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.
The data from at least 99 individuals will be needed if the study is to draw reliable conclusions. One-third of these individuals will receive 3 injections in all: 2 on the first day and the third injection 4 days later (immunisation schedule 1). Another one-third will receive 2 injections in all: one on the first day and one injection 4 days later (immunisation schedule 2). The remaining one-third will also receive 2 injections, both of these on the first day (immunisation schedule 3). Participants will be assigned completely randomly (by chance) to one of these three groups. So each participant stands a 33% chance (a 1:2 chance) of receiving any one particular immunisation schedule. If you agree to take part, the process will be as follows:
