Analysis of health claims data on vaccination coverage in older adults in Bavaria, Germany: Influenza, pneumococcus and herpes zoster.

Background: Vaccination is essential, especially in older adults whose immune system function declines with age. The COVID-19 pandemic and its associated lockdowns temporarily disrupted routine vaccination services. We aimed to assess vaccination coverage for Influenza, Pneumococcus, and Herpes zoster among older adults in Bavaria over time and investigate potential pandemic effects on these rates.
