Thiomersal (thimerosal) is added as a preservative. In 2013, the New Scientist reported that "part of a surface protein on the pandemic virus looks very similar to part of a brain protein that helps keep people awake". [31][32], In 2014, a Finnish group published results that showed Pandemrix contained a higher amounts of structurally altered viral nucleoproteins than Arepanrix, a similar vaccine not associated with narcolepsy. Anticipating a severe influenza pandemic, governments around the world had made various logistical and legal arrangements to shorten the time between recognition of a pandemic virus and the production of a vaccine and administration of that vaccine in the population. Being manufactured in chicken eggs, it contains trace amounts of egg proteins. "[10], The vaccine is supplied in separate vials, one containing the adjuvant, and the other the inactivated virus,[11] which require mixing before intramuscular injection. influenza vaccine (H1N1)v (split virion, inactivated, adjuvanted) A/California/7/2009 (H1N1)v like strain (x-179a). Pandemrix should only be used if the recommended annual seasonal trivalent / quadrivalent influenza vaccines are not available and if immunisation against (H1N1)v is considered necessary (see sections 4.4 and 4.8). [9], While other 2009 H1N1 vaccines have been developed, the use of a proprietary immunologic adjuvant is claimed to boost the potency of the body's immune response, meaning that only a quarter of the inactivated virus is needed. [4], In August 2010, The Swedish Medical Products Agency (MPA) and The Finnish National Institute for Health and Welfare (THL) launched investigations regarding the development of narcolepsy as a possible side effect to Pandemrix flu vaccination in children,[5] and found a 6.6-fold increased risk among children and youths, resulting in 3.6 additional cases of narcolepsy per 100,000 vaccinated subjects. A similar story was playing out in the UK, with prominent organisations, including the Department of Health, British Medical Association, and Royal Colleges of General Practitioners, working hard to convince a reluctant NHS workforce to get vaccinated.2 “We fully support the swine flu vaccination programme … The vaccine has been thoroughly tested,” they declared in a joint statement.3, Except, it hadn’t. European Medicines AgencyDomenico Scarlattilaan 61083 HS AmsterdamThe Netherlands. [2], The vaccine was one of the H1N1 vaccines approved for use by the European Commission in September 2009, upon the recommendations of the European Medicines Agency (EMEA). The vaccine was developed by GlaxoSmithKline (GSK) [1] and patented in September 2006. A study by the Stanford University School of Medicine examined the incidence of narcolepsy in relation to upper airway infection and a H1N1 vaccine (not Pandemrix) in Chinese patients. Peter Doshi asks what this means for the future of transparency during public health emergencies. [21], On 27 August 2010, the European Medicines Agency announced that the agency's Committee for Medicinal Products for Human Use would be launching a review of Pandemrix in light of the "limited number of cases"[22] reported in Finland and Sweden, so as to "determine whether there is evidence for a causal association". Additionally, MPA says it is aware of individual case reports from France, Norway and Germany. [23], In August 2010 the Swedish MPA issued a statement which included the following: "An investigation is ongoing, but any relationship between the vaccination and the reported symptoms can not be concluded." Pandemrix should be used in accordance with Official Guidance. Le risque de survenue de narcolepsie après une vaccination par PANDEMRIX reste très faible, estimé à environ 3 à 7 cas additionnels de narcolepsie pour 100 000 sujets vaccinés chez les enfants et à environ 1 à 2 cas additionnels pour 100 000 sujets vaccinés chez les jeunes adultes. Prophylaxis of influenza caused by A (H1N1)v 2009 virus. Additional important non-medicinal ingredients are formaldehyde, sodium deoxycholate, and sucrose.

Another element, adopted by countries such as Canada, the US, UK, France, and Germany, was to provide vaccine manufacturers indemnity from liability for wrongdoing, thereby reducing the risk of a lawsuit stemming from vaccine related injury.45. These relate to vaccination against H5N1 (Bird Flu) and not H1N1 (Swine Flu).

