Large Antibody Study Offers Hope For Virus Vaccine Efforts (apnews.com) 62

Antibodies that people make to fight the new coronavirus last for at least four months after diagnosis and do not fade quickly as some earlier reports suggested, scientists have found. From a report: Tuesday's report, from tests on more than 30,000 people in Iceland, is the most extensive work yet on the immune system's response to the virus over time, and is good news for efforts to develop vaccines. If a vaccine can spur production of long-lasting antibodies as natural infection seems to do, it gives hope that "immunity to this unpredictable and highly contagious virus may not be fleeting," scientists from Harvard University and the U.S. National Institutes of Health wrote in a commentary published with the study in the New England Journal of Medicine. One of the big mysteries of the pandemic is whether having had the coronavirus helps protect against future infection, and for how long. Some smaller studies previously suggested that antibodies may disappear quickly and that some people with few or no symptoms may not make many at all. The new study was done by Reykjavik-based deCODE Genetics, a subsidiary of the U.S. biotech company Amgen, with several hospitals, universities and health officials in Iceland. The country tested 15% of its population since late February, when its first COVID-19 cases were detected, giving a solid base for comparisons.

  • If they are the right ones and not 'suboptimal' ADE.

    • They may be right for SARS-COV-2, but enable ADE for different strains -- which seems fairly unlikely to me. Coronaviruses can rarely take advantage of ADE but I'd be more concerned if it was a flavivirus. Anyway ADE is another reason why a rationally designed vaccine would be better than the nonsensically trying to create "natural herd immunity" in a population by allowing people to get infected with the virus. A vaccine design can try to avoid using target epitopes that might be susceptible to ADE at the

        How convenient this should be announced 60 days before the next election. Without any evidence to substantiate the claim.

        But the really good news is based on current models, if people stop wearing masks, we could potentially see 3,000 dead each day [cnn.com]. This would mean over 400,000 dead by the new year. If we want to go the herd immunity route, over 600,000 might die in the same time.

        Possibly even better news, the Midwest is seeing a spike in cases [nationalreview.com]. We've already seen the first death related to Sturgis [thehill.com] so more are bound to happen.

          If people stop wearing masks? Why all of the sudden would people stop wearing masks? If we maintain mask/distancing compliance that we currently have, daily deaths will likely continue to drop from the current ~1,100 - 1,200 per day. Trotting out some unlikely scenario to try and scare people is nothing but fear-mongering.

          We've already seen the first death related to Sturgis [thehill.com] so more are bound to happen.

          So almost 500,000 people attended a 10 day motorcycle rally where it has been reported that few wore masks...and there's less than 300 known cases and one dead from COVID? Those number

          Did you see the announcement that only 6% of those they're claiming are covid-19 deaths are actually from just covid-19? So this moves it right into the seasonal flu category. All the others were going to die anyway - old, had cancer, etc. So this is purely political by the left.

      While it is good news, I wouldn't be dancing unmasked in the street. These things take time, even with the accelerated interest in finding a vaccine, it will take a while before we can get our shots.

    • I thought I had caught Covid-19 (I sure got plenty sick with very high fever, and so did everybody in the household, it was also short-lasting and we all had terrible coughs for weeks afterward). After 4 months I had an antibody test and it came back negative. That was bad news, sounds like I did not have it and thus could still get it. Then the news started to arrive that the antibodies disappear in a short time. That was good news because it meant I could have had it. Now this is saying that is not true a

      • It's entirely possible that both things are true: The antibodies you were tested for had faded away after a couple of months, but the antibodies this study looked for (and you weren't tested for) stay around longer. Most of the widely available antibody tests so far have looked at only one type of antibody, and those tests were verified using blood taken from patients a couple of weeks after infection when that particular type of antibody was at its peak concentration. This study appears to use a set of six

        Negative results don't generally mean a lot.

          It was a vein blood test. But you are right, to be honest I am pretty certain I got it, and that if I did it is extremely likely I am immune to it. The virus is not much different from others that the immune response to is well known and works. Just that I was rather disappointed that the antibody test did not show it.

    • Antibodies will only help so far. They won't stop you from getting one of the several mutations of the strain circulating. Just ask those in China.

      Your homework for today is to figure out what about this statement doesn't make sense.

    • The human body has more than just antibodies to fight viruses. You can have immunity long after antibodies have faded.

    • by spitzak ( 4019 )

      The antibodies will still work with a lot of mutations. The mutation has to actually change the part the antibody recognizes. Also it seems like the effective antibodies attach to the portions of the virus used to breach cells, so a mutation that makes the antibody not work will also likely stop the virus from working too.

    I understand that the scientific method has to run it's course, and that viruses can throw us surprises, but I never believed for a second that our species might be unable to develop a long-term immunity to COVID-19.

    This class of viruses has been around for about 50 million years (estimated). So, the VERY FIRST HUMAN was fighting coronaviruses. By the time we showed up on the planet, our ancestor mammals had already been adapting to them for about 45 million years. Chew on that for a minute. The possibility that we somehow have no ability to fight off something in this viral class? Absolutely ZERO. Any individual that weak to coronaviruses was put put out to pasture a long, long time ago. Evolution is brutal and effective.

      Just like our species has developed long-term immunity to the common cold and other viruses?
    • Anything that doesn't kill off 90+ percent of the human population will be survived by mankind, and in a couple of hundred years, people would barely mention it. The survivors though, will mention it daily until their natural deaths. And perhaps not in good health. In terms of Covid19, no one fears for the future, but for the lives and well-being of mankind at this moment.
  • Although this is good news, here's the actual finding:

    "In a subgroup who tested positive, further testing found that antibodies rose for two months after their infection initially was diagnosed and then plateaued and remained stable for four months."

    They are not claiming permanent protection, but even 6 months would be pretty good.

    • Yeah if need be I could get a shot every 6 months. Yearly would be better, but 6 months is still within the realm of practicality. If it was a matter of "you're going to need to get a booster shot every 3-4 weeks" then that wasn't going to be effective.

    • by dwywit ( 1109409 )

      Wouldn't repeated exposure to the virus keep stimulating production of the antibodies?

      Just because you've had it once and recovered, doesn't mean you'll never be exposed to the virus again - it's here to stay.

    This has become politicized so 3/4 of the population of the US will refuse the vaccine. Just got a super worried email from my mother about "OMG don't take the vaccine Trump rushed it through, we'll all die!!?!!". The usual anti-vaxxer tards also won't take it for the usual reasons so now you have a ton of people that will refuse to take it.

    Personally, I will see what the data says about it, how it was tested, and historic safety data for similar types of vaccines. I won't refuse to take it simply because Orange Man Bad (which he literally is, I agree).

    • The worst thing that could *probably* happen with the vaccine, is that it does not work. They are finding out nobody is asymptomatic, you are only pre. Long-term damage includes the lungs, kidneys, liver, heart and/or brain.

      It will be interesting to see if there are significantly different outcomes in those two groups. My suspicion is that the folks who think that it is being rushed will continue to stay locked down while the essential workers get the shot and beta test it for them, while the anti-vaxxers will refuse to take it and will go on with their lives, and a decent number of them will die from it.

      Arguably, folks staying locked down longer and refusing the vaccine will actually be a good thing in terms of the case coun
