NIH responds to criticism over handling of flu papers

The US National Institutes of Health (NIH) today released a response to a sharply worded internal criticism about the handling of two controversial H5N1 avian influenza papers, one of which was published in Nature yesterday.

The criticism came from Michael Osterholm, a public-health researcher and member of the National Science Advisory Board for Biosecurity (NSABB), which had been asked to advise the government on the potential biosecurity risks of publishing the papers in full. After an initial unanimous recommendation to redact the papers, the 22 voting members of NSABB were called back to the NIH campus to re-evaluate the decision in light of additional information and revisions to the papers. This time it voted in favour of publication, but six members of the NSABB, including Osterholm, dissented on the publication of one of the manuscripts.

Osterholm’s letter, which was leaked to Science and Nature, called the proceedings of this meeting, held 29–30 March, biased and incomplete, presenting an argument with the express purpose of getting the papers published.

In a six-page response — released today, but dated 25 April — Amy Patterson, an NIH official who manages the NSABB, responded to Osterholm’s critiques point by point. She writes that the views and perspectives that Osterholm claims were lacking at the meeting were in fact presented, by Osterholm himself. She says that he did not provide recommendations for experts to speak at the meeting. (In his letter, Osterholm said, “I personally tried to have their voices represented at the meeting. They were not invited.”) And she notes that although she respects his opinions and perspectives, “I do believe that some of them were based in part on a misunderstanding of the facts.”

Interestingly, Patterson notes that the US government is now looking into ways to allow “controlled access to sensitive scientific information for those with a legitimate need to know, in cases where certain details are redacted from a manuscript.” This is a mechanism that many members in the NSABB have been calling for, but one that obviously wasn’t ready for the H5N1 papers. Many in the scientific community worry that this redaction process is tantamount to censorship and that it has delicate political implications internationally. Without involvement from the rest of the world, it could seem that the United States or a handful of developed countries are attempting to unilaterally control the release of potentially dangerous information.

Mutations behind flu spread revealed

Two scientists recently hit the headlines when they created mutant strains of H5N1 influenza, which can spread between mammals (see ‘Fears grow over lab-bred flu‘). But although Ron Fouchier of Erasmus Medical Center in Rotterdam, the Netherlands, spoke publicly to explain and defend the work, Yoshihiro Kawaoka, of the School of Veterinary Medicine at the University of Wisconsin–Madison, has been far quieter, deliberately saying nothing to the press.

That has now changed. At a Royal Society meeting in London about H5N1 research yesterday, the thus-far silent scientist spoke openly about his results after the National Science Advisory Board for Biosecurity (NSABB), an independent advisory group to the US government, unanimously voted last week that Kawaoka’s paper should be published in full. Nature intends to “proceed with publication as soon as possible”.

His experiments began when he tweaked the H5N1 virus to reproduce in a ferret’s airways. He introduced random alterations into its haemagglutinin (HA) protein, which it uses to stick to host cells. From the resulting library of mutants, he isolated viruses with two mutations in HA — N224K and Q226L — that could stick to receptors in human tracheal cells. That is something H5N1 viruses cannot usually do. Continue reading
