    Vogelgriep in Moskou
    Door PETER D’HAMECOURT

    MOSKOU - In de provincie Moskou zijn maatregelen getroffen om de vogelgriep binnen de perken te houden.

    Maatregelen worden genomen om de verspreiding van de volgelgriep rond Moskou tegen te gaan. Op vijf plaatsen zijn besmette kippen aangetroffen. Het Russische ministerie van Volksgezondheid heeft groot alarm geslagen nu vogelgriep is uitgebroken voor de poorten van Moskou. Tot gisteravond zijn zeker op vijf plaatsen in de provincie Moskou kippen aangetroffen die waren besmet met het dodelijke H5N1 virus. Er zijn nog geen mensen ziek geworden.

    De kippen waren allemaal door particulieren gekocht op de markten in Moskou. De handel in pluimvee is direct stilgelegd. Dat verbod blijft zeker een maand van kracht.

    De verkoop van kippenvlees op de markten van de hoofdstad is aan een extra controle onderworpen. Vandaag begint bovendien een grote inentingsactie op de boerderijen in de regio.

    Volgens de autoriteiten is er geen reden tot paniek, omdat het virus tot nu toe alleen is ontdekt bij particuliere kippenfokkers. Veel mensen in de provincie Moskou - die ongeveer zo groot is als Nederland - houden kippen om wat bij te verdienen met de verkoop van eieren en vlees op de lokale markten.

    Deze versnippering maakt de controle en het opsporen van besmette bronnen wel extra moeilijk. Er zijn verschillende telefoonlijnen geopend om kippenfokkers van informatie te voorzien of waar mensen vreemd gedrag van hun kippen kunnen melden.

    Voor de komende dagen is zeer strenge vorst voorspeld voor de Moskouse regio met temperaturen van 20 tot 25 graden onder nul. De vrieskou zorgt er voor dat het virus niet erg actief is en dat geeft de autoriteiten de tijd om een epidemie in de kiem te smoren.

    De vogelgriep heeft zich de afgelopen maanden sluipenderwijs in de richting van Moskou begeven. Afgelopen zomer dook het virus op in Siberië. Twee maanden geleden kwamen er meldingen uit de zuidelijke provincies van Rusland.

    EU says more work vital to deal with a flu pandemic
    Thu Feb 22, 2007 7:12PM GMT

    [-] Text [+] STOCKHOLM (Reuters) - The European Union is the best prepared area in the world to meet an influenza pandemic but still needs two or three years before it can cope fully, the EU's disease control agency said on Thursday.

    In a report, the European Center for Disease Prevention and Control (ECDC) urged EU nations to integrate preparations at national, local and international levels to expand influenza research and do more to combat seasonal outbreaks.

    "ECDC estimates that a further two to three years of sustained effort are needed by the EU and its member states to achieve the level of preparedness needed to respond well to a pandemic," it said.

    Zsuzsanna Jakab, director of the Stockholm-based agency, told a Web broadcast news conference member nations had "gone a long way" in preparation over the past 18 months to two years.

    "I already consider that at this stage the European Union is the best prepared region in the world if you compare it with other countries," she said.

    The ECDC report involved 25 EU states, plus Iceland and Norway. Another update is due later this year.

    Jakab said the EU must sustain this momentum for the next two to three years and take the steps set out in the report.

    "If this is done, then EU countries will be in a position to respond well to a pandemic," she said.

    A good response means primary care facilities and hospitals can treat influenza victims without reducing other activities, vaccines reach primary care systems within six months of an outbreak and food, power and fuel are still available at a local level.

    Health experts weigh bird-flu vaccine Tuesday that is even less effective than thought
    WASHINGTON: The federal government is weighing approval of a bird flu vaccine that is even less effective than previously thought.
    Sanofi Aventis SA, the maker, believes the benefits of the vaccine outweigh its risks. However, in a clinical trial, the two-shot series appears to provide protection to just 45 percent of adults who received the highest dose. An earlier, interim analysis of the same study suggested it prompted a protective immune response in 54 percent of patients, when measured 28 days after getting the second shot. The New England Journal of Medicine published those results in March 2006.
    The Food and Drug Administration released the more recent analysis ahead of a Tuesday meeting of outside experts asked to review the vaccine. The FDA said the 452-person study showed the vaccine against the deadly bird-flu strain called H5N1 is indeed safe, but it remained unclear whether it would be effective.
    The FDA is asking the panel whether Sanofi has provided enough data to back approval of its bird flu vaccine or if more are needed. The agency is not required to follow the advice of its advisory committees, but usually does. The vaccine is the first against the H5N1 influenza strain to seek FDA approval.

