Design outcomes

Primary

MeasureTime frame
1. To assess the function of monocytes measured by cytokine responses after stimulation with unrelated antigens at different timepoints a. before and after single standard BCG vaccination b. before and after BCG revaccination c. before and after high dose BCG vaccination 2. To compare cytokine responses at different timepoints a. Between standard single dose vaccination and revaccination b. Between standard single dose vaccination and high dose vaccination. 3. To compare transcription and epigenetic profiles of monocytes before and after BCG (re)vaccination.

Secondary

MeasureTime frame
Identifying SNP variants of genes relevant for innate immune function. Cellular metabolism of peripheral monocytes
