First seen Apr 01, 2026 · Last updated May 14, 2026 · Updated 7 times
Summary
This study reviews hospital records of 3,000 patients to see if those who had a flu shot, took blood pressure drugs (ACE inhibitors or ARBs), antihistamines, or amantadine had better COVID-19 outcomes. Researchers want to know if these treatments are linked to fewer deaths or shorter hospital stays. The study does not test new drugs but looks back at existing data.
