Clinical Trial Summary

Rationale: The effects of BCG vaccination have been only sporadically studied in the elderly, and the long-term effects of the vaccination have not been studied until now. There is evidence that BCG vaccination beneficially influences susceptibility and severity of infectious and inflammatory diseases; however, the specifics, extent and duration of these effects are not known yet. With this observational study we would like to determine the extent of these effects in the elderly. Objective: To identify any long term effects of BCG vaccination on the incidence of infectious and inflammatory diseases may have in the elderly Study design: Cohort study with a duration of 5 years Study population: Older adults who participated in two large randomized BCG vaccination trials in 2020/2021 (BCG-CORONA-OUDEREN, BCG-PRIME), who have consented to be contacted for further studies Main study parameters/endpoints: The incidence of infectious and inflammatory diseases in the placebo- vs. BCG-vaccinated individuals
