If Bird Flu Jumped to Humans, Could Past Flu Infections Offer Some Protection? (npr.org) 201

NPR reports on research "into whether our defenses built up from past flu seasons can offer any protection against H5N1 bird flu." So far, the findings offer some reassurance. Antibodies and other players in the immune system may buffer the worst consequences of bird flu, at least to some degree. "There's certainly preexisting immunity," says Florian Krammer, a virologist at Mount Sinai's Icahn School of Medicine who is involved in some of the new studies. "That's very likely not going to protect us as a population from a new pandemic, but it might give us some protection against severe disease." This protection is based on shared traits between bird flu and types of seasonal flu that have circulated among us. Certain segments of the population, namely older people, may be particularly well-primed because of flu infections during early childhood.

Of course, there are caveats. "While this is a bit of a silver lining, it doesn't mean we should all feel safe," says Seema Lakdawala, a virologist at Emory University's School of Medicine whose lab is probing this question. For one thing, the studies can't be done on people. The conclusions are based on animal models and blood tests that measure the immune response. And how this holds up for an individual is expected to vary considerably, depending on their own immune history, underlying health conditions and other factors. But for now, influenza researchers speculate this may be one reason most people who've caught bird flu over the past year have not fallen severely ill....

Research published this month is encouraging. By analyzing blood samples from close to 160 people, a team at the University of Pennsylvania and the University of Chicago were able to show that people born roughly before 1965 had higher levels of antibodies — proteins that bind to parts of the virus — which cross-react to the current strain of bird flu.

This week U.S. federal officials also "announced funding for avian influenza research projects, including money for new vaccine projects and potential treatments," the Guardian report. The head of America's agriculture department said it would invest $100 million, as part of a larger $1 billion initiative to fight bird flu and stop rising egg prices, according to the nonprofit news site Iowa Capital Dispatch.

    But the current administration is just batshit insane and they're not expecting to have elections in 2 years let alone four so they aren't just under funding vaccine development they've shut it down entirely.

    If we get hit with a serious case of bird flu it's going to be three to five times more lethal than COVID at a minimum and we are going to be in much much worse shape politically and scientifically.

    I suspect we'll lose about 15 to 20% of the population. I guess the survivors will thank us...

        If everyone understood the science of vaccines and got vaccinated its just that plain and simple but well here we are.

        COVID was not started by a lab leak and vaccines are ultra safe and ultra effective. Only right wing nutbars doubt that.

        Also, Abortion is a form of medical care. The American civil war was fought over slavery. I am tired of arguing these points with people who refuse to acknowledge reality. If you're a Republican vote or you're either somebody who is extremely low information, has stepped away from reality, is a psychopath, always just so bitter and angry that you want to burn the whole world down for the sake of it. They're digging up tons of minor side effects reports and claiming the vaccine should be pulled because of that, and not the real reason. There absolutely no known side effects to vaccines.

        But sometimes you just don't want to do business with someone because they're kind of an asshole and Spotify is being more than a little bit of an asshole by allowing Rogan to spout off anti-science and anti vaccine propaganda that's going to get people killed.

        A lot of your compatriots aren't getting vaccinated against COVID. Sure, it won't kill them thanks to anti-virials, but the hospital stay will end with permanent heart & lung damage. So a bad day turns into a stroke, a stroke a heart attack and a heart attack ends with, well. So we have large swaths of people who aren't going to get vaccinated.

        Vaccines are safe and work. It's like arguing both sides on eating dog poop. It's no different than the gov't telling you not to eat tide pods.

        Donald Trump deregulated food safety during his first term. Joe Biden tried to restore the regulations but the courts blocked him. Courts that were packed with Trump appointees. So yeah Donald Trump is directly responsible for the price of eggs being high. And they're going to get much more expensive. At least for a little while. When H1N9 finishes mutating and we have no vaccines and no preventative measures it's going to kill about 30% of the population at least. Possibly as much as 50%.

        Biden did hand out 600 million to make vaccines though. We won't be caught completely off guard like we were last time. Probably that is. Again we're a simple mutation away from a disaster and we've got a 78-year-old man who couldn't get through a 1 hour town hall between us and that potential disaster. All Trump did with regards to the COVID vaccine was signed the checks and it wasn't even his money. It never is.

        People do go looking for content creators and there's tons of them spreading misinformation especially about things like vaccines or wars or bits and pieces of national news.

        So here we are 5 years or so later and there is unequivocable proof that these miracle cures were bullshit but I can tell you right now that's just like how when the link between autism and vaccines turned out to be made up by a guy who was hoping to sell separate vaccines for mumps, measles and rubella this will be ignored by the same people still pushing horse paste as a cure all.

        I found out recently I wasn't vaccinated against Measles. My mom was an anti-trans nutter and I suspected so I got checked. Polio is harder. I haven't been able to find a lab that can test me. But I haven't heard that either. What I have generally heard is that Brazil is upset that Elon is refusing to take down actual misinformation like anti-vaccine misinformation or the kind of stuff that inflames riots. A whole bunch of factually incorrect lies about vaccines is publsihed.

