[Influenza, tetanus, and pertussis vaccination coverage among adults in Germany]

In order to be adequately protected throughout life and to protect specific risk groups from particular diseases, regular booster or specific indicator vaccinations are also recommended during adulthood. Adults should be vaccinated against seasonal influenza (annually, e.g., persons with underlying chronic diseases and persons aged ≥ 60 years), tetanus (every 10 years), and pertussis (as a one-time vaccination with the next due tetanus vaccine and, e.g., when people have close contact to newborn babies). The aim of this study was to provide an overview of the current status of vaccination uptake among adults living in Germany, focusing on these three vaccines. In line with nationwide continuous health monitoring, the Robert Koch Institute conducted the representative study "German Health Update" (GEDA 2012) between 2012 and 2013. The survey is conducted regularly and adults are asked questions relating to their vaccination status through computer-assisted telephone interviews. Overall, 19,294 interviews were held. In 2010/2011 and 2011/2012, seasonal influenza uptake among persons aged ≥ 60 years was 54.3 and 52.6 % and among individuals with underlying chronic diseases 46.2 and 42.9 %. 7.6 and 75.6 % of participants reported up-to-date pertussis and tetanus vaccination, respectively. 22 % of people living with a baby in one household were vaccinated against pertussis. In general, vaccination rates against seasonal influenza, pertussis, and tetanus among adults are still low, but differ depending on the specific vaccination. The required aim of the European Commission to reach influenza vaccination coverage by the 2014/2015 winter season of 75 % of higher age groups has not yet been reached. The low pertussis vaccination coverage among persons in close household contact to infants poses a big challenge to the implementation of the cocooning strategy to protect the very vulnerable newborns. To emphasize the importance of a complete vaccination schedule and to increase vaccination uptake, tailored interventions should be provided for both physicians and adults.
