Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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)
