    Meeting to address bird flu research impasse: WHO
    The Canadian Press
    Date: Saturday Jan. 21, 2012 4:23 PM ET

    The World Health Organization will gather a relatively small group of technical experts in mid-February in a bid to try to breaking the impasse over the proposed publication of controversial bird flu research...

    ...A senior official of the Geneva-based WHO says the meeting will likely involve fewer than 50 people and is tentatively slated for Feb. 16 and 17, though the dates may change...

      Scientist Plays Down Danger of Flu Strain

      By DONALD G. McNEIL Jr.
      Published: January 25, 2012

      A Wisconsin virology team that created a more contagious form of bird flu did not produce a highly lethal superflu, as a Dutch team famously and controversially did last year, according to the leader of the Wisconsin team.

      Dr. Yoshihiro Kawaoka of the University of Wisconsin-Madison and the University of Tokyo said in a commentary published online by Nature magazine that his team?s virus had infected ferrets through the air, but that it did not kill any of them. Ferrets catch flu just as humans do. Also, he said, ?Current vaccines and antiviral compounds are effective against it.?

      By contrast, a virus created by Ron Fouchier of Erasmus Medical Center in the Netherlands had both the high lethality of the H5N1 avian flu and the ability to transmit easily among ferrets, touching off fears that his virus could be devastating in people.

      However, a flu expert who serves on an American scientific advisory panel that looked at both Dr. Fouchier?s work and Dr. Kawaoka?s said the panel still believed key details should be censored from both papers before they are published to keep terrorists or rogue scientists from being to replicate the work, since the gene-manipulation techniques and intermediate mutations are as potentially dangerous as the end products.

      Some scientists believe that Dr. Fouchier created what is potentially the most lethal virus in history ? a flu that would transmit through a sneeze and kill more than 50 percent of those who caught it. That has led to calls for restrictions. Some ? including the editorial board of The New York Times ? have argued that the virus stocks should be destroyed; others want the virus restricted to a small number of laboratories with the highest biosecurity levels.

      Some scientists, including Dr. Fouchier, argue that the fear of his virus is exaggerated. What works in ferrets does not always work in humans, they argue, and the true lethality of avian H5N1 is unknown because there have been fewer than 600 confirmed human cases and many milder ones might exist...

        so Kawaoka et.al took the HA from H5N1 and reassorted
        it with ******, the result was highly transmissable
        among ferrets but no more virulent than ******.

        If that works the same way in humans then we could
        maybe cause an artificial mild H5N1 reassorted pandemic
        and thus get immunity towards other lethal H5N1 strains.

        But it opens the door for further reassortments that
        could make it lethal again.

        And we could get that strain or similar combinations in swine,
        if it were really that transmissable.
        H5N1 were endemic in Indonesian swine in some regions,
        causing only mild disease.
        And we know, how much flu reassorts in swine recently !

        So, terrorists,researchers just mix swine with 2009flu,
        1998pigflu,H5N1indoswine,1978euroswineflu and see
        what you get, haha.
        And if some viruses escape - das macht doch nix, das märkt
        doch keiner...

          doesn't make much sense to me.


          "fear needs to be put to rest"


          I wonder whether he has some interest in the data-release, i.e. whether he wants to
          work on the issue.

            no.These were single outbreaks, the virus died, then another outbreak
            occurred elsewhere. The current HP H5N1 is "circulating" only since
            1997. H5N2 was circulating in American poultry, but not as virulent.
            And a completely different strain in all 8 segments.

            you would better study that in seasonal flu ?!

            yes,but is that particular artificial strain so important ?

            >and has, without question, saved millions of lives.

            how to prove that ? The studies could show no big effect of vaccination
            towards life saving, afaik.
            And for vaccine production, I don't see why the data in question would
            be important.

            >Is the Case Fatality Rate for Human H5 Infections Truly Greater
            >than 50% ?

            in most human outbreaks that we saw it was. If it goes pandemic,
            what CFR would we expect ? We had the clusters in Turkey,Karo,
            the outbreaks in Tigers and so bad for the chickens+turkeys.
            The cfr in humans might well go down, but then with high
            probability (>20%,IMO) it might not.
            The subclinical infections that he mentions have other
            backgrounds, not what we would expect if it goes pandemic :
            suddenly seeing mild cases and severe cases simultaneously.
            We didn't see that before.

            >1918 H1N1

            that was different. The virus is extinct, H1 is seasonal now.
            And it's much harder to reconstruct, many mutations needed.

            Arguing that possible flu-terrorism usable info had been
            published already is no indication that it should continue.
            The question is, what would we expect in the current case ?
            This must be answered by those who know the details.

            >We know ...that the 2009 pandemic vaccine protects against
            >the 1918 pandemic virus and thus the 1918 strain is not a pandemic
            >threat at this time (48)

            thus refusing his own previous argument, that 1918 H1N1 was allowed to be
            published and thus H5N1 should be too.


            >SARS,HIV

            this is very different, not much usable for terrorism.(I hope)
            And that was 2003, since then we made some advances ...

            so simple. Just others disagree ?!?

            how much does the vaccine protect and could a flu-vaccine prevent
            a pandemic anyway ? This is very debatable and it never did in the past.
            And how much would it cost and how long take to produce it ?

            It was already ?!

            "typically" ? H5N1-experiments typically didn't show this.
            It seemed to be the exception.

