Grippe

publié le jeudi 7 février 2013

Eurosurveillance publie plusieurs articles relatifs à la vaccination contre la grippe dans son numéro du 31 janvier.

Un article s’intéresse au taux de protection conféré par le vaccin trivalent au cours de la saison 2012/2013 au Royaume Uni.
Abstract
The early experience of the United Kingdom (UK) is that influenza B has dominated the influenza 2012/13 season. Overall trivalent influenza vaccine (TIV) adjusted vaccine effectiveness (VE) against all laboratory-confirmed influenza in primary care was 51% (95% confidence interval (CI) : 27% to 68%) ; TIV adjusted VE against influenza A alone or influenza B alone was 49% (95% CI : -2% to 75%) and 52% (95% CI : 23% to 70%) respectively. Vaccination remains the best protection against influenza.

Un autre article est consacré à la diminution de l’immunité au cours du temps, après vaccination.
Abstract
This study evaluates the influenza vaccine effectiveness (VE) in preventing laboratory-confirmed cases in Navarre, Spain, in the 2011/12 season in which the peak was delayed until week 7 of 2012. (…) These results suggest a low preventive effect of the 2011/12 seasonal influenza vaccine, and a decline in VE with time since vaccination.