    Health officials also are studying the development of cell-based vaccines, which would be faster to produce in an outbreak of deadly flu than are current egg-based vaccines. The FDA suggested the Sanofi vaccine, if approved, could be used on an interim basis until others are developed.

    Second mock-up pandemic influenza vaccine receives positive opinion

    The Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion recommending the granting of a marketing authorisation for Focetria, from Novartis Vaccines and Diagnostics S.r.l. Focetria is a mock-up pandemic influenza vaccine, intended for the prevention of influenza during an officially declared pandemic situation, once the pandemic viral strain has been included. It is the second mock-up pandemic influenza vaccine to receive a positive opinion from the Committee. EMEA review began on 31 January 2006 with an active review time of 162 days.
    Mock-up pandemic influenza vaccines are approved only for use in a declared pandemic influenza situation. The objective is to have a marketing authorisation in place that can be changed quickly in the event of a pandemic to include the virus strain responsible, once it has been identified.

    FDA: Sanofi H5N1 Vaccine Safe, Not Clear How Effective >SNYLast update: 2/26/2007 11:21:06 AM

    By Jennifer Corbett Dooren
    Of DOW JONES NEWSWIRES
    WASHINGTON (Dow Jones)--The U.S. Food and Drug Administration said Monday an H5N1 vaccine by a unit of Sanofi Aventis (SNY) appeared to be safe, but that it's not clear how effective the vaccine would be at protecting people against avian influenza. The FDA posted its views of the vaccine a day ahead of a panel meeting of outside medical experts that's expected to weigh in on whether it believes the vaccine is safe and effective. Currently there are no vaccines approved for human use in the U.S. for avian influenza virus such as H5N1. Sanofi's vaccine is designed to protect humans against a particular H5N1 influenza strain that first started spreading among birds, and it's not clear if the vaccine would offer protection in the event the virus mutates. Since 2003, the H5N1 strain has infected 274 people in 11 countries and resulted in 167 deaths, mostly in Asia and Africa. Most of the human cases have been caused by direct contact with infected poultry, but health experts are concerned that if the virus mutates it might be able to spread easily among humans and spark the next pandemic. The FDA said clinical studies of Sanofi's vaccine showed "no significant safety signals that would preclude administration of this vaccine to additional persons." The FDa said the highest doses tested, two 90-microgram doses given one month apart, elicited a better immune response than lower doses that were tested. Based on previous research, the immune responses shown from the higher doses of the Sanofi H5N1 vaccine suggests it would offer "50% protection against influenza illnesses" or work in about half of the people given the vaccine.

    FDA advisers OK Sanofi bird flu vaccine
    Sanofi's experimental bird flu vaccine gets nod from FDA advisory panel for safety, effectiveness.
    By Aaron Smith, CNNMoney.com staff writer
    February 27 2007: 6:18 PM EST

    NEW YORK (CNNMoney.com) -- A panel of FDA advisers voted to recommend approval of an experimental bird flu vaccine from the French drugmaker Sanofi-Aventis determining that it was safe and effective for the U.S. population, the company and the FDA said Tuesday.

    If approved, Sanofi's (down $0.87 to $42.84, Charts) vaccine would be the first in the United States for the prevention of the bird flu, called H5N1. The Food and Drug Administration must still decide whether to OK the vaccine for use in the United States. The FDA usually follows the advice of its advisers.

    "This is an important first step to preparing this nation for the pandemic," said Phil Hosbach, vice president of policy and government relations for Sanofi. "That means we have a chance at saving lives and halting the spread of the virus with this vaccine. The alternative is having nothing."

    Some experts fear that the bird-flu virus will mutate into a strain that can be easily transmitted from human to human, sparking a mass pandemic.

    This virus has posed the greatest threat to birds, infecting flocks in Asia and Europe, even spurring the government-mandated killing of millions of birds from poultry farms.

