First seen Jan 04, 2026 · Last updated May 16, 2026 · Updated 19 times
Summary
This study tests whether giving a new long-acting antiviral medicine (CD388) together with the high-dose flu vaccine is safe and does not weaken the body's immune response. About 100 healthy adults aged 18-49 will receive either the vaccine plus CD388 or the vaccine plus a placebo. Researchers will measure antibody levels and watch for side effects to see if the combination works well.
