Study Summary

This trial will study how our bodies respond to the flu, and how the virus is transmitted. They will use a safe, controlled form of the flu virus, and expect mild to moderate symptoms.

Who is the study for?
Healthy adults aged 18-49 who can follow study procedures and are not pregnant, breastfeeding, or planning to become pregnant. They must use birth control if applicable, avoid certain medications before and during the trial, not smoke or use tobacco products, and have no chronic diseases like asthma or heart conditions.Check my eligibility
What is being tested?
The trial is testing how people's immune systems respond to a controlled flu virus infection (H3N2 strain) and how this virus spreads in an environment. It aims to understand the body's defense mechanisms against flu and assesses the safety of exposing healthy individuals to this specific flu strain.See study design
What are the potential side effects?
Participants may experience mild to moderate flu symptoms such as fever, coughing, congestion, muscle aches, fatigue due to exposure to H3N2 influenza challenge virus based on previous studies with this strain.
