New study to reveal hidden weaknesses in vaccines for Immune-Compromised patients

NCT ID NCT06612515

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looks at how well vaccines against respiratory viruses (like flu or COVID-19) work in people with weakened immune systems, including those with blood cancers. Researchers will measure both antibody and T cell responses after vaccination. The goal is to understand why vaccines often work less effectively in these patients and find ways to improve protection. About 1,000 adults who are either immunocompromised or have a blood cancer will participate.
