PG - 6436-43 LID - S0264-410X(12)01171-1 [pii] LID - 10.1016/j.vaccine.2012.08.005 [doi] AB - BACKGROUND: The present study was a prospective observational study to evaluate the safety profile of Celtura((R)), a monovalent, cell culture-derived, inactivated subunit influenza vaccine prepared from A/California/07/2009(H1N1) with the adjuvant MF59((R)). Subjects were enrolled prospectively during the H1N1 2009 influenza pandemic at medical centres in Colombia, Chile, Switzerland, and Germany during the period December 2009 to June 2010. METHODS: Subjects ages 18 and older were followed for the occurrence of adverse events (AEs) for six months after vaccination. Adverse events of special interest (AESIs) were neuritis, convulsion (seizure), anaphylaxis, encephalitis, vasculitis, Guillain-Barre syndrome, demyelinating conditions, Bell's palsy, and laboratory-confirmed vaccination failure. RESULTS: Overall, 7348 AEs were reported in 2296 of 3989 enrolled subjects (57.6%). Only two AEs were considered related to injection site reactions. No laboratory-confirmed cases of influenza were reported. There were 108 medically confirmed serious adverse events (SAEs) reported among 73 subjects with 6 such SAEs described as possibly or probably related to vaccination. Three fatal cases were reported and assessed as not related to vaccination. Two AESIs classified as convulsion were reported and assessed as not related to vaccination. Both AESIs occurred well outside the pre-specified 7 day risk window representing the likely timeframe of the occurrence of seizure following vaccination. CONCLUSIONS: The results of this study support the overall good safety profile of MF59 adjuvanted cell culture-derived influenza vaccine as administered in adults during the 2009-2010 H1N1 influenza pandemic. No concern is raised regarding the occurrence of AESIs. CI - Copyright (c) 2012 Elsevier Ltd. All rights reserved.
