NCT ID NCT05951920
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how two different COVID-19 booster vaccines affect immune cells in the lymph nodes. Researchers used a needle to take samples from the lymph nodes of 12 adults who had already received at least three doses of an mRNA COVID-19 vaccine. The goal was to understand the immune response triggered by each booster type.
