Drugmaker GlaxoSmithKline announced plans on Tuesday to donate 50 million doses of its H1N1 (swine flu) vaccine to the WHO for use in developing countries within the next few months, Reuters reports.
Despite reports that the numbers of new H1N1 (swine flu) are leveling off in some parts of the Northern Hemisphere, the virus continues to spread, the WHO said Friday, Reuters reports. “In an update on the H1N1 swine flu virus, the WHO said parts of the southern and southeastern United States, as well as Iceland and Ireland, seemed to have weakening levels of disease after an unusually early start of the winter flu season,” the news service writes.
Ahead of the anticipated CDC release of revised U.S. H1N1 (swine flu) death toll estimates, Reuters examines how the agency and WHO measure the impact of the virus, after both organizations “stopped trying to count actual cases months ago, once it became clear that H1N1 was a pandemic that would infect millions.”
“As researchers from both sides of the debate over two controversial H5N1 studies weighed in [Tuesday] on full publication versus a more cautionary approach, two U.S. journals” — the Journal of Infectious Diseases (JID) and its sister publication, Clinical Infectious Diseases — “said they are developing policies to address any future such instances,” CIDRAP News writes. “We are developing policies that address these issues on a case-by-case basis, so that freedom of scientific expression can be maintained without sacrificing individual safety or national security,” JID Editor Martin Hirsch wrote in an editorial, the news service notes, adding, “He also introduced three new JID perspective pieces that discuss the difficult issues” (Schnirring, 3/28).
The debate about two studies showing that, with few genetic mutations, H5N1 bird flu strains could become more easily transmissible among ferrets, a laboratory model for humans, “has become a debate about the role of science in society. Two questions should be addressed here: should this type of research be conducted at all; and if so, should all data generated by this research be published?” Ab Osterhaus, head of the Institute of Virology, at Erasmus Medical Centre in Rotterdam, writes in a Guardian opinion piece. A team from Erasmus conducted one of the two studies, he notes.
Keiji Fukuda, WHO assistant director-general for health security and environment, “is hoping bird flu studies currently in publishing limbo will be released by the time the agency hosts a second meeting on the controversy this summer,” the Canadian Press/Winnipeg Free Press reports. “A major break in the impasse would be needed for that to happen,” the Canadian Press writes, adding, “As things currently stand, revised versions of the two studies are due to be presented late this month to the U.S. biosecurity panel that earlier recommended against their full publication.”
Rep. Sensenbrenner Sends ‘Fact-Finding Letter’ To White House Science Adviser About Bird Flu Studies
“Representative Jim Sensenbrenner (R-Wis.), a former head of the House committees on science and the judiciary, and currently vice chair of the House Committee on Science, Space, and Technology, last week sent a ‘fact-finding letter’ to White House science adviser John Holdren, asking pointed questions about how the U.S. government has handled the controversy” surrounding two studies that showed how H5N1 bird flu virus could be manipulated to become transmissible among ferrets, a model for humans, “and questioning whether it should have funded the two flu studies,” ScienceInsider reports. “The [Obama] Administration’s response has appeared ad hoc, delayed, and inadequate,” Sensenbrenner writes, adding, “An ad hoc approach is inadequate to balance the priorities of public health and the free flow of academic ideas,” according to the article, which includes the full text of the letter.
Attendees of a recent WHO meeting that discussed the possible publication in the journals Nature and Science of two studies that modified H5N1 bird flu strains to show the virus could be more easily transmissible among humans decided publication of redacted versions would be ineffective and that “a system for distributing the full paper only to selected individuals would be impossible to set up on any relevant timescale,” a Nature editorial states. Participants also learned “not only does the mammalian transmissibility threat seem greater than previously thought, but also that current avian viruses have some of the mutations identified in the new work,” according to the editorial.
In an analysis (.pdf) published Thursday in the online edition of the journal Science, a team led by virologist Peter Palese of Mount Sinai School of Medicine in New York raises questions about the WHO’s estimated fatality rate from H5N1 bird flu, saying the rate of 59 percent is based on “an estimate of human bird flu cases that is simply too low,” Reuters reports. The WHO has recorded 586 cases of people infected by bird flu, and of those, 346 have died, the news agency notes (Begley, 2/23). Palese and colleagues say “it is not possible to determine an accurate fatality rate for H5N1 infections based on” available data, but “if one assumes a one to two percent infection rate in exposed populations, this would likely translate into millions of people who have been infected, worldwide” (Wang et al., 2/24). And in a paper published Friday in mBio, the journal of the American Society for Microbiology, Michael Osterholm of the University of Minnesota and a member of the U.S. National Science Advisory Board for Biosecurity (NSABB) and a colleague conclude that “[t]he available seroepidemiologic data for human H5N1 infection support the current WHO-reported case-fatality rates of 30% to 80%” (Osterholm/Kelley, 2/24).
NPR’s health blog “Shots” previews an upcoming WHO-convened meeting to discuss the recent news that two research teams have created H5N1 bird flu strains that are easily transmissible among ferrets, which are used as lab models for humans. Fears that terrorists possibly could use the information prompted the U.S. National Science Advisory Board for Biosecurity in December to request the scientists redact some information prior to publishing their study results and investigators in January to institute a 60-day moratorium on bird flu research, the blog notes.
