First seen Jan 25, 2026 · Last updated Apr 28, 2026 · Updated 11 times

Summary

This study looked at how two different COVID-19 booster vaccines affect immune cells in the lymph nodes of 12 adults who had already received at least three doses of an mRNA COVID-19 vaccine. Researchers used a needle to take a small sample from lymph nodes a few weeks after the booster shot. The goal was to understand the immune response better, not to test a new treatment.
