Against the various infections that afflict our society, we are not all equal. Immunocompromised people have long deployed a panoply of protective measures to which we were little aware until the advent of the pandemic. People who are immunocompromised can be numerous (Table 1) and it is likely that we see them on a daily basis without knowing it. Their health conditions lead them to experience isolation and a higher level of stress and anxiety than most of us. Our Foundation aims to facilitate the lives of these people dealing with this problem by raising awareness among the population and developing tools that allow them to be better protected and adapted to their reality.
