Immunogenicity of delayed TBE-vaccine booster

• Information is scarce regarding the antibody response when TBE-vaccine booster doses are delayed, which is a common situation in daily life. We have investigated the immune response after a delayed booster dose compared to a normal booster interval in an every-day setting. Overall, 250/260 (96%) of the study participants had neutralizing antibodies post-booster, with no significant difference between normal and delayed booster intervals. Based on our findings we propose that healthy individuals who have failed adherence to the recommended schedule of TBE-vaccination can be given a delayed dose without concern of immunogenicity.
