Clinical Trial Summary

A randomized, single-blinded clinical pilot study to assess whether vaccination with live attenuated vaccines can induce trained immunity and cause beneficial changes in patients with COPD.

Description:

Single-blinded 1:1:1 block randomized controlled trial (with varying block sizes of 3-6), stratified by sex. A total of 60 participants will be recruited and randomly assigned with 20 in each treatment arm. Separated by three months, the participants will receive two doses of one of the following three treatments: 1. MMR vaccine (M-M-R VaxPro) 2. BCG vaccine (Danish strain 1331) 3. Saline (placebo)

Primary	Innate immune training.	Innate immune training, detected as fold-changes in cytokine production capacity of innate immune cells for cytokines such as IL-1ß, IL-6, IL-10, TNF-a and IFN-?, following pro-inflammatory stimulation from inclusion to 4 months post-inclusion.	From inclusion to 4 months post-inclusion.
