“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.
The National Science Advisory Board for Biosecurity (NSABB) is scheduled this week to hold “a closed-door meeting to once again look at unpublished manuscripts describing” two studies that showed how H5N1 bird flu virus could be manipulated to become transmissible among ferrets, a model for humans, NPR’s health blog “Shots” reports, noting that the meeting “will include a classified briefing from the intelligence community.” The article examines the “dual use” nature of the studies, meaning “legitimate scientific work that’s intended to advance science or medicine, but that also might be misused with the intent to do harm.” Though the “concept of dual use got a lot of attention even before this bird flu controversy,” scientists, institutions and funding agencies do not always have policies in place to review the potential consequences of research, the blog notes (Greenfieldboyce, 3/26).
“The U.S. government [on Thursday] released a new policy [.pdf] that will require federal agencies to systematically review the potential risks associated with federally funded studies involving 15 ‘high consequence’ pathogens and toxins, including the H5N1 avian influenza virus,” Science Insider reports. “The reviews are designed to reduce the risks associated with ‘dual use research of concern’ (DURC) that could be used for good or evil,” the news service writes (Malakoff, 3/29).
U.S. Panel May Re-Evaluate Bird Flu Research After Scientists Present New Data About Risks To Humans
Speaking at the American Society for Microbiology’s (ASM) Biodefense and Emerging Diseases Research meeting in Washington, D.C. on Wednesday, Ron Fouchier, the leader of the team at Erasmus Medical Center in the Netherlands that genetically altered the bird flu virus, making it transmissible between ferrets and “touching off public fears of a pandemic, said … that the virus he created was neither as contagious nor as dangerous as people had been led to believe …, prompt[ing] the United States government to ask that the experiments be re-evaluated by a government advisory panel that recommended in December that certain details of the work be kept secret and not published,” the New York Times reports (Grady, 2/29).
Number Of Fatalities From 2009 Swine Flu Pandemic Might Have Been 15 Times Higher Than Reported Deaths, Study Says
In a study published on Monday in the Lancet Infectious Diseases, researchers from the Centers for Disease Control and Prevention (CDC) said the 2009 H1N1 swine flu pandemic likely killed about 284,500 people worldwide between August 2009 and August 2010, a number 15 times higher than the 18,500 deaths reported to the WHO, Bloomberg News reports. “More than half the deaths may have been in southeast Asia and Africa, compared with 12 percent of officially reported fatalities, the authors wrote,” the news agency states (Bennett, 6/25). The reported cases “were only the deaths confirmed by lab testing, which the WHO itself warned was a gross underestimate because the deaths of people without access to the health system go uncounted, and because the virus is not always detectable after a victim dies,” Reuters writes (Begley, 6/25).
The New York Times examines several studies published in the journals Nature and Science looking at how the H5N1 bird flu virus could mutate to become more virulent among humans and outlines the history of controversy surrounding the studies. “While scientists have offered two possible ways in which H5N1 might become a human flu, they’re almost certainly not the only two,” the newspaper writes, adding, “There is no checklist of mutations that any bird flu must acquire to start infecting humans.” According to the newspaper, “Anthony S. Fauci, director of the National Institute of Allergy and Infectious Diseases, hopes scientists will be able to amass a longer list of potential mutations, and even find a common denominator in how they alter H5N1,” which might make it “possible to monitor emerging strains for signs that they are about to cross over into humans” (Zimmer, 6/25).
U.S. Clinical Trials Show Single Dose Of H1N1 Vaccine Protects Pregnant Women, Children Under 10 Need Two Doses
U.S. government data released on Monday confirmed that a single dose of the vaccine protects pregnant women from the virus, while children under the age of 10 years need two doses of the vaccine, the Washington Post reports. The findings came the same day that a team of experts tasked with monitoring the national H1N1 vaccine campaign for any adverse side effects met for the first time.
