Governments that are thinking about how to vaccinate the population against #Covid19 should realise that vaccination is not just the physical substance of the vaccine entering the physical body: vaccination starts in our minds. If no more than 60% of the Dutch population is willing to take the vaccine, the problem of vaccination is no longer a purely medical challenge. Our society is at the present moment not just affected by a biological virus, but equally so by a virus of the mind: the conspiracy theory. People have always been susceptible to conspiracies, but internet has changed the game completely. It all the more shows us that our basic human intuitions viz a viz the world we encounter – that is, how we give meaning to the things we notice in our environment, do very much still contain the same forms of (collective) psychosis that we would associate with Medieval or even pre-historic times. We have never been modern. The task, then, of governments is not just to get rid of any virus particles hiding in our lungs – we need to think about ways to make us immune against conspiracies, and we need to start thinking about this fast, because that, I fear, is the real pandemic that could mean the end of us all.
