[Enhanced Targeted Influenza Vaccines - New Evidence Shows Higher Effectiveness in Older Adults].

Seasonal influenza causes a significant burden of disease in the German population and is associated with high societal costs. Persons aged 60 years and older are particularly at risk due to immunosenescence and chronic disease and account for a large proportion of influenza-associated hospitalizations and deaths. Adjuvanted, high-dose, recombinant and cell-based influenza vaccines have been developed to improve the effectiveness compared with conventional vaccines. Recent observational studies show better effectiveness of adjuvanted vaccine over conventional vaccines and similar effectiveness to the high-dose vaccine in older adults. Some countries have already considered the new evidence in their vaccination recommendations for the current or earlier seasons. The availability of the vaccines for older adults should also be ensured in Germany to guarantee a high level of vaccination protection.
