[Once vaccinated, always vaccinated? A claims data analysis on repeated influenza vaccinations among individuals aged ≥ 60 years].

ABSTRACT:

Background

The Standing Committee on Vaccination recommends the seasonal influenza vaccination as a standard vaccination for individuals aged ≥ 60 years and as an indication vaccination independent of age. Empirical data on repeated vaccination are not available for Germany. The aim of this study was therefore to investigate the frequency and influencing factors of repeated vaccinations.

Methods

We conducted a longitudinal retrospective observational study with claims data from ≥ 60‑year-olds insured with the statutory health insurance AOK Plus in Thuringia between 2012 and 2018. The number of seasons with influenza vaccination was described and the association with various individual characteristics was analysed in a regression model.

Results

Included were 103,163 in
