Back in December, a US government panel took the highly controversial position of calling for the censoring of scientific work aimed at an understanding of how the H5N1 “bird flu” virus can change to become directly transmissible between humans. The virus is deadly to humans but can not be spread from one person to another. Instead, close contact with infected birds is required for humans to be infected. The work which the National Science Advisory Board for Biosecurity (which, as described in the Washington Post article linked above, “was created after the anthrax bioterrorism attacks of 2001”) wanted to censor involved experiments aimed at understanding precisely what changes in the virus would be required for it to retain its lethality while also becoming directly transmissible between humans through processes such as the sneeze caught in the disgusting high-speed photo from CDC seen here.
After a very long delay, the first of the two delayed papers was published in Nature last month. Now, the second paper has been published in Science, where the journal has taken the unusual step of dedicating an entire issue to the single topic of the H5N1 virus and has removed the subscription requirements for access.
Scientists seeking to fight future pandemics have created a variety of “bird flu” potentially so dangerous that a federal advisory panel has for the first time asked two science journals to hold back on publishing details of research.
In the experiments, university-based scientists in the Netherlands and Wisconsin created a version of the so-called H5N1 influenza virus that is highly lethal and easily transmissible between ferrets, the lab animals that most closely mirror human beings in flu research.
The problem is that once the details of the experiments and their results were released, the viruses produced by both of the independent laboratories by different processes lost their lethality as they became transmissible between ferrets, which were used as a model of transmission among humans. It turns out then, that the feared “supervirus” which the NSABB was assuming had been created did not even exist, so the “risk” from publishing details of how one could create it was totally unfounded.