        But it is absolutely galling to have the word censorship used in regards to anti-vaccine misinformation being removed from websites. The word censorship has a very specific connotation in American English. And that does not fall under it. We learn that the hard way when one of his charities blocked one of the covid vaccines from going into the public domain (The moderna one I believe). If you're old enough to know the history of the polio vaccine that should be especially galling.

      With the egg shortage sure to get worse if bird flu continues to get worse, the best vaccines will be the mRNA ones, which will surely get the most ire from the wingnuts. On the other hand, if the vaccine is widely available by some miracle despite the gutting of scientific support in this admin, it'll be the most politically polarized epidemic ever as far as impact. Masks will work better for flu than they did for COVID, too, so it'll be a wild ride.
    • Yup, the article and the science behind it are simple reminders to go get the jabs.

      They're not 100% effective, some people still get sick, this has always been true. Some years lots of people get sick. But that's not what efficacy is about.

      If you get the jab you are less likely to get sick, not guaranteed not to get sick. If you get the jab and also get sick, you are much less likely to have a severe illness or be hospitalized. Even if you get sick, you get some amount of protection because you've exerci

        The flu shot didn't seem effective this year - those who got the shot, but got the flu were still knocked out for a week, and a month or two later, still had symptoms.

        But it does beat getting it where apparently people can be knocked out for weeks to months and even at the end, still are feeling really bad.

        I had the flu once, it knocked me out for a few days (I was so bad work actually sent me home). But then I never really recovered and was hospitalized a few months later for a week with a heart condition

          BUT
          They have to guess every year at which strains they have to worry most about and some years they fail, but there is almost no acknowledgement of this in reporting and of course there is none in advertising. But if you google around you can find info on which strains they targeted, and whether those strains are actually the problem, so you can determine whether or not it's actually worth getting the shot.

      You're probably overstating the case. I remember the bird flu of the 1970's, and it was BAD. But I didn't hear about lots of people dying. (OTOH, part of the time I was so sick I might not have noticed if someone died. Yuck! Well worth avoiding at considerable effort. I seem to recall going unconscious half-way to the bathroom after spewing my guts from both ends.)

      • >"I remember the bird flu of the 1970's, and it was BAD. But I didn't hear about lots of people dying."

        Different flus are different. But another huge factor is- how many grossly overweight people did you see in the 70's? How many people had diabetes? These are huge risk factors for dying from infections that would not normally be deadly. We saw a lot of that with COVID-19, as well. The super-majority of those who died had lots of pre-existing health complications and major risk factors.

      Im kind of hoping that being in a building with actual adult and sane virologists and epidemiologists , some with significant experience in science communication, might buffer some sense into RFK.

      My impression of him is that he's not an unreasonable man , he's just dumb as a bag of hammers. And my experience with folks like that is you can usually reach them with patience (I had a bunch of elderly relatives refuse covid vaccines because the shouty man on fox news said it would hurt them. But I spent time with them, and my GP ex girlfriend (who they all adore) explaining carefully the whole picture, and they are now all vaccinated. The only one i couldn't reach was my teethgrinding idiot cousin whos deep deep in the thrall of QAnon and MAGA conspiracy theories and yeah, SOME of those folks are beyond reach.

      But my take on RFK is he just seems like a friendly imbicile. I think he can be reached.

    I am dismayed that a virologist would say such things, as I would expect them to know better. The truth is that we simply do not know. There is insufficient evidence to predict whether or not the current human population has any clinically significant immunity to this H5N1 subtype. We do not even know whether or not it will mutate to become more transmissible from human to human.

    Yes, there are some basic principles at work that might suggest that preexisting infections and vaccinations for human influenza could confer some degree of protection. But that's such a broad and superficial notion--it doesn't convey any sense of the extent of protection, if any. The 1918 flu pandemic ("Spanish flu") that killed millions of people, of course did not occur in a totally immunologically naive population with respect to human influenza, so what justifies any assertion that our existing exposure to human influenza will confer protection against H5N1 in any meaningful way?

    In any population there will be intrinsic variability in which some people will be more susceptible to worse clinical outcomes, and others who will be less susceptible. We do not yet know who these people are, because this disease is not yet pandemic or endemic. We still don't even know who these people are for COVID-19, which has become endemic. I would have thought that especially among the scientifically literate, people would have learned something from the COVID-19 pandemic with respect to making predictions or assertions about the behavior and impact of infectious diseases on a population. I've long since given up on the general population learning anything. But I am deeply disappointed that a virologist would speculate on such matters, as the message inevitably becomes further distorted by journalists and then politicized and warped beyond all recognition by a self-absorbed and uneducated public.

      Especially since most sniffles are viral in nature, or allergies. No point in taking antibiotics for that.

    • It's - btw. - the exact reason I avoid taking antibiotics for every little sniffle I catch.

      As sibling said, antibiotics don't work on viruses, or have little effect.

      Antibiotics also have adverse effects every single time you use them, unlike vaccines. They always cause unintended effects. Notably, they affect the balance of our internal biota. Then people exacerbate this by consuming sugars at their natural rates, which is well known to feed the undesirable bacteria more than others, so they are killing off the worst stuff while feeding the bad. And to add injury to injury, have you seen hospital

    Maybe some, but not a lot. It just doesn't work that way. Prior work will apply to some degree, but a new vaccine would need to be developed.
