NCT01562444

Brief Summary

The aim of this study is to investigate the immunogenicity response in adults up to 10 years after one booster dose. Data collected from this study will allow for greater information to prescribers who administer TBE vaccine, so that they can appropriately time the administration of booster vaccinations to individuals who received different vaccination schedules and who live in tick borne encephalitis endemic regions.

    GMR values were tabulated by vaccine schedule using post booster vaccination titers as baseline. Post booster vaccination titer: GMT at Day 21 of V48P7E1 (for subjects who received booster in V48P7E1); Day 0 for subjects who received booster before V48P7E1 study start.

    At Year 8

  • GMRs Calculated to Post Booster Baselines in the Age Group of ≥ 50 Years

    GMR values were tabulated by vaccine schedule using post booster vaccination titers as baseline. Post booster vaccination titer: GMT at Day 21 of V48P7E1 (for subjects who received booster in V48P7E1); Day 0 for subjects who received booster before V48P7E1 study start.

    At Year 9

  • GMRs Calculated to Post Booster Baselines in the Age Group of ≥ 50 Years

Study Arms (3)

TBE_R Group

OTHER

Subjects who had previously received the Tick borne encephalitis (TBE) primary vaccination according to rapid (R) schedule i.e., on days 0, 7 (+3) and 21 (+7) in the parent study (V48P7) and who were administered 1 booster dose of Encepur adults either 12-18 months after R schedule completion or in the first extension study, V48P7E1 (NCT00387634), were included in this group. Subjects had blood drawn annually starting from year 6 up to year 10 after booster vaccination (for those subjects boostered before V48P7E1 study start, the blood draw occurred annually starting from \>6 years up to \>10 years after booster vaccination).

Other: Blood draw

TBE_C Group

OTHER

Subjects who had previously received the Tick borne encephalitis (TBE) primary vaccination according to conventional (C) schedule i.e., on days 0, 28 (+10) and 300 (+21) in the parent study (V48P7) and were administered 1 booster dose of Encepur adults in the first extension study, V48P7E1 (NCT00387634), were included in this group. Subjects had blood drawn annually starting from year 6 up to year 10 after booster vaccination.

Other: Blood draw

TBE_AC Group

OTHER

Subjects who had previously received the Tick borne encephalitis (TBE) primary vaccination according to accelerated conventional (AC) schedule i.e., on days 0, 14 (+3) and 300 (+21) in the parent study (V48P7) and were administered 1 booster dose of Encepur adults in the first extension study, V48P7E1 (NCT00387634), were included in this group. Subjects had blood drawn annually starting from year 6 up to year 10 after booster vaccination.

Other: Blood draw

Interventions

Annual blood draw at years 6 (Visit 18), 7 (Visit 19), 8 (Visit 20), 9 (Visit 21) and 10 (Visit 22)
