Easy answer: No, people don’t get that! One groups thinks it is simply immune (“I will never get influenca!”), the other ones think there’s a big risk in vaccines and then there are strange people believing there’s no virus at all or it’s all a pharmaceutical conspiracy. What they have in common is one simple fact: They just don’t think about risks for other people, they act in fact not social. There’s quite a chance that it could be their own fate.
