A very public controversy has arisen from the creation of two influenza A viruses based all or in part on highly pathogenic avian influenza (HPAI) H5N1 strains. These viruses were genetically modified, specifically and intentionally, to enhance their ability to transmit by air between ferrets, a commonly used animal model for influenza virus transmission studies. One virus, from the Erasmus Medical Center in the Netherlands, was mutated to include 3 amino acid polymorphisms already known to enhance the transmissibility of avian influenza virus strains among mammals. When that virus failed to transmit from ferret to ferret by air, it was then serially passaged through more ferrets until it acquired 2 further mutations, one or both of which conferred airborne transmissibility among ferrets. The resulting virus was initially described as similarly pathogenic as related H5N1 viruses, which cause severe disease in this species, and as efficiently transmissible as seasonal influenza viruses [1, 2]. Subsequent data from the Erasmus group, however, suggest that the airborne virus is actually less transmissible and less virulent than original reports seemed to indicate [3].The other virus, engineered at the University of Wisconsin–Madison, took the hemagglutinin (HA) receptor-binding proteins from several H5N1 viruses and expressed them with the remaining viral genes from a 2009 pandemic H1N1 (H1N1pdm09) influenza strain. It appears that at least one of these H5N1-H1N1 reassortant viruses was able to transmit among ferrets via airborne respiratory particles; however, like its parental H1N1pdm09 virus, it did not kill infected ferrets [4]. Both groups of researchers submitted their findings to respected scientific journals, the Erasmus group to Science and the Wisconsin group to Nature, and both manuscripts were peer-reviewed and accepted for publication. However, the National Science Advisory Board for Biosecurity (NSABB), which advises the US government on dual-use research (defined as “biological research with legitimate scientific purpose that may be misused to pose a biologic threat to public health and/or national security”[5]) concluded that the “significant potential for harm in fully publishing these results… exceeded the benefits of publication” and, thus, recommended that “communication of the results in the two manuscripts… should be greatly limited in terms of the experimental details and results”[6]. As of this writing, the journals and the authors appear prepared to accept the NSABB’s