    The fatal virus can spread to humans who are in close contact with infected birds. So far, 270 people in 10 countries have been infected and 164 of them have died, according to the FDA.

    British drugmaker GlaxoSmithKline (down $1.21 to $55.70, Charts) is also developing a bird flu vaccine, which it submitted to European regulators on Jan. 29.

    Swiss drug giant Roche produces the only FDA-approved treatment for bird flu: the anti-viral drug Tamiflu, which is not a vaccine. BioCryst (down $0.53 to $10.23, Charts) is developing an anti-viral, peramivir, that might someday compete with Tamiflu. Novartis (down $1.80 to $55.32, Charts), MedImmune (down $0.59 to $32.45, Charts) and Novavax (down $0.32 to $3.43, Charts) are also working on bird flu-related products.

    Are Some People Immune To Avian Flu?
    Science Daily — New results from Richard Webby at St. Jude Children's Research Hospital and colleagues published in the international open-access medical journal PLoS Medicine suggest that the answer might be yes.

    Neuraminidase ribbon diagram. (Image courtesy of PLoS Medicine)The H5N1 avian flu virus is quite different from the seasonal H1N1 and H3N2 flu viruses most humans have been exposed to, which is why many scientists believe that H5N1 could start a new pandemic. (The H and N refer to two virus components, the proteins hemagglutinin and neuraminidase, each of which exists in several varieties identified by a number following the letter.)

    Webby and colleagues wondered whether immunity to the human type 1 neuraminidase (huN1) in H1N1 influenza virus strains (and vaccines made to protect against them) could provide protection against avian H5N1 influenza virus, which contains the closely related avian type 1 neuraminidase (avN1). In the new study, they investigated this possibility in mice and in a small group of humans.

    The researchers immunized mice with DNA that caused their cells to make the neuraminidase from an H1N1 virus found in human outbreaks. They then examined the immune response of the mice to this huN1 and to avN1 from an avian H5N1 virus isolated from a human patient (A/Vietnam/1203/04). Most of the mice responded to the DNA vaccine by making antibodies that recognized huN1; a few also made antibodies against avN1. (Antibodies are proteins circulating in the body that recognize and stick to some specific part of a foreign agent such as a virus.) All the vaccinated mice survived infection with a man-made flu virus containing huN1, and half also survived infection with low doses of A/Vietnam/1203/04 or of a man-made virus containing avN1.

    The researchers then tested blood samples from 38 human volunteers for their ability to inactivate neuraminidase from an H1N1 virus and two H5N1 viruses. Most of the samples were active against the protein from the H1N1 virus; and 8 or 9 also inhibited the protein from both H5N1 viruses.

    The results indicate that a vaccine containing huN1 makes mice produce antibodies that partly protect them against avian H5N1 infection. In addition, the human data suggest that a proportion of people have low titer antibodies against H5N1 influenza because of prior exposure to H1N1 viruses or routine influenza vaccination.

    As Laura Gillim-Ross and Kanta Subbarao (US National Institute of Allergy and Infectious Diseases) write in an accompanying Perspective article, these results provide a tantalizing suggestion but fall short of demonstrating that there is actual protection in humans against avian flu. Further work is needed to investigate this important question, and Gillim-Ross and Subbarao discuss the challenges and opportunities for such research.

    Press Release: Influenza Prediction Market to Help Strengthen Early Warning System for U.S. Bird Flu Outbreak

    March 2, 2007

    Influenza Prediction Market to Help Strengthen Early Warning System for U.S. Bird Flu Outbreak

    New Robert Wood Johnson Foundation-funded prediction tool will give public health officials better forecasting and response capabilities

    To prepare for a bird flu pandemic, the University of Iowa today unveiled a new tool to help public health officials better predict when the disease will strike and plan ways to stem its effects. Through a unique collaboration among the University's Colleges of Business and Medicine, the Iowa Health Prediction Market is launching the "Avian Flu Market (AFM)," an information trading and aggregation system to help public health officials around the world collect and analyze information to forecast the timing and extent of a human-to-human bird flu outbreak. The project is supported by a $245,685 grant from the Robert Wood Johnson Foundation (RWJF).

