In order to alert the population about the flu season and remind them to get vaccinated we went beyond the ordinary. We represented the presence of the Influenza Virus by actually building and installing a unique device, that was integrated with a video stream, which spew water vapor as people passed by, simulating a sneeze. A simple, effective and fun way to show people that we are all exposed to the Influenza Virus. In other words, we created the first billboard that had a flu in the world.
