The study aims to answer this question: whether adequate immunity can be achieved in a short time, that is, by a rapid immunisation process, using at least one of 3 new TBE immunisation schedules? The investigators will test the immunogenicity (the degree of immunity achieved) of each of the immunisation schedules at various times after the injections. If the results of this clinical study are positive, it may then be possible to develop the most successful immunisation schedule so that it can be used routinely. This means that the results of the clinical study have an enormous practical value in preventing TBE in people travelling or moving into areas with a high TBE risk.