    "Many health care workers are the first to know about influenza activity in their communities and that information can help predict the course of an infectious disease. This forecasting tool taps into that disperse knowledge to provide important new information about the development and spread of avian flu, and better ready ourselves to protect public health both here and abroad," says Forrest Nelson, Ph.D., economics professor, Tippie College of Business and principal investigator on the project.

    The avian, or bird, flu is caused by the H5N1 strain of influenza virus. The H5N1 virus has killed at least 154 people out of 258 human cases. To date, the virus has only passed from birds to humans. Some experts fear that if the virus mutates to spread between humans, it could spark a pandemic similar to the Spanish influenza pandemic of 1918, which killed tens of millions of people around the world, and half-a-million in the United States alone.

    The AFM is a spin-off of the Iowa Electronic Market (IEM), which, since beginning in 1988, has achieved an impressive prediction record that is superior to alternative mechanisms such as opinion polls. Such markets have been significantly more accurate than traditional tools in predicting outcomes ranging from political election results to movie box office receipts; they are also used by the private sector to forecast trends such as which printers will sell or which drugs have the best chance of advancing through clinical trials. The University of Iowa Health Prediction Market is the first to use them as predictive tools in the medical and public health arenas.

    "Farmers have used futures markets for decades to make decisions about what crops to plant. We're just borrowing that concept to help people in public health and health care make decisions about the future," says Phil Polgreen, M.D., assistant professor of medicine in the UI Carver College of Medicine, director of the Infectious Disease Society of America's Emerging Infections Network and AFM co-principle investigator.

    "We're already doing this with our seasonal influenza market," says Polgreen. First opened in 2004, the Flu Activity Market is designed to predict when flu activity will start, peak and end within a state. Since its inception, the market has provided a two-to-four week advance warning of when the flu season would hit Iowans, and a similar state market launched this season in North Carolina. These efforts are supported by a separate RWJF grant.

    "The early success of the seasonal flu prediction market showed that innovative tools from other fields may fuel important breakthroughs when applied to health and health care," says Robert G. Hughes, Ph.D., RWJF chief learning officer. "The threat of an avian flu pandemic remains urgent, and the Robert Wood Johnson Foundation is pleased to support this effort to expand the range of forecasting and surveillance tools available to public health and safety leaders."

    The AFM will target doctors, nurses, researchers, epidemiologists, public health and other medical workers who have some knowledge of the flu virus' development and will trade in the market based upon their beliefs about its future spread. Participants will be recruited through the Program for Monitoring Emerging Diseases (ProMED), an online global reporting system run by the International Society for Infectious Diseases that rapidly distributes information about outbreaks. Lawrence Madoff, M.D., associate professor of medicine, Harvard Medical School and ProMED editor, is a co-principal investigator of the AFM project. He notes that "the prediction markets project will enable ProMED participants, an unusually well-informed group with access to the most complete and current information, to help quantify the likelihood of various outcomes. This furthers our goals of early detection of outbreaks and enhancing public health preparedness."

    Participants will trade in the AFM to predict the likelihood of different avian influenza watershed events. For example, one market aims to predict whether Phase Four of the WHO-defined Pandemic Alert Period is declared by July 1 of this year, and a second attempts to pinpoint when bird flu will spread to the Americas. The market addresses other questions including the number of potential human infections and the spread of H5N1 among the avian and animal populations across the world. AFM participants will trade using virtual currency, and any profits will be paid in the form of educational grants to be applied toward things like journal subscriptions, conference fees and other supplies. Individual profits or losses will differ depending upon the accuracy of the trader's predictions, though no participant stands to lose money; at worst, one can only reach a zero balance in her trading account.

    Project leaders believe that by recruiting health experts from around the world to participate in the AFM, more effective prevention measures can be put into place more quickly, thus limiting the virus' spread and potentially deadly consequences.

    According to Nelson, "surveillance efforts of state, federal and international health agencies focus almost exclusively on the spread of influenza today and yesterday, with no systematic attempts to quantify predictions of what might happen tomorrow. These Avian and Seasonal Influenza Markets thus fill a void in the arsenal of surveillance tools available to professionals and the public."

    "This has the potential to be enormously helpful for planners who have to coordinate resources, such as vaccine supplies, and contact those most vulnerable to infection," says Polgreen. "The real goal is to try to change the way people think about public health information. We are trying to come up with a new way to plan for the future, one that is easy to use, efficient, and inexpensive."

