NCT ID NCT05672355
First seen Mar 08, 2026 · Last updated May 25, 2026 · Updated 12 times
Summary
This study tests whether a new COVID-19 booster vaccine (GEO-CM04S1) works better than the standard mRNA booster for people with chronic lymphocytic leukemia (CLL). About 80 adults with CLL who have already had at least two mRNA COVID shots will receive either the new vaccine or a standard booster. The goal is to see if the new vaccine triggers a stronger immune response and helps prevent COVID-19 infection.
