Summary

This study looked at how mRNA COVID-19 vaccines change the activity of certain immune cells (monocytes) in people of different ages. Researchers measured oxygen-related molecules produced by these cells before and after vaccination. The goal was to understand the body's response to the vaccine, not to test a new treatment. 30 healthy volunteers participated.