    The Robert Wood Johnson Foundation is the nation's largest philanthropy devoted exclusively to improving health and health care for all Americans. Funding was provided through the Foundation's Pioneer Portfolio, which seeks to identify innovations that can lead to fundamental breakthroughs in health and health care.

    RTRS-Japan waarschuwt voor Tamiflu wegens zelfmoorden
    TOKIO (ANP) - Japan heeft de importeur van Tamiflu
    gewaarschuwd dat het griepmedicijn niet moet worden
    voorgeschreven aan tieners. Dit moet de producent Roche in de
    bijsluiter opnemen.

    Het ministerie van gezondheid grijpt in naar aanleiding van
    een lopend onderzoek naar minstens zestien zelfmoorden sinds
    2001 onder Japanse jongeren, die het medicijn Tamiflu hadden
    geslikt. Een verband is echter nog niet aangetoond.

    Eind vorig jaar waarschuwden Amerikaanse autoriteiten voor
    psychiatrische afwijkingen door gebruik van Tamiflu. Een
    waarschuwing op de bijsluiter is daar ook al verplicht. De
    Europese geneesmiddelenautoriteit EMEA kondigde vorig jaar
    verscherpt toezicht aan op de mogelijke bijwerkingen van de
    virusremmer.

    De beslissing kan een belangrijke impact hebben op de
    verkoop van Tamiflu. Japan koopt namelijk 60 procent van alle
    Tamiflu medicijnen. Het Aziatische land is een van de weinige
    landen die de virusremmer ook voor seizoensgebonden griep
    voorschrijft. Tamiflu wordt bovendien gezien als het beste
    medicijn tegen de vogelgriep. Dit virus heeft wereldwijd 160
    levens geëist. De meeste slachtoffers vielen in Azië.

    RTRS-Intervet krijgt tweede EU-registratie vogelgriepvaccin
    BOXMEER (ANP) - Een tweede vaccin dat Intervet heeft
    ontwikkeld tegen vogelgriep, is vrijdag officieel geregistreerd
    in de Europese Unie. Daardoor beschikt Europa nu over een
    officieel griepvaccin dat vogels en eenden beschermt tegen het
    actuele H7N1-virus.

    Dat heeft Intervet, onderdeel van het farmaciebedrijf
    Organon uit Oss, vrijdag gemeld. Intervet is 's werelds grootste
    producent van vaccins voor dieren.

    Wereldwijd zijn er de laatste zeven jaar verschillende
    uitbraken geweest van H7-virussen geweest. In 2003 moesten 30
    miljoen vogels worden geruimd bij een uitbraak. Tot nu toe ging
    de meeste aandacht uit naar de virussen met de H5-stam, die net
    als de H7-virussen kan overgaan op mensen. Intervet kreeg vorig
    jaar al een EU-registratie voor het H5N2-virus.

    Organon behoort nu nog tot Akzo Nobel. Het Amerikaanse
    farmacieconcern Schering-Plough heeft echter een akkoord bereikt
    met het concern over een overname van het onderdeel, inclusief
    Intervet. Daarmee is 11 miljard euro gemoeid.

    Aus dem Blut von überlebenden Vogelgrippepatienten haben Wissenschaftler Antikörper gegen H5N1 isoliert. Sie könnten Erkrankten damit möglicherweise erstmals wirksam helfen. Im Labor haben die Imunstoffe das Virus bereits außer Gefecht gesetzt.

    Weltweit suchen Forscher nach Heilmethoden gegen das H5N1-VirusH5N1 ist ein Virus, das sich überwiegend in Vögeln vermehrt. Bei direktem Kontakt mit dem Federvieh können sich aber auch Menschen und andere Säugetiere anstecken. Die Weltgesundheitsorganisation WHO berichtet, dass bis Mitte Mai 2007 insgesamt 306 Fälle von Vogelgrippe unter Menschen bekannt wurden. 185 der Patienten starben an dem Virus.

    Ein internationales Team von Medizinern konnte nun zeigen, dass Antikörper, die sie aus dem Blut zweier überlebender vietnamesischer Patienten gewonnen hatten, im Laborversuch Mäuse vor einer Infektion mit dem Virus schützten. 20 bereits erkrankte Nager erholten sich durch die Gabe der Immunstoffe während die 20 infizierten Tiere einer Kontrollgruppe ......

