body creates antibodies which attack that tumor and nothing else. It can be used for tumors in inoperable locations. In theory it can reverse Stage 4 tumors. Practice has been moving slowly as scientists have been worried about what else an RNA fragment will do in your body. But the millions of doses of RNA vaccines given without any major complic
  • We already have systems that look for DNA that is not in the nucleus of our cells and destroy it.

    There also isn't a system in our body that imports DNA into the nucleus of our cells. Viruses that do that (such as chicken pox) have to make their own protein to do it.

    • The fact that people are shouting it for RNA doesn't bode well for anything DNA based. Plus the "easy to manufacturer" isn't much of a selling point when a large number aren't even taking what's currently available.

      • The main benefit on the "easy to manufacture" front is this doesn't need cryogenic storage, since DNA is more stable. So, don't need to keep it as cold while you're making it or shipping it.

        It should help in all the places still clamoring for vaccines but can't get enough of them do the the difficult logistics of mRNA vaccines.

      • a large number aren't even taking what's currently available.

        This is a first-world problem.

        In developing countries, there are still dire shortages of vaccines, and many, many people are willing to take them.

        If we are going to beat this disease, we need worldwide herd immunity.

        DNA vaccines are a good solution for developing countries because they are cheap and easy to transport.

        • >"If we are going to beat this disease, we need worldwide herd immunity."

          Define "beat this disease."

          We will have worldwide herd immunity, regardless of what we do. What we do might speed it up, slow it down, or affect how many get sick or die in the process, however.

          • We will have worldwide herd immunity, regardless of what we do.

            That will only happen if the vaccination rate stays ahead of the mutation rate.

            • >"That will only happen if the vaccination rate stays ahead of the mutation rate."

              That is assuming that natural immunity has zero (or little) effectiveness against variants. And I don't believe that is true (I doubt you believe that either). If it were true, the human (and other species) would never have survived through the millennia.

      Sure, a DNA vaccine might not change change your genes, but it will give you great 5G reception!

    DNA vaccines have a number of benefits, because they are easy to produce and the finished products are more stable than mRNA vaccines

    ZyCoV-D contains circular strands of DNA known as plasmids, which encode the spike protein of SARS-CoV-2, together with a promoter sequence for turning the gene on. Once the plasmids enter the nuclei of cells, they are converted into mRNA, which travels to the main body of the cell, the cytoplasm, and is translated into the spike protein itself. The body’s immune system then mounts a response against the protein, and produces tailored immune cells that can clear future infections. Plasmids typically degrade within weeks to months, but the immunity remains.

    It sounds like these are really just a cheaper and more stable way of packaging mRNA vaccines... but I'm no biologist.

      You are correct except for the word "just".

      With 4 billion people still not vaccinated, a cheaper and more stable vaccine is profoundly important.

        these DNA plasmid rings are WAY too small to be resonant to 5G frequencies, this will never work. You'd have to tailor them to resonant at some thousand-fold (or more) harmonic frequency. There's no way these can turn your aura indigo, unless you use a triple-strand MÃbius DNA loop. It's simple Teslamatics, any 5-year-old can figure this out! Hell, Gene Rodenberry knew all this Rife resonant frequency SCIENCE in the 60's when he invented the tricorder!
    • Well, they're an RNA precursor.

      If it produces an immune response, it's somewhere in the same chain of events. Of course. That's true all the vaccines.

        Pretty sure using pepper/bear spray provides a better outcome for society. Furthermore, if you dose these people with vaccine w/o their knowledge and they then don't ever get sick, it will just reinforce their belief that they don't need vaccines ...

          At this point we are wearing masks just to protect children under 12 and anti-vaxxers.

          Once Children 5-12 are vaccinated I am not going to wear masks to protect anti-vaxxers.

          I am vaccinated so if I become infected and an asymptomatic carrier the only people at risk are anti-vaxxers.

          I will not inconvenience myself to protect anti-vaxxers.
          • You're also doing it to protect a small percentage of the population who can't be vaccinated for legitimate medical reasons. But even if not for them, your plan still wouldn't work because the anti-vaxxers would overwhelm the healthcare system and cause collateral damage that way. Plus they'd eventually bring a new, more dangerous variant into the world.

            • by ghoul ( 157158 )
              Thats a bullshit argument. Immunocompromised people have been living in a society with hundreds of viruses and we didnt go around wearing masks to protect immunocompromised from the Chicken Pox or Polio. They will deal with it the same way they have dealt with other risks of infection. These are excuses to protect anti vaxxers from their stupidity.

            There are still breakthrough infections and yes, people have died from those. Don't wear a mask at your own risk. Or don't wear one because if you get a breakthrough infection, you'll be wanting to spread it to as many others as possible.

            Oh, there is now the mu-variant and we aren't sure how well vaccines work on it. Actually, there are also several other variants.

              There are breakthrough infections with every virus and every vaccine. I am vaccinated against measles. There are breakthrough infections in measles as well. I dont recall wearing a mask for the last 40 years to avoid measles. At this point in Covid people are just habituated to wearing masks. Its like a comfort blanket. Scientifically speaking its not justified if you are vaccinated.

                At this point. There are still millions of infected people in America spreading COVID. When the prevalence is as low as Measles. Then you get to treat it like Measles.

                  The solution is to mandate Covid vaccines like measles vaccines are mandated. Not to go around wearing masks.
                  • The solution in a sensible country yes.
                    When everyone has been vaccinated and the COVID prevalence is as low as Measles, sure.

                    Do you expect the people crying about having to wear a mask are going to be happy letting you inject things into them. They have too many FREEDUMBS to put up with that.

          • >"At this point we are wearing masks just to protect children under 12 and anti-vaxxers."

            We don't need to protect either. People who don't want to take the vaccine a free to spin the wheel, that is their choice. Children without severe underlying conditions are statistically not at risk regarding COVID-19, never have been. Those with such conditions have always been at risk for ANY type of infection; and pathogens are not going to disappear, ever.

            Plus, non-N/K95 masks do little to stop COVID-19 spread

        And they prefer "natural immunity" anyways, so I say we give it to them all at once and get it over with in a few weeks. If they get really sick, we can put them in the sportsball stadium where they can all pray together. They will get the salvation their God wants them to have, guaranteed.

      Actually pregnancy and immunity have weird interactions. During pregnancy a woman's immune system has to ignore what is basically a parasite with foreign dna growing inside the womans body. Whether vaccines work for pregnant women needs separate studies other than those done for the general population.
