Position Paper on Adult Pneumococcal Vaccination Position Paper of the German Respiratory Society and the German Geriatric Society

Currently, the German Advisory Committee on Immunization Practices recommends the pneumococcal polysaccharide vaccine (PSV23) instead oft the pneumococcal conjugate vaccine (PCV13) for standard vaccination of adults >60 years. Whereas the efficacy of PSV23 against bacteraemia has been proven by numerous studies, there is increasing evidence that there is no efficacy against non-bacteraemic pneumococcal pneumonia. This is in contrast to PCV13, for which the CAPITA study has recently revealed an efficacy of 45% against non-bacteraemic pneumonia by the 13 vaccine types. In this position paper we argue that this decision is not justified by the available evidence for the following reasons: i) the main burden of pneumococcal diseases is non-bacteraemic pneumonia ii) the clinical evidence for the efficacy against pneumonia is of higher quality for PCV13 than for PSV23 iii) the duration of clinical efficacy PSV23 starts to decrease after 2 years, whereas this has not yet been observed for PCV13 in the CAPITA study for at least four years, and iv) herd protection effects observed after PCV7 infant vaccination program on invasive pneumococcal disease must not be extrapolated to PCV13 and non-invasive pneumococcal diseases.