Both organizations, in consultation with external experts, have assessed the possible relationship between the vaccination and the reported reactions. As well as the active antigen derived from A/California/7/2009 (H1N1), the vaccine contains an immunologic adjuvant AS03 which consists of DL-α-tocopherol (vitamin E), squalene and polysorbate 80. La commission européenne a accordé l'autorisation de mise sur le marché pour ces deux vaccins le 29 septembre 2009. "[28] Eight years after the pandemic influenza outbreak, a lawsuit alleging that GlaxoSmithKline’s Pandemrix vaccine caused narcolepsy has unearthed internal reports suggesting problems with the vaccine’s safety. Pandemrix is an influenza vaccine for influenza pandemics, such as the 2009 flu pandemic. [24], In February 2011, THL concluded that there is a clear connection between the Pandemrix vaccination campaign of 2009 and 2010 and the narcolepsy epidemic in Finland. A total of 152 cases of narcolepsy have been found in Finland during 2009–2010, and ninety percent of them had received the Pandemrix vaccination. MPA and THL have been in contact with other EU member states to enquire whether there have been any similar reports in other countries. In October 2009, the US National Institutes of Health infectious diseases chief, Anthony Fauci, appeared on YouTube to reassure Americans about the safety of the “swine flu” vaccine. Adverse events: GSK pandemic influenza vaccines, Eight years after the pandemic influenza outbreak, a lawsuit alleging that GlaxoSmithKline’s Pandemrix vaccine caused narcolepsy has unearthed internal reports suggesting problems with the vaccine’s safety. You are therefore advised to be selective about which sections or pages you wish to print. Four months earlier, the World Health Organization had declared H1N1 influenza a pandemic, and by October 2009 the new vaccines were being rolled out across the world. Après évaluation de ces données, l’EMA a émis le 25 septembre 2009 un avis positif pour deux vaccins, Pandemrix (Laboratoire GlaxoSmithKline Biologicals) et Focetria (Laboratoire Novartis Vaccines and Diagnostics). Authorities believe that the number of cases may still increase.[25][26][27]. Pandemrix should be used in accordance with Official Guidance. La vaccination contre la grippe A (H1N1) de 2009-2010 est inédite à l'échelle internationale à la fois par la rapidité avec laquelle les vaccins ont été développés, par les campagnes de vaccinations organisées, ainsi que par l'ampleur des polémiques déclenchées. [9], Professor David Salisbury, Head of Immunisation at the UK Department of Health said the vaccines with adjuvants offer good protection even if the virus changes over time; "One of the advantages with adjuvanted vaccines is their ability to protect against drifted (mutated) strains.

The United Kingdom (UK) withdrew from the European Union (EU) on 31 January 2020 and is no longer an EU Member State. [29] However, the original scientific article claiming that HA protein in both the virus and the vaccine could, in some people, trigger an immune reaction against hypocretin, was recently retracted because the data could not be reproduced. The symptoms were later confirmed to be compatible with narcolepsy. Northern Devon Healthcare NHS Trust: Consultant Gastroenterologist, University Hospitals of Leicester NHS Trust: Locum Consultant Paedatric Anaesthetist, Milton Keynes University Hospital NHS Foundation Trust: Consultant in Emergency Department, NHS Grampian: Consultant in Clinical Neurophysiology, Women’s, children’s & adolescents’ health. THL recommended that further Pandemrix vaccinations be discontinued pending further investigation into 15 cases of recently vaccinated children who developed narcolepsy in late 2009 and early 2010. [2] EMA is in the process of making appropriate changes to this website. While cautioning that the increase in risk for children is still uncertain in magnitude, it recommends they not be vaccinated. Originally it was thought that two doses given 21 days apart would be required for full efficacy. They found no correlation between vaccination and narcolepsy.

Pain, redness, swelling or a hard lump at the injection site, Warmth, itching or bruising at the injection site, Increased sweating, shivering, flu-like symptoms, Swollen glands in the neck, armpit or groin, Tingling or numbness of the hands or feet. H5N1-002 was initiated on 24 March 2007 in four SE Asian countries. In Sweden, MPA has discovered 12 confirmed cases and another 12 suspected cases. [20] THL later raised this figure to 17; the expected average annual occurrence is 6 cases. According to the authors, "the new finding of an association with infection, and not vaccination, is important as it suggests that limiting vaccination because of a fear of narcolepsy could actually increase overall risk. Their principal conclusion was that an increased incidence of narcolepsy was seen following a wave of upper airway infections (such as H1N1 influenza). General constitutional upset of sleepiness or sleeplessness, generally feeling unwell, dizziness. It’s very, very, very rare that you ever see anything that’s associated with the vaccine that’s a serious event,”1 he said. Les deux vaccins avec adjuvants les plus utilisés en Europe (le Focetria®, laboratoire Novartis, et le Pandemrix®, laboratoire GSK), utilisaient un adjuvant à base de squalène. [6] Stanford University studies suggested that narcolepsy is an autoimmune disease[7] and that it appears to be triggered by upper airway respiratory infections in China, where 2009 H1N1 vaccines did not contain adjuvants.[8]. If the site still contains content that does not yet reflect the withdrawal of the UK from the EU, this is unintentional and will be addressed. Since narcolepsy is now believed to be an autoimmune disease,[7] the authors suspect that these upper airway infections trigger an immune response which leads ultimately to narcolepsy in susceptible individuals. The vaccine was developed by GlaxoSmithKline (GSK)[1] and patented in September 2006. Le vaccin Pandemrix contre la grippe A(H1N1) distribué par le laboratoire GlaxoSmithKline est accusé de provoquer l'apparition d'une affection rare du sommeil, la narcolepsie. The marketing authorisation for Pandemrix has expired following the marketing-authorisation holder’s decision not to apply for a renewal. Peter Doshi asks what this means for the future of transparency during public health emergencies In October 2009, the US National Institutes of Health infectious … More detail is available in the summary of product characteristics, 28/04/2016 Pandemrix - EMEA/H/C/000832 - II/0079. [13], As of 3 December 2009, 11.2 million doses of Pandemrix had been delivered to health services in the UK, where the vaccine forms the bulk of the government's mass vaccination programme. H5N1-007 was initiated at a single site in Belgium (Ghent) in March 2006. However, further investigations indicated that "antibodies to influenza nucleoprotein cross-react with human hypocretin receptor 2".
