[h=3]Abstract[/h] Since 2012, there are not only trivalent inactivated influenza vaccines (TIV) but also live attenuated influenza vaccines (LAIV) available for children aged 2-17 years in Germany. The Saxony-Anhalt State Office for Consumer Protection conducted a test-negative case-control-study. The aim of the study was to identify the effectiveness of LAIV and TIV against a confirmed influenza diagnosis in children and adolescents in Saxony-Anhalt in the season 2012/13. The children had nasal swabs taken, which were further diagnosed in a laboratory using the PCR method. 834 patients of 15 voluntarily participating paediatric surgeries in Saxony-Anhalt were analysed by multivariate logistic regression with STATA 12. Controlling for age group, gender and month of the disease's onset showed an effectiveness of all vaccines amongst the 2-17 years old (38% with 95% CI: 0.8-61%; p=0.046). A differentiation according to LAIV and TIV demonstrated a significant effectiveness for LAIV (84%) in children of all ages (95% CI: 45-95%, p=0.004). After stratification for age groups LAIV was proven efficient in children aged 2-6 years (90% with 95% CI: 20-99%, p=0.03), whilst it led to a non-significant result in children aged 7-17 years (74% with 95% CI: -32-95%, p=0.106). There was no significant effectiveness of TIV seen in any age group.The Saxony-Anhalt State Office for Consumer Protection endorses the use of LAIV in children in accordance with the STIKO recommendations, as long as no contraindication is evident.
