The novel influenza A(H1N1pdm09) virus emerged in North America in early 2009 and rapidly spread worldwide. In this study we report the efficacy of the live attenuated monovalent H1N1pdm09 vaccine and 2009–10 seasonal influenza vaccine in a randomized double-blind placebo-controlled trial.We enrolled 703 children aged 7–11. Each child was randomly allocated in the ratio 3:2 to receive one dose of...
The composition of current influenza protein vaccines has to be reconsidered every season to match the circulating influenza viruses, continuously changing antigenicity. Thus, influenza vaccines inducing a broad cross-reactive immune response would be a great advantage for protection against both seasonal and emerging influenza viruses. We have developed an alternative influenza vaccine based on DNA...
In a severe pandemic, rapid production and deployment of vaccines will potentially be critical in mitigating the impact on populations and essential services. We compared access to vaccines and timing of delivery relative to identification of A(H1N1)pdm09 and the geographic progression of the pandemic in the WHO European Region in order to identify gaps in provision. Information on vaccine procurement...
This study (NCT00979602) evaluated the immunogenicity and relative protective efficacy of one dose of influenza A(H1N1)pdm09 vaccine with or without AS03 (an α-tocopherol oil-in-water emulsion based Adjuvant System).Four thousands and forty-eight healthy adults aged ≥18 years were randomized (1:1) to receive one dose of either the adjuvanted split virion (3.75μg hemagglutinin antigen [HA]/AS03) or...
The recent emergence of severe human illness caused by avian-origin influenza A(H7N9) viruses in China has precipitated a global effort to rapidly develop and test vaccine candidates. To date, non-A(H7N9) H7 subtype influenza vaccine candidates have been poorly immunogenic and difficulties in production of A(H7N9) virus seed strains have been encountered. A candidate recombinant A(H7N9) vaccine consisting...
