Can esophageal cancer patients still fight pneumonia after radiation?

NCT ID NCT06181656

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looks at how radiation treatment for esophageal cancer affects the body's ability to respond to the pneumonia vaccine. Researchers will give the vaccine to 80 patients who have low white blood cell counts after chemoradiation. They want to see if the vaccine still works well enough to protect against pneumonia.
