Childhood vaccination has become one of the most intensely discussed topics not alone in Romania but other European countries as well. Mass media articles, personal e xperiences claiming that vaccines have side eff ects and can even lead to autism have generated various responses among parents and determined various perceptions and assessments of the health risks. Certain groups have emerged in the middle of these confrontational debates: there are those who resist vaccination, advocating that they infl ict suff erance on children. Yet others who refuse vaccines because they fear the unknown, along with those who have not made a decision and still search for medical opinion, and those who insist upon gathering more information before deciding whether to get their children immunized etc. Each of these groups perceives and defi nes the risk in a diff erent way. A discourse analysis of the comments and posts identifi ed on various online platforms from Romania revealed the fact that the individuals who resist vaccination reframe the risk as unknown, while calling for a more informed decision from parents. These individuals do not bring any logical, practical, or scientifi c argument in order to support their position. Some of them even consider that a mandatory vaccination policy is a characteristic of a totalitarian state thus infringing upon the right of the population to free choice. Another result of our analysis is the fact that the majority of the online debaters tend to perceive the risk of non-vaccination as bigger than the one of vaccination.
