Serologic studies for swine influenza viruses (SIVs) in humans with occupational exposure to swine have been reported from the Americas but not from Europe. We compared levels of neutralizing antibodies against 3 influenza viruses--pandemic (H1N1) 2009, an avian-like enzootic subtype H1N1 SIV, and a 2007-08 seasonal subtype H1N1--in 211 persons with swine contact and 224 matched controls in Lux...

The aim of the study was to investigate the association between contextual generalized trust and individual-level 2009 A(H1N1) pandemic immunization acceptance. A second aim was to investigate whether knowledge about the A(H1N1) pandemic mediated the association between contextual generalized trust and A(H1N1) immunization acceptance. Data from the National 2009 H1N1 Flu Survey was used. To cap...

Evolution of H1N1 influenza A outbreaks of the past 100 years is interesting and significantly complex and details of H1N1 genetic drift remains unknown. Here we investigated the clinical characteristics and immune cross-reactivity of significant historical H1N1 strains. We infected ferrets with H1N1 strains from 1943, 1947, 1977, 1986, 1999, and 2009 and showed each produced a unique clinical ...

OBJETIVO: Analisar as características epidemiológicas, similaridades e diferenças da influenza A(H1N1)pdm09 COVID-19 no estado do Pará, Brasil.

background: a new pandemic influenza a (h1n1) emerged in april 2009, causing considerable morbidity and mortality. since mutations in the haemagglutinin (ha) may influence the antigenicity and pathogenicity of the virus, continued epidemiological and molecular characterization for the effective control of pandemic flu and developing of more appropriate vaccine is crucial. objective: to monitor ...

background: influenza a (h1n1) pandemic is recently threatening the health of world's population. non-pharmaceutical measures are important to prevent the spread of influenza a (h1n1) and to prevent a pandemic. effective influenza pandemic management requires understanding of the factors influencing preventive behavioral changes. this study determined the status of preventive behaviors regardin...

BACKGROUND The 2009 pandemic H1N1 influenza vaccine had lower uptake compared to seasonal influenza vaccine, and most studies examining uptake of H1N1 vaccine focused on hospital-based healthcare personnel (HCP). Determinants of H1N1 vaccine uptake among HCP in all work settings need to be identified so that interventions can be developed for use in encouraging uptake of future pandemic or emer...

BACKGROUND As the incidence of H1N1 increases, the lay public may turn to the Internet for information about natural supplements for prevention and treatment. OBJECTIVE Our objective was to identify and characterize websites that provide information about herbal and natural supplements with information about H1N1 and to examine trends in the public's behavior in searching for information abou...

Background. Preventive vaccination is a vitally important strategic aspect of protection the population against severe effects influenza epidemics. The priority attention given to development effective tetravalent vaccines containing antigens two A lineages (H1N1, H3N2) and B (Victoria Yamagata) in combination with immunoadjuvants.The aim work was conduct preclinical study immunogenicity protec...

BACKGROUND During the 2009 H1N1 pandemic, pregnant women were prioritized to receive the unadjuvanted or MF59®-adjuvanted pandemic A (H1N1) 2009 monovalent vaccines ("2009 H1N1 vaccines") in Taiwan regardless of stage of pregnancy. Monitoring adverse events following 2009 H1N1 vaccination in pregnant women was a priority for the mass immunization campaign beginning November 2009. METHODS/FIND...
