Influenza Vaccine Trial

Influenza (flu) is an infectious disease caused by influenza viruses. Every year, many millions of people around the world become infected. Older adults, children, and individuals with weakened immune systems are particularly at risk. The flu is also the most common infectious disease contracted while traveling – even though there is a vaccine available.

Since flu viruses constantly change, conventional flu vaccines need to be updated regularly. This study is investigating a new vaccine designed to provide reliable protection even against new virus variants. Its effectiveness is being tested in a placebo-controlled trial, meaning one group receives the actual vaccine while the other receives a placebo.