            Much more infections of humans happen with other avian viruses,
            yet it usually takes decades until one is successful and causes a pandemic.

            the Fouchier-virus may qualify.
            they just wrote:

            And it did in 1918.
            But it's so slow. Nature typically needs reassortment and thus
            double-infection and then transmission of that virus.
            We can much better do that in a lab.
            Heck, they can just freeze old viruses and wait some decades,centuries
            until immunity wanes -as seen in 1977- .
            Nature seems to be unable to do this.

              do we have a quote ? Who has said this ? Fouchier ?

              ----------------------------------

              But Fouchier electrified the flu world in September when he gave an outline of the work
              at a major influenza conference in Malta.
              He told the gathering that in trying to find out whether H5N1 could acquire the ability
              to spread easily among people, he came up with a virus that spread among ferrets
              as easily as seasonal flu viruses, according to a report on the meeting in Scientific American.




              Katherine Harmon was at the meeting in Malta Sept.12 and reports:

              is it just this that Inglesby is referring to ?


              and BTW. Fouchier just only announcing this in a Malta hearing was bad, IMO.
              He should have first contacted the commission and then, -if-, announce it directly on his
              webpage in a prepared statement IMO

                Research into the bird flu virus has set off an impassioned scientific debate over its risks and benefits. Here is a sampling.

                To the Editor:
                Re ?Bird Flu Scientists Agree to Delay Virus Research? (news article, Jan. 21):

                There is great debate in the scientific and public health community about what should be done regarding recent experiments in which scientists mutated H5N1 bird flu strains so that they could spread readily between ferrets.

                Ferrets are the best model for predicting human flu transmission, so the assumption should be that this new strain would spread among humans, perhaps as easily as seasonal flu.

                Both sides in the debate deeply value public health and are seeking to diminish the dangers of bird flu. The question is whether these new experiments increase or decrease the dangers of a bird flu pandemic.

                Naturally occurring H5N1 bird flu has killed nearly 60 percent of the 583 cases confirmed by the World Health Organization since 2003. Fortunately, it has not spread effectively among people. If this engineered transmissible H5N1 strain were to escape the lab by accident or intentional act, and if it maintained high lethality while spreading as effectively as seasonal flu, it could kill tens or hundreds of millions of people worldwide.

                Those in favor of the work have argued that it will improve bird flu surveillance and vaccine development efforts. But it seems unlikely that bird flu surveillance and control programs will be substantially changed based on this research. And developing vaccines against H5N1 strains that are actually emerging in nature does not require this kind of research.

                The potential benefits of the research do not justify the potential dangers, so the research should be discontinued. While in almost all circumstances basic research should be fully disseminated in the science community, in this case the results should not be published in a way that allows them to be replicated by others. If allowed to continue, the research should be performed only in pursuit of concrete, urgent goals under international approval and the greatest possible safety conditions.

Instead of fighting over what we should have done re. the original manufacture of the virus, we should now be focusing on education, vaccines, etc... The virus mutating on its own was always a threat in any event. The virulence has always been exceptional. The cfr has been abyssmal. The study only highlighted how fast and easy eventual mutation was likely to occur in any event. The only saving grace is if some idiots do release this they are likely to also kill their own people.

                  Excerpt:

                  In principle the specific knowledge gained from biomedical research with influenza viruses might aid surveillance and suppression efforts. However, that decidedly optimistic view overlooks some inconvenient on-the-ground realities. Mother Nature may compose a completely novel killer virus at any time. A better use of limited resources may be ensuring that global surveillance efforts are adequate to detect emerging flu viruses as early as possible and providing the means to eradicate them swiftly.

                  The record of well-documented accidents involving a range of human and animal pathogens at biodefense and other facilities is not reassuring. For instance, the severe acute respiratory syndrome (SARS) virus has escaped containment several times.

                  Controlling the dissemination of information and restricting future work seems advisable. But, in a real sense for anyone hoping to deter bioterrorists, that cat is already out of the bag.

                  A quick review of recent publications will reveal the simple method used to select this new virus. Whether they possess the precise nucleotide sequences or not, knowing the general technique and, more important, now knowing with certainty that such a beast can be made, would-be terrorists can collect their own bird flu viruses in Asia and attempt to brew up a nightmare.

                  Despite the good intentions of the scientists working with engineered H5N1 and presumably other such viruses in the future, I object to potentially betting so many lives on the promise that these experiments can be undertaken in complete safety.

                      It seems clear to me, as a scientist, that when our discoveries have an impact in ways that threaten humanity existentially, we must sometimes delay the gratification that comes with publicizing our findings.

                        I find this whole research issue confusing; I'm not knowledgeable about how research projects are funded.

                        Surely when these were funded, the expectations were clear.. in that the goal was to do what was finally accomplished. I find it hard to believe that guidelines were not laid out as to what the researchers would do with the information if they were successful.

                            There is a charge of $30.00 to view this program which is a travesty in my opinion.

                            It should be very interesting, however. Here is a recent comment by Vincent Racaniello on this issue:

                            "Racaniello: Most virologists agree that the experiments should proceed and are not exceptionally dangerous. The exceptions are those who don't understand the science, and the bioterror community. These individuals have proliferated since 9/11 and the anthrax attacks. They are paid large sums of money to sit in offices and decree what scientists can or cannot do. They are not practicing scientists and they don't appear to understand the underlying science.

                            Entire academic departments and corporations have been funded by the U.S. government to ponder potential dangers and tell scientists what to do. We now have a bioterror-industrial complex that rivals the military-industrial complex that Dwight Eisenhower warned us about. It is a scam, and I hope one day the nature and extent of the wasted money will be revealed to the public."
