Summary

This study looks back at hospital records to see if patients who got a flu vaccine, took blood pressure drugs (ACE inhibitors or ARBs), antihistamines, or amantadine had better COVID-19 outcomes. Researchers will compare recovery and death rates among 3,000 patients admitted to one hospital. The goal is to find out if these common treatments might help fight the virus.
