Griep

gepubliceerd op donderdag 7 februari 2013

In Eurosurveillance van 31 januari verschenen meerdere artikelen over de
griepvaccinatie.

Een van die artikelen buigt zich over de beschermingsgraad van het trivalente vaccin in het seizoen 2012-2013 in het Verenigd Koninkrijk.
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.

Een ander artikel is gewijd aan de daling van de immuniteit in de periode na de vaccinatie.
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.