    Mogelijk menselijke antistoffen H5N1
    Er zijn mogelijk menselijke antistoffen tegen de voor mensen dodelijke H5N1-variant van vogelgriep. Dat zeggen wetenschappers in het medische blad PLoS Medicine.

    Muizen
    De onderzoekers gebruikten antistoffen van Vietnamezen die een besmetting met het virus hadden overleefd. Muizen die de antistoffen toegediend hadden gekregen, werden expres besmet met H5N1. Ze werden niet ziek. Muizen die de vogelgriep al hadden en de antistoffen kregen, leefden langer dan dieren die de antistoffen niet kregen.

    Vaccin
    Het verschil tussen een vaccin en antistoffen is dat een vaccin weliswaar langere tijd bescherming biedt tegen een ziekte, maar pas na enkele weken of zelfs maanden gaat werken. Antistoffen werken direct, maar bieden waarschijnlijk slechts enkele maanden bescherming.

    zijn er in het voorjaar veertien wilde
    zwanen gevonden die aan deze vorm van
    vogelgriep waren doodgegaan.

    Op de getroffen boerderij,150 kilometer
    ten oosten van Praag,zijn 1800 van de
    6000 kalkoenen aan het virus bezweken.
    De overige dieren worden afgemaakt.De
    werknemers op de boerderij krijgen uit
    voorzorg een anti-virusmedicijn.

    In de Duitse deelstaat Beieren is vogelgriep geconstateerd.
    Bij vijf zwanen en een eend is het voor de mens gevaarlijke H5N1 virus geconstateerd.

    ***************************************
    Vogelgriep in Duitsland is H5N1

    ***************************************
    ` Van de veertien dode watervogels die
    zijn gevonden in het zuiden van
    Duitsland blijken er zes te zijn besmet
    met de voor mensen gevaarlijke variant
    van vogelgriep,H5N1.Vermoed wordt dat
    de andere het ook hebben.

    De autoriteiten hebben een gebied in
    een straal van vier kilometer rond de
    vindplaats van de dode watervogels tot
    verboden gebied verklaard.Huisdieren
    moeten ook binnen blijven.

    De gezondheidsdienst in Neurenberg zegt
    dat de kans dat mensen met het virus
    worden besmet erg klein is,maar voor de
    zekerheid krijgen mensen het advies
    geen watervogels aan te raken.

    Vogelgriep duikt op in Duitsland
    In Neurenberg in het zuiden van Duitsland is de dodelijke variant van de vogelgriep opgedoken. Dat meldt de Duitse zender ZDF. Het gaat om de gevaarlijke variant H5N1 , zo blijkt uit onderzoek.

    Het gaat om de ook voor mensen gevaarlijke variant H5N1, maakte de regionale milieudienst zondag bekend. Het zijn de eerste bevestigde gevallen bij wilde dieren in de Europese Unie dit jaar, meldde de Europese Commissie in Brussel.

    Pluimveehouders in de omgeving moeten stallen dichthouden en bezoek weren. Honden en katten mogen niet langer vrij rondlopen in de directe omgeving van waar de dode vogels werden gevonden, aldus de Duitse televisie. De maatregelen gelden vooralsnog drie weken.

    Dossier: Vogelgriep
    In Duitsland was in augustus vorig jaar voor het laatst vogelgriep vastgesteld na een epidemie in zes van de zestien deelstaten. Het laatste geval betrof een zwaan in de dierentuin van Dresden. In totaal raakten vorig jaar in de Europese Unie zevenhonderd wilde vogels met H5N1 geïnfecteerd.

    Het ministerie van Landbouw, Natuurbeheer en Voedselkwaliteit heeft laten weten dat Nederland geen maatregelen neemt in verband met de vogelgriep in Duitsland. ,,Het gaat hier niet om dieren in een commercieel bedrijf, maar om wilde zwanen. Wordt in een bedrijf vogelgriep ontdekt, zoals vorige week in Tsjechië, dan worden transportauto's waarmee pluimvee of eieren van en naar die regio zijn vervoerd extra gereinigd en schoongemaakt. Dat is nu niet het geval.''
