First seen Mar 08, 2026 · Last updated May 15, 2026 · Updated 9 times
Summary
This study tests a new COVID-19 booster vaccine (GEO-CM04S1) in 80 people with chronic lymphocytic leukemia (CLL), whose immune systems often don't respond well to standard vaccines. The new vaccine uses a modified virus to better activate T cells, which are key infection-fighting cells. Researchers will compare it to the usual mRNA booster to see if it provides stronger protection against COVID-19.
