Moderna COVID-19 Vaccine Shows Promising Result In Animal Tests (bloomberg.com) 103

Posted by BeauHD from the promising-results dept.
Moderna's vaccine candidate against Covid-19 protected against the virus in a trial that inoculated 16 monkeys, an encouraging step on the path to a defense for humans against the pandemic. Bloomberg reports: Two injections of the vaccine protected against heavy exposure to the virus at two different levels of dosage, Moderna said in findings published Tuesday in the New England Journal of Medicine. The primates didn't show any sign of creating enhanced disease, a problem that has occasionally been associated with vaccines. The results, if they hold up in humans, suggest that the vaccine may be able to protect against Covid-19 in both the upper and lower airways. In all the monkeys who got the high doses of the vaccine, no viral replication was detectable in their noses two days after being challenged with the virus, according to the study results. And no viral replication was seen in the lung fluid of 7 of 8 animals in both dose groups after being challenged with the virus. All 16 monkeys showed at least some sign of protection, with limited lung inflammation seen in the lungs of both groups. The report says that the phase 3 trial, which involves 30,000 humans, will begin producing data in November or December.

    I wasn't familiar with this term so I looked it up:

    Antibody-dependent enhancement (ADE), sometimes less precisely called immune enhancement or disease enhancement, is a phenomenon in which binding of a virus to suboptimal antibodies enhances its entry into host cells, and sometimes also its replication. This phenomenon—which leads to both increased infectivity and virulence—has been observed with mosquito-borne flaviviruses such as Dengue virus, Yellow fever virus and Zika virus, with HIV, and with coronaviruses.

      Antibody-dependent enhancement (ADE) could explain much of what goes on with COVID-19 and why some people spiral off in increasing pathology.

      Basically what happens is that antibodies bind to a virus, and the resulting blob fits a different receptor on certain white blood cells, called Fc gamma [wikipedia.org]. This means that a virus that is not specific to this receptor (e.g. SARS-CoV-2 which binds to the ACE2 receptor) can now enter cells other than its usual ones. The white blood cell infection causes more viral replica

    I thought there were 12.

    • Let them die from it, or at least suffer lung and heart damage. It's too crowded already.

  • The Chinese and Russians will have a vaccine out sooner by allowing volunteers to deliberately expose themselves to the virus and other related coronaviruses (to check for enhancement). It's wise to check for enhancement with similar strains, not just the targeted strain. Anyway that's two things we oughta be allowing volunteers to do (deliberate viral challenge) in my opinion.

    Of course where they F up is that some of the Russian and Chinese vaccine candidates use adenviral vectors .. not a great idea when

    • Beyond coronavirus, I think China is going to be a major, or "the" major world force in medicine. The pace of medicine is governed primarily by two things: how much money you can invest, and the risks you are willing to take.

    • I suspect the Chinese or Russian vaccines will be the only ones I could have any chance of being able to afford. Pity since they will probably turn one into something like a giant bioluminescent land-squid with a life span of only 1 year.

          Why would it be too expensive? If you have health insurance then it would probably be free, like most vaccines. If not, it should be around the same cost as a flu vaccine, which you can get at walmart for like $30 (and they sometimes give you $10 to spend in store).

          • Because they can. Shingles is a couple hundred and depending on your health insurance may or may not be covered. I doubt mine would, it is a high deductible plan. I just checked, HPV vaccine is also around 250. So yes, it would be good if the US just bought it and delivered it for free to ensure herd immunity. Heck the US has already given massive amounts to the drug companies for the research to bootstrap this thing. Why not finish the job?

            • Good examples because that is way beyond what I could afford. That is close to my monthly income. Almost no one in the country where I live could afford those vaccines. Given the global emergency and massive demand I would expect to see at least double those prices if not more.

          • I don't have health insurance. I live on the other side of the world from the US. I could afford $30 I suppose, but I think it is going to cost a lot more than that. This has a higher value than a mere flu vaccine that only works about 50% of the time anyway. I wouldn't expect them to set a similar price, but I guess we will see what sort of price they set. If it's $999 per dose I would not be too terribly surprised. Especially since most Americans have health insurance. So for the employed it is usually on

            • I sent this insurance to hell long ago. It is useless where the presence and assistance of insurance companies is really required and is certainly useless while you are relatively healthy. I can buy vitamins and aspirin myself, as well as such herbal medicines - https://purekana.com/products/cbd-muscle-menthol-roll-on-gel-3oz-600mg/ [purekana.com] It costs me less. I see no reason to pay for an untested vaccine with a high risk of complications. I'd rather strengthen my immune system.
        • There's already a deal in place where the US government will purchase 100k doses and supply them for "free." Meaning we'll pay for it through taxes.

      This vaccine is in phase 3 human trials now. It will be tested using 30,000 volunteers. https://www.nih.gov/news-event... [nih.gov]

    • It was tested on animals, and the company that developed the vaccine has now published the data and analysis from those tests. It's not as if medical researches publish their data in journals the day after they collect the data.

      The Phase 3 clinical trial for the vaccine started this week.

    • You're confused. There are over 200 vaccines developed, 3 look promising. Maybe none of those 27 pass.

    • Because it is not a 100% guarantee that those other 27 vaccines pass clinical trials. Hopefully one of them does but this is another promising candidate. Also this vaccine might be more effective.

      The same way that many of those creatures, that treat each other well, kill an eat animals other than their kind.

          So what is your proposed solution? Do long-term testing on people who are so much less worthy than you? What do we do in the meantime (you mentioned 'a few decades')? 'Live' like we are now, locked up in our homes and treating every passing encounter with another human as a potential death sentence (except, of course, for the people less worthy than you that do things like provide you with food). Or maybe just ignore it altogether - no risk in that, right?

          • Part of my "suggested solution" would be the frigging TRUTH. That this is an illness that almost exclusively targets those with weak immune systems. That has not been known to be problematic in anyone else. And to publicize known and uncontroversial facts such as the role of adequate levels of vitamins C, D, and zinc, in preventing and minimizing the impact of viral illness in general. That would save many, many lives, without harming anyone.

        • In the general, vaccines have not been 'very problematic' in the past. We routinely inoculate millions with a level of side-effects that are so low as to be hard to separate from unrelated phenomena that happened to be co-temporal.

          In the specific, certain vaccines for things like exotic bioweapons and swine flu have involved side effects, but still at a level less than the risk of what they were protecting against.

          If you believe things are significantly worse than the above, then you've been lied to by what

          • In general I'm not against vaccines, as long as they haven't been tested on animals. But there are grave examples where vaccines have ruined peoples lifes, swine flu vaccine has given people narcolepsy is one such example.

            • The number of narcolepsy cases is lower than the expected number of deaths from swine flu at the time the decision was taken to give the vaccine. So even in that sad case, the numbers supported vaccination. And narcolepsy is easier to live with than death.

              I'd never argue that vaccination is without risk, and there are those who honestly can't take vaccines for a range of medical issues - and the rest of us have to provide protection to them by doing so. I just wish more people would assess the risk accurate
