Outcome Measures

Primary Outcomes (1)

  • Occurrence of a typical pock ("take") which is associated historically with protection against variola within one week after vaccination.

Secondary Outcomes (3)

  • Occurrence, relationship and intensity of any serious adverse event at any time during the study / any non-serious adverse event within 4 weeks after vaccination.

  • ELISA / Neutralisation assay specific seroconversion rates and geometric mean titres 2,4,12,52 and 104 weeks after vaccination.

  • Interferone-gamma producing T cells 2,4,12,52 and 104 weeks after vaccination.
