This is Yupeng Li from Merck. I am relatively new to real-world evidence and OMOP CDM.
When doing vaccine related outcomes research, I found a few obstacles and later listed some of them in the OHDSI symposium poster, “Quality assessment of vaccine concepts in OMOP common data model” https://www.ohdsi.org/2020-global-symposium-showcase-26/. @Christian_Reich have provided many good comments and suggestions during the Symposium.
Given the pandemic, upcoming covid-19 vaccines, and vaccine outcomes research needs, it becomes more and more urgent to have better hierarchy and mappings for all vaccine concepts. I’d like to follow up with the community to see if anyone is interested to improve the mappings and seek guidance on how to do it.
